300ish Gallon plywood - First attempt

  • We are currently upgrading MFK. thanks! -neo
FYI, this thread alone was the inspiration for me to start sketching up my own plywood tank.

I am truly impressed...
 
That looks amazing !
What kind of filtering setup are you going to use ?
How long does it take to get the bacterial filter going in a tank that size ?

I'm using a wet/dry sump which is still being built.

I'll be seeding the tank pretty heavily from my established tanks so shouldn't take terribly long to cycle. Just gotta watch my ammonia and she when it peaks.

Thank you. If you have any questions let me know.

Wait till I try to make it look like something. Up to this point has been a lot of I just want to get it done. I have trim and trim paint waiting to go on. I might be building lids for it today if I can get enough motivation.

And my pump should be in tomorrow or sometime early next week. I went with a Danner Hy-drive 19. Which should be 1900 GPH.
 
So here is an updated pic.

I put both my 30" t-5s up top to get an idea of lighting. I'd like some opinions on if it's enough or not. Kinda hard to tell with a photo though. It is High res however and you should be able to enlarge it by clicking on it.

That's my small diatom filter running on it sitting in front of it if your curious. Just trying to clear the water up a bit.

GREAT JOB.
 
So my Pump came into today so I set up a test to see if my inlet and drains would work and check for leaks. All I can say is I'm glad I'm testing everything. The pump seems to be in fine working order.

It's a Danner pondmaster 1900 GPH.

The issue I'm running into is the pump is pulling water from the test sump and filling the tank faster then my overflow drain can remove it. Inside the tank the drain side is a 30" long piece of 1 1/2" pvc cut in half like a channel. The water runs into it and out the bulk head with has a PVC T fitting on the back which runs 6 feet nearly straight down to the sump.

Here is what the inside the tank plumbing looks like. Each of these is fitted into one of my 1 1/2" bulkheads.

On the outside of the tank on the drain side. Here is my test set up.

The chart over in the DIY filter section suggests about 1350 GPH vertical flow for 1 1/2" pipe which is why I chose it. My pump graph indicates about 900 GPH at 6 feet of head height that I have so all should be well.

Any input is welcome.
 
It's looking like I'll either have to reduce the flow from my pump which would be a waste since the flow is damn near perfect for what I want.

OR use my incoming bulkhead as a drain as well and figure out a new in line from the pump. Which isn't too hard since I'm using 1" flex tubing.

So two 1 1/2" drains should keep up with it.


In other news the silicone and rubber cured on my sump so I set it in the shower basin and filled it to see if would hold up and as I guessed it did not. the box is fine but the acrylic I used wasn't very thick so it flexed and started to pull away from the sides until the point the water weight/pressure got to high and it peeled away.

So the sump just went back on the "TO DO" list. The box is usable but I'm starting to think I want a bit bigger one and am also considering going to a glass or Rubbermaid stock tank for piece of mind. I don't want any leaks under the stand and I'm already pushing the envelope with this build for tried and true practices or in my case trying new products and hoping to hell I don't end up with a swimming pool in my living room.
 
Damn bro, your build is looking fantastic. The few setbacks you have seen are minor compared to all the successes. You have done one helluva job!

Now, finish it up so we can see some photos of fish inside that monster!
