225 Gallon Plywood Tank Build

  • We are currently upgrading MFK. thanks! -neo
Got some of my Liquid Rubber today. I only ordered one gallon at first because I didn't have the spare money to order both at the time of purchase, but I will be ordering the second gallon once I get paid in the next couple days. It came from Rubberizeit.com and it's the Universal Grade(UG).

it wasn't too expensive compared to other products. I believe I paid a little over $80 for 1gallon. I've seen similar products go for $90-$120 for a single gallon and that's not including shipping. If you can't get your hands on Zavlar, then I suggest looking for Rubberizeit Universal Grade(UG). And a little goes a decent way with this. I'm thinking I might not even need all of both gallons for this build, but you can't be too safe so I will probably use all of the second gallon regardless.
 
I picked up two new Polypterus' today that will eventually go into this tank.
-Ornate Bichir (Polypterus Ornatipinnis)
-Albino Nigerian Senegalus (Polypterus Senegalus var. Albino)

With the addition of these two, the new expected stock list will be:
-Endlicheri Bichir (Polypterus Endlicheri Endlicheri)
-Nigerian Senegalus (Polypterus Senegalus)
-Ornate Bichir (Polypterus Ornatipinnis)
-Albino Nigerian Senegalus (Polypterus Senegalus var. Albino)
-Peacock Bass (Cichla Ocellaris)
-Pimelodella Four Line Catfish (Pimelodella Blochii)
-Royal Plecostomus (Panaque Nigrolineatus)
-Marbled Sailfin Plecostomus (Glyptoperichthys Joselimaianus)

As for progress on the tank, there hasn't been much. I've been really busy at work lately and I just haven't had the time to work on it. I do have all the plywood cut and ready to assemble, but I won't be able to get any more updates until my next off day, which hopefully will be soon! I want this done just as much, if not more, as everyone else!

Plywood tanks scare me. And types will eventually give out. 10 years tops usually

I have seen plywood tanks that are 10+ years and are still just as strong. One of the LFS I go to has a huge 800+gal plywood tank and it has been running for over 14 years (according to the owner).

BUT they do scare me as well. I personally have never built one so this is going to be a huge test for me. If this is a success though, I will be building much bigger and better tanks.
Once I find a good acrylic supplier I will try to build more acrylic tanks, but I haven't found any reasonable priced acrylic suppliers yet.
 
hi
as long as you take your time and use a frame to support your plywood ( you didnt mention supporting the tank) the tank will be stronger than any glass tank supported by silicone.
i built one almost the same size as yours last year and its strong enough for me to climb on top of it when cleaning the tank.
i also had never built anything remotely like this before, but i was able to learn everything i needed from the build threads here.
have a look at my thread and fire away with any questions or worries you might have, i got great help from the guys here and would like to return the favour,
cheers Paul

I have been thinking about adding exterior bracing/framing to the tank, but not many people do it with tanks this size. I see it more on tanks ranging from 500g - 1,000g+. It wouldn't do anything but help though so I probably will add some framing if I feel it's necessary. I can always add at a later time as well if I need to. We'll see how it holds up for the first few months after finishing then I'll decide if I'll frame it or not. I do want to add some reinforcement cloth to the corners and seams though just to give it a bit more strength.
 
yeah, the framing is overkill but as my tank is in my livingroom i needed to be sure.
i also clothed the whole tank as ive seen too many ply tanks leak because the water pressure caused tiny cracks in the waterproof coat.
Just a bit of friendly advice man, i hope your build goes smooth and i look foward to the progress pics,
cheers
