Caribbean Biotope Seagrass Tank

Yes, I think that's the best way to go, with big angels-with smaller but tough tank mates.

With your plastic clips, maybe you could camouflage them with oyster shells and position them on the culches?

That's a great idea, thanks!!! Also, for other macros that I can keep near the sand bed, I can build mini cultches to Hide clips.
I don't know if I can keep grasses or not, especially with a hogchoker. So rocky attachment points are the ticket for the macros, I'd think.

Sorry to hijack your thread. What are your plans for your tank moving ahead once the treatment is done? Do you have ideas for a stocking plan? Not much longer to go!
 
Maybe you should wait on seagrass, or try just a small bunch to see how it goes. I'm not familiar with the species you have around there. I agree with the rocky attachment points. I've never had any luck getting macros to attach to anything. What has ironically worked for me is for the macros to starve, die back, then reappear already attached to random spots around the tank, when nutrient levels are adequate. Not exactly a method to recommend!

I don't mind the hijack! Since we're doing similar tanks, the discussion helps both of us.

I am getting excited at the prospect of moving on after hypo! Initially, I'll focus on rebuilding the bottom of the food chain. Then I'll see what macros can bounce back, and focus on what I want to keep or get rid of. I will try to limit the macros this time, so that my dosing goes to the seagrasses. I really want to get them flourish, after I get rid of the turtle grass. For fish, I'd like to rebuild the gramma harem and the barnacle blenny clan. I'd like to try sailfin blennies as well. Two males and four females would be the goal. I think I've finally decided to try the blue chromis-maybe 5-6 of them. I'm not sure yet, but I'd also like a harem of cherub angels- 3 or 4. If I do, I'll probably add another ten pounds of live rock for more shelter and diversity.

It's a lot to think about, so I better get with it!
 
I think the plan for this weekend is to do what I wanted to do last weekend. I guess I had to work up some commitment gumption. Pretty easy tasks, but some commitment required.

First, I want to try the boiling water thing on the aiptasia anemones on my live rocks in the QT. Regardless of the outcome I will then transfer them to the display, so any remaining 'nems will encounter hypo salinity.

Next, I will take the scissors to the turtle grass blades. This will be the least disruptive method to rid my tank of them. I imagine it could take months and many prunings to finally exhaust their nutrient storage, but on paper, it should work.

I've been looking at different macros, trying to find something that would grow on the back wall. This time I want something slower growing than caulerpa. And I want the seagrasses to have less competition for the nutrients I dose. I suspect I'l try several things and see what works.
 
Okay, commitments have been made.

I did the hot water trick on the aiptasias on my live rocks, then moved them up to the display. I also removed any remaining caulerpa that I found. I did this to kill off the last of the aiptasias, with hypo salinity. What I risk is killing desirables on the rocks, like sponges and red macros. Worth the risk I think.

Next, I got after the turtle grass, pinching them off just below the substrate surface. That was a lot of work. They covered about two thirds of my DSB. Now there is a plenty of real estate for manatee and shoal grass expansion. At first I stopped at the half way point, thinking it may be less traumatic for the tank. Then I thought about it some more. Since the turtle grass was already in a zombie-like state, I figured they might uptake MORE nutrients after being cropped, putting out new blades. Time will tell. The risk involved here is that I'm wrong, and a valuable nutrient uptake mechanism has just been removed and algae steps in to fill the void.

I'm very curious how long it will take to kill off the turtle grass. How many croppings will it take? I guess it will depend on how big the roots have gotten. Bigger means more storage for nutrient reserves. I worried about them dying, deep in the DSB, and what that would do. But after thinking a bit more, I expect the roots will shrink down as they give up that storage, eventually leaving not a lot behind.

So, the adventure continues! More risky moves made to get what I want, and more invitations for algae to make a comeback. Today's actions were one of the last hurdles. Now I wait and watch. Eleven more days of hypo. Wish me luck!
 
Wow, you've been busy! Good luck and hopefully all of your steps work out as planned. Makes sense to me! I'm excited to see the comeback, so I can't imagine how excited you'll be. Your tank will be fantastic!

Will you buy more manatee grass after hypo or just try and let nature take its course? I was thinking that if you added more, the balance of the competition between it and the turtle grass will shift, with the manatee grass having the ability to gather more nutrients (because of the turtle grass pruning). What do you think?
 
So it does make sense? Thanks Chasmodes! That makes me a little more confident.

More manatee grass would be great, and I think that would help tilt the balance, but Florida Pets hasn't had any in stock for quite awhile. I'll keep checking. What I'll probably do is strategically move some around. I've done a little of this before and they seem to respond well. I'll also try to favor them with some root tabs. And, I'll reinstitute the dosing scheme, which has been drastically reduced for hypo.

It's been a wild ride and a fascinating journey, employing nature to help me solve some problems with this tank. I had no clue that hypo would not only eradicate ICH, but also aiptasias and caulerpa. Bonus!

Some would argue that hypo isn't natural, but in the inland lagoon I'm modeling, hypo events do happen naturally. So it's natural in my tank, but not in a reef tank! Haha! Not sure I can come up with a natural reason for a 'charcoal event', but that is the extent of the man-made solutions I used. Wait, I used boiling water too. How about a 'temporary hydro thermal vent event'? Yeah, no. "This guy thinks he can do anything, and then call it natural", is what some of you must be thinking!

I think the biggest factor that has (thus far) kept me out of Algaetown, is the Ulva. I am very fortunate that it was able to survive and grow. Another, more subtle factor was my resisting the urge to 'clean up' less desirable macros that were hanging in there, doing their jobs. The Chaeto in particular performed well. It didn't thrive, but it adapted and continued to grow. And believe me, it isn't pretty! It was very tempting to remove it, when I was pinching the turtle grass, yesterday.

So the tank is uglier than ever right now, but I still believe it's gonna make it! Ten more days…

Yep, I agree, the way that I see it, you're trying to have as natural of a mini ecosystem as you possibly can. Since nobody can completely duplicate nature, we also rely on artificial measures to achieve our goals. What is different between our attempts at mini ecosystems, we're trying to keep all of our animals alive at the top of the food chain, while in nature that just doesn't happen.

Thanks Chasmodes!

Yes, I'm trying to take advantage of the natural processes that are there, ready to help me, both for day to day good system health, but also during this special treatment process. I used the ulva as a fast-growing export plant as a way to temporarily compensate for the loss of plant mass. It's pretty cool, using nature-based solutions, rather than man-made ones-no dangerous copper or other chemicals. Not that I've never resorted to chemiclean warfare, I'm just saying it will be cool if it works!
 
I lost another gramma, leaving one or two. I'm only seeing one, but there should be another. Or it could have died hidden in a cave. The only visible one left is the male. It was the largest female, that stepped up to manhood when Big Daddy died.

I had hoped to save all of them from disease. I didn't. Hypo salinity didn't fail me. It was my fault. I was too slow to begin treatment. That's the problem with curing sick fish-by the time you see symptoms, it could already be too late. Or if it's not, you have to correctly diagnose and quickly treat them to have any chance of success. I was way too slow. Lessons learned.

Now I need to focus on getting my little ecosystem healthy again. As soon as hypo is over, I'll be able to really do stuff. I can't wait! Two days after clipping the turtle grass, new blades are already a half inch tall. I think fast is good. The quicker they regrow, the quicker they use up reserves. I also noticed the the current is less powerful, with the live rock scattered about the right end of the tank. The ulva doesn't billow as much as it did before.

I've been thinking about what to plant on the back wall. I'm thinking I want something towards the top, that will shade the bottom of the wall, keeping it unplanted, so it doesn't crowd into the grasses. Having the wall in shadow provides a nice, dark background for the grasses as well. Plus I might get some encrusting sponges to grow there.

I'd like the rock DSB planter to be unplanted as well-not the DSB, but the rocks themselves. I think maybe I should just see what grows, and if some parts don't sprout something that'll be fine. I'd like at least some of the hardscape to show through.

On the fake roots, I expect the grasilaria hayi to come back in the same places it was before. I'd still like to get some sponges on the shaded roots. On the ones in good light, I'd like to get some nice, flowy weeds to dance in the current. If I ever decided to give up on sponges, I'd consider adding a light to bathe the roots in light, and just plant more plants.

But I won't give up without a fight. Sponges are just too cool. I think I am getting close to having some success. I think there is sufficient food and current. Dosing sodium silicate is another plus. I just need to get some good, healthy specimens, and get lucky with placement and orientation.

The detrivore community will need rebuilding as well. I'm not sure how much I'll need to add, and how much will come back on its own. I still have pods and snails. I'm not seeing spaghetti worms or mini brittle stars though. I'll get some more live sand and/or mud.

A lot to figure out. But of course, I love it.
 
Sorry to hear about your gramma, but although the treatment was in response to them getting sick, it was for the overall health of your tank, and you really had no other options. Your plan sounds very exciting. I like the idea of shading the wall because it was designed to be seen in the first place, and it looks so realistic. Sponges are so cool, so good luck growing them on the wall.

I wouldn't say that it was your fault that you started hypo late. You tried your best to catch the grammas and get them into QT. Hypo, at the time, was a last resort, if I remember right. Hindsight is 20/20, but you were being cautious with the best interest of the tank and the inhabitants in mind, nothing wrong at all with that.
 
I hesitated when I couldn't catch the grammas. Then I went back and forth on treating the display. If I had been quicker to react, things might have been different. But you are right, I had to also consider the rest of the tank and I just couldn't jump too quickly without looking at the overall system's health.

The real (and biggest) mistake was impulsively buying the Lookdowns…
 
The good thing about 20/20 hindsight though, is that we learn from our experience. And it's nice to be on sites like this where we can share our experiences and learn from each other. Don't beat yourself up about it though, because you've been very logical and thoughtful each step of the way. In the long run, you will be able to watch your tank with pride and awe, and hopefully, we will see it too :)

The lookdowns were cool. I saw some in our LFS last week. I would want some in my dream Caribbean mega queen angelfish tank!
 
True that Chasmodes.

Yeah, I'm not beating myself up too much, but I did want to point out my mistakes for others (and myself!) to learn from.

The Lookdowns WERE cool! That first day, when I had all three, that was the best fish watching (in my own tank) day of my life. It was amazing. The Lookdowns prefer to be in a school, and the way they swim together is the shizz.

Yeah, a huge lottery tank, with a school of Lookdowns, a mated pair of Queens, a harem of Rock Beauties, and a school of Banded Butterflies would be a sweet Caribbean community! Maybe a 10x10 would do it? Better make it 15x15!

Don't forget some a rock beauty, a french, a harem of bluehead wrasses, a school of blue chromis, a spanish hogfish, a redspotted hawk, a spiny boxfish, and of course, some molly miller blennies!!! :bounce3:
 
Six more days of hypo salinity.

I removed the next to last gramma the other day. That leaves just the one. He's eating and appears healthy, so I'm hoping he makes it. As sad as it is, I'm relieved to get the last sick one out. I need to know that my tank is free from sickness-at least as much as I can know.

Right now, the molly fry are the dominant species. It's good to have all those tiny mouths, eating algae. They're fun to watch as well. Ah, youth…

I haven't done a thorough inspection, but the aiptasias on the live rock appear gone. Same for the caulerpa. Since I've seen it come back from the grave, I'll hold off on declaring it eradicated for a few months.

Not much to show right now. It's still pretty ugly. As soon as treatment time is up, I'll starting increasing salinity and decreasing temperature. I'll probably do that over the course of a week or two. Not a huge rush. I've still got my battle with the turtle grass to look forward to as well. I wonder how long that will take. My guess is two or three months. I guess I should keep dosing to a minimum. Or would dosing help to speed up the process? Hmm.
 
Almost there. Five more days! Are you throwing a party next Wednesday to celebrate? :beer: :D

I'm looking forward to the recovery. Good luck with the turtle grass removal. It will be very interesting watching your tank come back as well as your future new additions.
 
I was doing some web research on Chasmodes bosquianus, the featured blenny that will be in my oyster reef tank, along with all of the other species of fish that I hope to keep, are also found in some mangrove lagoon biotopes! Our biotopes are pretty similar, even more than I thought. I don't know why I didn't realize it before, but it makes sense.

The big difference is that the Chesapeake lacks some of the more tropical blennies and gobies than in Florida, for example, but the ones found up here are also there. Pretty cool, I thought.
 
Yes indeed I am excited to get my little lagoon back! I think it will be a wonderful journey, to bring it back from miserable state it is in. I had to show my tank to a surprise guest today and I was mortified. "Here's my tank in the ugliest state ever. You like?" Mortified.

I'm sure I'll post pics of the recovery, just like I did with post-tang recovery. It's amazing how nature bounces back.

Our tanks will be very similar. Just a few degrees latitude different. I look forward to you joining the party! But you've got another super cool project to do first. I don't think I could summon the will to do two consecutive tank projects, but I'm sure there are benefits to it.

What is the common name of your blenny?
