523 gallon plywood build (pic heavy)

  • We are currently upgrading MFK. thanks! -neo
I'm surprised there isn't more interest in documented longevity of plywood tanks.


Well, you sure built yours nice and correctly. :)
Great that you are updating the thread.
So many people disappear after they fill their build, and one never knows if it still is ok later.

Thanks Paul! This is why I figured more would be interested. I know I've seen multiple questions about how long plywood tanks last but you just don't see updated tanks on here to know how long any particular tank lasted with that particular build method an individual used. There's just VERY little documentation post water filled and set up :(

This is an awesome tank and was looking to build one myself. I don't live too far if it would be possible to see it and pick your brain about the process
 
I have been going over your build thread for a good amount this past week. Im going to be building a 10x2x2 plyood tank in the coming months. Lots of great information. I think i am going to fiberglass the whole tank, and then go with an epoxy paint. Are you still happy you chose max acr? The black finish turned out great by the way. Im deciding to fiberglass the whole tank because itll have a ton of rock in it (mbuna tank) and ive read some epoxy can become brittle and impacts such as a falling rock could chip it. Whats your opinion on that? In your case you just glassed the seams not the whole tank correct?

If I had to do it all over again I would have glasses the whole tank, though honestly for no particular reason other than more overbuilding and peace of mind. I've had zero issues with the max act and that's with hundreds of pounds of saltwater dry rock in it and believe me I've dropped rock more than I care to think about. I climb in the tank every couple months, not to mention standing on the outside of the frame quite often with zero impact on the epoxy.
 
I will say this, at the end when I had extra epoxy and I just poured it onto the bottom creating a thick coat has probably saved some cracked epoxy from falling rock! The side walls have not had any crazy impacts so I cannot say how strong or fragile it really is.

Okay good to know, thanks for the quick reply. Im sure youve been asked these questions over and over. Its nice to be able to directly ask some one whos used max acr, and also still has a tank going strong for multiple years. Im sure you remember how it was doing research on different methods, everything is so biased. But none the less for some one who hasnt had any experience with carpenty etc... you did one hell of a job. Only thing ill be unfamiliar with is fiberglass work. Luckily ive got some good friends with lots of experiance with it. Anything helps lol.
