My new 25G highly tweeked tank

Let me preface this with the new Tivo S3 is out and it will probably arrive the same day as I intend to really set up the tank. Talk about Christmas coming early. TWICE.

Ok. So I bought a 25G with an integrated sump and skimmer. Canopy with dual 65w PCs and a microfan. The return pump is a rio1400. the display chamber is just under 20G. The idea was to put it on my desk at work. Not knowing what I was going to get behind the tank I compiled a wish list that included the following items:
1) upgraded return pump
2) CL manifold giving better than 50x total (with main) turn over
3) "remote" DSB to denitrify and avoid an in-tank DSB
4) Keep everything in the sump
5) rolling Chaeto ball for export (i know its a long shot)

Here is a picture of what it looked like out of the box:

Initially I have 4 concerns
1) the skimmer is suspect in terms of efficiency
2) and it spews serious micro bubbles
3) who uses bioballs in a reef?
4) The overflow is seriously noisy

First, I am going to ditch the skimmer and bioballs and rings. I may try to tweak the skimmer later once it has something to skim. Second, the drip plate over them will be moved to the first chamber in a diagonal config to eliminate splashing and all that racket.

I have ordered all the parts for the CL and they arrive tomorrow. I am planning on drilling the intake 4 inches from the bottom in the area between the skimmer and the bioballs and placing the pump over the bioballs. I have a Mag9.5 that will fit in that space but will only be partially submerged.

So the first thing I tried to do was upgrade the rio1400 to a Mag5. Problem one was that it wouldn't fit into the opening but it was close. So I removed the foot plate and beveled the opening by like a millimeter. Slid right in but (insert problem 2) it wouldn't lay flat on the bottom since the baffle got in the way by just a hair. Took a hammer and knocked a (thankfully) small piece off the bottom.

Every thing looks good so I fire it up (think Paul Sr. yelling FIRE IT UP) and it's the loudest pump I have ever heard. I looks like the pump cavitates unless the input or the output are restricted. Calling Danner in the morning and put the rio back (as it is in the pic).

No one claimed it wouldn't be an adventure. I actually am one of those folks that jump to the equipment section of tank of the month first so i am giddy like a school kid about all of this.

So welcome aboard my adventure. I will go into much greater detail on other parts as I get to them. One thing that may seem strange is some of the equipment that I put on the tank. I am going to use this little guy as a test bed for some of the stuff I will ultimately move onto a big tank I am planning. This will also test some of the ideas I have for the big one on a smaller more forgiving (think less expensive) system. Also, I am going to include all of the mess ups I make in the hope that it will save others from repeating my mistakes.

I will post a big update tomorrow as I build the CL system.
 
So here it is as it looks now without the skimmer and the drip plate moved. Much quieter now. At some point I will add a stop on the outer edge so I don’t need the egg crate to keep it in place. I also put the mag9.5 in its ultimate home so you can get an idea where its going.

At this point I am going to do some research on what running skimmerless will entail. I would use the skimmer body as a DSB if I can figure a way out to get good flow across the top. I am going to post in the advance forum about it some time tomorrow.
 
How are you not dizzy? I am dizzy and i only read this stuff.

What tank is that? can i get a front shot...full frontal!

lastly where in chicago are you? if you need cheato let me know I am about to throw some away, so will gladly give it to you.

nice stuff, you are way more tech savvy than I
 
I am totally reeling.

I will get some front and top shots tonight. It's currently next my sink in the kitchen, so I can fill and drain it easily to get out construction dust. Which translates to the front is up against a wall.

I'm downtown. You?

Thanks for the offer for the chaeto but I'm not sure if I will be able to use it. As it is, the only place I would be able to put it is under the mag 9.5. Which would make it a pain to maintain even if I can get it rolling. Time will tell.

just let me know about the cheato whenever you need....the stuff grows like mad.

couldnt you put it where those bioballs are?
 
ok. wow that was a pain and i didnt get as much done as i was hoping.

Here the Ts are taped into place to get an idea of how long I should cut the flexi:

And with cut flexi inserted:

Promised front view with the canopy on:

And the back end. I will need to cut out a slot for the CL feed to go into. About and inch will do it:

And everything in place. I am short a ¾’ 90 elbo so the bulkhead isn’t connected to the pump input:

And how it looks running:

Here are my thoughts after setting things up. All of the PVC hasn’t been glued yet. I and going to leave almost everything below the waterline unglued so I can pull it out easily. I am going to let the flexi PVC rest but I have a feeling I am going to need to drill holes in the top to fix the manifold in place. I choose flexi rather than rigid tubing hoping it would allow flexibility to correct for minor fluctuations in how far the pipe inserts into the brackets. My impression now is that its too wobbly.

Any suggestions besides drilling 4 holes and zip tying it into the top?

Flow isn’t very high spread out over 6 outtakes. I expect to run with only 3 or 4 once livestock in it. I can rotate who’s closed once a month or so to mix things up. I have more of the black modular fitting to add but need to buy the pliers cause I cant get the extras to go on.

Spoke with Danner regarding noisy pumps. It appears that they are cavitating when left to run full flow. If I restrict intake or output they quiet down. Weird. Danner is sending new housings and impellers for both pumps. I spoke with Val who was very helpful. I am impressed with their customer service.

Tomorrow is add the remaining 90degree, glue, modify canopy then go out and enjoy a Friday night. Unless I have any problems, I will take it to the office Saturday and add RO/DI water and salt.
 
I'd put ball valves on every outtake to promote even distribution. This way you can tweek each fitting; you can even turn off three for a week and then swap the next week. This'll give you more random flow. Something I did on mine, and I like it. Just a little more work. Sweet setup!

Your going to fill your tank more, because the water is a few inches below the rim and the CL returns would cause some splashing=salt creep and noise. Tank looks good otherwise
 
Sorry for the lack of updates. I have been waiting for replacement parts for the mag drives and they came in last night. Danner was very cool about sending replacements, however they did not fix the problem. I have heard through the grapevine that there have been noise problems with some of them lately. I ordered a couple of quiet ones instead. Unfortunately, the new pump has a 1 inch output instead of the three quarters that everything is plumbed for.

Here's a picture of the reworked manifold. I just didn't like the flexing pipe so I did it with standard PVC.

Here's a close up of the pump in line. I am not worried about such a long draw on the intake side because the water level is at or above the impeller. Plus when the power goes down the sump water level will rise well above the pump, causing the pump self prime.

Well, I am off to MACNA the first thing in the morning and don't get back until Sunday night. I am sure I will plug in the new pump when I get home but doubt I will update before Monday.
 
I have the same tank in a flatback hex. I love it. I use the skimmer and it really works well for me. Where did you buy your tank?
 
Old Town aquarium on Wells. They wanted to sell me a flatback hex as well, but I wanted a regular rectangular.

In the first picture you can see the bubbles flowing out the bottom. Is yours IPI? is your bottom of fully open or is it partially restricted? I think if I were to put a pair of baffles, it would restrict the micro bubble somewhat. I know when I upgrade the main circulation pump it will just make it worse.

Did you have to tweek it to get it to not blow microbubbles? I am probably going to take the protein skimmer body and make a deep sand bed out of it. I have not started doing research on highend HoT skimmers yet. I hear the Remoras are good and I love MRC. MRC says they are going to start making them but I can wait since I am planning on doing five to 10% water changes per week. Especially early in the tanks life.

I also re-worked the intake bulkhead and feed to be one-inch for the new pump. I don't buy much when I'm there but I swear I should get frequent flyer miles at Home Depot.
 
That is where I got mine. I have the same lights as you and love the tank so far.

My bottom is fully open, i have some microbubbles, but nothing to worry about. I found that by increasing my water level a bit they started to go away.
 
yeah, I tried various water levels as well. I also tried restricting the amount of air that went in and that only made it worse because the pump pumped more water. I bet if I were to restrict the amount water fit into the pump that would help, but what is the point.

At this point, I'm planning on keeping a pretty low bio load. Probably just a pair of percs. I know that there are lot of skimmer-less threads out there but I want to get live rock into the tank before I worry about the skimmer.
 
Quick update. Got the tank on my desk at work and going to fill it with water tonight after everyone leaves. I am still dragging a couple of plumbing parts to get the CL going that are supposed to show up tomorrow.

I ordered detrivore/live sand activators that are arriving on Friday so I had better get the plumbing parts by then. I'm hoping to order live rock for Friday delivery as well.


will post pics in the next couple of days.
 
Wait, quick question. What company makes this 25gal and how much was it. Because my money is just burning in my wallet looking at the tank....

Steve :D
