Oyster Reef Ecosystem Tank

Hi Everyone.

Sorry that I haven't been around much. I'm a bit embarrassed to say that I haven't made much progress on the large oyster reef tank. Life got in the way. However, I recently tidied up my working area and have reorganized the oyster cultches (dry) and am in the process of adding more Gorilla Glue to strengthen them. The 20g version of the tank taught me that, to have overhangs, those bonds must be stronger. There are many "loose" oysters, ones that are glued in but wobbly. I want them sturdy, like a real reef. I have a buddy that promised to help me with my stand, and another one that promised to help me set up and plumb my tank (including the sump and future water changing station).

I do have an ugly version of an oyster reef tank as well as some brackish fish in QT. Between both tanks, I have 7 skilletfish, 3 blennies, 3 gobies, 5 sheepshead minnows, one rainwater killifish, a bunch of mud crabs, a hermit crab and a bunch of other hitchhiker type inverts. I was thinking about collecting more osyter shells and creating a new reef for the 20g so I can focus on finishing the big tank without using the cultches that I already made for it.

That said, I've kept up the river tank. I ditched the roots because they took up too much room. I'm in the planning stage of how to hide my powerhead. I may make a different, smaller version of the faux roots, similar to how Michael made his faux mangrove root. I may use materials that I have now, or perhaps, spend money, on some sort of sculpting material. I'm leaning toward Polygem if I do that.

So, what about the river tank? It's full of colorful fish life. My plants died off during the winter cool down and did not come back as they might in the river, partly because of my battle with cyano and I pulled out the remaining plants.

I killed off the cyano by adding a phosphate remover to my cannister filter, and using a green slime algae killer. I got fed up as constant water changes did nothing. This worked. My tank has been cyano free for 3 weeks now and looks pretty good.

I'm really stoked because I've introduced a new species, added more of species that I've kept, and they're very active and in spawning colors. To find out more, check out my latest video:

BTW, Michael, Dawn and others, sorry that I haven't been around. I'm catching up on your threads, lots to read, and I promise that I will participate once I catch up. I'm currently on page 65 of Michael's thread.

Best wishes to all!
 
Good to hear from you again, Kevin. Life does complicate things sometimes. Sorry to hear your roots didn't work out. They were gorgeous at least! Mine came out bigger than I wanted too. Glad to hear you're still plugging along!

Hah, I just caught up to my last post on your thread, page 74. My post said I was trying to catch up then on page 58 LOL.


I tried cutting the roots down, and still haven't completely given up on that, but, it's messy and not as easy as it would seem. Plus, they were built to fit exactly as they were from top to bottom of the tank. When I cut them down, the base didn't fit correctly, etc. So, I left them out until I could decide on what to do. On the plus side, at least the faux rock wall is highlighted more.
 
Your faux rock wall is stupendous! The root was hiding it, now it's free.

Thank you Michael. Now I need to find a way to hide that circulation pump. Ughhhh...

I have my old roots that I can cut, modify, repair...or maybe make a new rock structure to attach to the upper left glass. I haven't made up my mind.

I'm leaning toward the roots first, and if that doesn't work out, get to carving a new rock piece. If I do that, I may have it run from top to bottom, and add another circulation pump behind it for more flow. I'm on the fence about that, because there seems to be a lot of flow already.
 
Your roots did turn out nice. I don't know if it would work with your pump and roots, but maybe you could do something similar to the plastic pitcher I used in mine. Probably not. There's stuff specific to your setup I'm not clear on, so I'm sure I'm missing something!
 
Here's the latest update on my Potomac River Biotope Aquarium... I've added some plants and new fish caught two weeks ago, including one longnose dace, four rainbow darters, including 2 females, three greenside darters, and one fantail darter. I gave away a few fish to my buddy. I've been actually holding them for him (through QT and then into my display), from a previous collecting trip. It was good to thin the herd a little, because my buddies and I worked hard to collect more fish for our tanks as our local public Aquarium (GEPA). I have a few more longnose dace, a common shiner, and a couple central stonerollers in quarantine that I will add to the DT in about 10 days that we got this past weekend. My friend, Nick, also gave me some Valisneria for my tank, so I added it and added some plant food.

My 20g oyster reef tank looks almost like it did before, so I'll get a video together on that one day soon. I have a ton of work left on the video game (hiding my head in shame right now). Sorry I haven't been on much, as I've been out collecting fish or out fishing, which is my dominant addiction, of course.

Anyway, I hope y'all enjoy the video.

Your Potomac River Biotope Aquarium looks awesome! Wall-to-wall fish and all wild-caught! Very impressive, Mr Wilson. Lot's of great color and movement too. Love the Valisneria.

I have a 6 foot diameter round garden pond that I've kept goldfish and a hardy water lily in for around 15 years or so. The other day I was kneeling down close to it and I saw something. It was a dark, tiny fish! And there were lots more. For the first time ever, my goldfish bred and now I have 'wild' goldfish. Thought you'd be amused!
 
Wow Kevin, I did not realize that your thread was under the discussion topic so am only now catching up on it! I love the Potomac river biotope. Last I saw it, you were making the fake rock wall. You did an amazing job and it appears that your fish residents agree. Such an active fun tank, I love it!
 
Thank you so much Dawn. Sorry I'm so late in responding. A lot has happened with this tank since my last video. I obtained some Valisneria americana (that is native to my river) from a friend and also collected two species of plants from my river (water stargrass and curly-leaf pondweed). I jammed a bunch of plant food spikes into the gravel, have a heavy fish bioload, and do my best to keep algae at bay and the plant growth has taken off over the past week and a half. The collected plants were starting to die off in the river due to lowering temperatures, but have really greened up and grown in my tank. I couldn't be happier. Michael, you might like these plants!!! LOL

Love it! Looks great, Kevin. I DO like those plants! Great to see the lush growth. Nice video too. I like how you talked at the beginning and end, and in the middle, it was like a fireplace video. Nice relaxing vid to start my day. Yay!
 
It does look better. When you zoomed in, It looked like a scene in a natural stream! I noticed too that your fabulous fake wall has now taken a back seat to the plants and fish. It was nice to get another look at it. Best fake wall EVER!
 
Thank you so much Michael!

I might be having to put forth some effort harvesting soon. I kinda dread doing that for fear of hurting the plants. Before I do that, I might move the stargrass and some Val from the center and put them into the left corner to fill up that space next to the left glass. I will leave the curly-leaf pondweed alone. Maybe clearing that area out will give that pondweed more light. I've read that it doesn't do that well in fish tanks, but we will see. I'll keep trying. It doesn't make sense to me though because supposedly in the wild it can handle a wide range of environments and is very tolerant of pollution, etc.
 
I hear ya. Once you finally have luck with plants it's hard to mess with a good thing. I remember once my giant vallisneria took off, it threatened to take over the tank. I ended up removing it and trying similar plants that were less prolific.

Yours looks amazing. I'd let it be until it doesn't. Enjoy!
 
Oh man I really love the plants. I can understand why you are hesitant to risk rocking the boat when the plants are thriving. It would feel tragic for them to be negatively impacted and then watch them recede. I love the way it looks now, and it's so cool.
 
Thank you Dawn and Santa Monica!

Yes, SM, I agree that a wide shallow riffle would look really cool, especially if you could view from above and from the side. I was on a recent collecting trip in search of madtom catfish and we found almost all kinds of stream critters (dace, minnows, shiners, chubs, darters, minnows, suckers, madtoms and inverts) in less than 6" of normal flow stream levels. I love looking down at my fish from above, but it's hard to see anything in the current, but perhaps a wider, more shallow tank would enable that. It would be fun to have a tank, say, 6' long, 4' wide and like a foot deep with a max faux stream depth of 6". You could do a couple patches of star grass too. A deeper tank with a faux bottom for the shallows emptying into a deeper pool would also be possible, but a custom tank would be needed for that width. I think a nightmare, if I could afford such tanks, for me would be getting those tanks into my house and making room for them :)
 
Hi everyone. It's been a long time since I've posted an oyster reef tank update, so now I finally have something worth updating and showing. I've kept a sloppy tank with the fish and inverts since my last post about this tank, nothing like my 20g tank when it was in its heyday. But, I've added enough structure to the tank and cleaned things up, and I have a decent selection of fish and invertebrates, so I decided to resume some videos on this topic. I hope you enjoy the update.
