800 gallon plywood catfish tank

  • We are currently upgrading MFK. thanks! -neo
Can't wait for my flatty, blue, and RTCxTSN to go in. My blue is really outgrowing his 180. So overall here is a summary of the system.

The tank is calculated at exactly about 800 gallons. 3 twenty five gallon sump filters are filled with PVC ribbon and foams. A simple storage container houses the floss and holes trickle water over media. One sump flows into the next and into the next. I settled on the Iron Might pump which is fairly quiet and is very energy efficient. All plumbing is PVC. Two discharge nozzles make surface and bottom circulation. In addition, a circulation pump at 800 gph with air stone in suction provides strong bottom current and fractionating. Three bulkhead overflows put water to sumps. Lighting is on simple timers using led strip lighting adhered to a 2x2 played on top of lid. Lid is made of clear poly carbonate roofing panels. I also plumbed a bottom drain in a sump of the sand to do water changes and flush waste that accumulates there. The blue max was painted with black fusion with black waterfall foam for texture here and there. The product that truly made this a great build is the Chemlink M1. I highly recomend it for unique aquarium sealing conditions. I used a bead in seams before using bluemax to provide an elastic bridge over critical areas. I also applied a bead after blue max. That coupled with two layers of fabric in the liquid rubber provides a very durable yet flexible transition.
The sand is pool filter sand with small riverrock s mixed in. The tree was from a lake that it had been soaking in already. It came from area I caught state record Flathead in for good measure:)

Nice build. Was curious to know how much building the tank cost for all of the materials. Thx.
 
Plan to put flathead in tomorrow and he can clean house! After a couple weeks I will put blue in. The red tail needs to grow out a tad more so he is going in 180 after blue is out. Flatty is bigger then I thought and he might devour him!

I've got to calculate up total still...

awesome
 
If Pookie ever comes out of his new tree, I'll get a photo! Haha. So far all is good. Cycle appears to be in order with ammonia 0, Nitrite 0, and nitrate 10. Safe start has always been excellent for me. Been starting a light feeding regime for the sunfish until Pookie becomes friends:rolleyes:

Also dosing three days of melafix as normal for new additions.

Meanwhile I'm finishing the room. Want to install floor this coming weekend. If two-three weeks goes by and all are healthy and flatty is eating. I will add Bubbles the blue cat. He's going to be fun due to his size. I had to buy a new net to be able to handle these guys.

The second pic shows how many bubbles froth up after melafix.

So far OK. Been a few up and downs on the cycling. Ammonia was getting to be a problem at times. Just installed the drip water changer. Fish are eating well.
Did not like blue led lighting, so I've got to get some actual moonlight led for night.
Finished the room this evening and my brother came over to take some professional pictures of the tank and room. Anxious to get those back.
Yay!!!!
