not really anything exciting to update this weekend, we're still waiting on the resin for the fiberglass, so all we've gotten done so far is getting the polyurethane on the stand and hopefully will get the finish boards cut tomorrow....
my plywood tank build
- Thread starter laura65536
- Start date
well today we finished putting the poly on the stands, and decided to go a different route with sealing the tanks, as fiberglass is a b*tch! We went to lowes and got some hardiboard, we're going to put that on the inside of the tank instead. We've already got most of the drylok on it, should have that finished tonight and we'll start getting it put in tomorrow. No pics to post until monday, we're busy with the tank, but there will be new ones up monday, it's coming along nicely so far.
had time to upload a few pics, all three coats of drylok are on the hardiboard now, but we're done for the day, tomorrow we'll start getting it put in the tank.
We got the 2x6's for supporting the tank today, and hopefully the tanks will be done except for glass by tomorrow, but we'll see how long it'll take to get the hardiboard in there...
I'm ready to get it done

I also used drylok on a much larger project:

Mine failed about a year later, but that was because I was walking around in the tank and broke the silicane seal on the bottom back :x
The drylok was not the issue , it was completely my fault.
Be sure to liquid nails the hardi panel on all sides and the bottom, making sure you use heavy weights to hold it in place while it cures.
If I were to do it all over again I'd liquid nails the bottom in place, let it dry.
Then install the sides siliconing them to the bottom. After that I'd do everything the same.
Just make sure you get the drylok on all the edges of the hardi pannel in order to seal it good.
Also, don't do any siliconing until the drylok fully cures after a week.
I currently have three drylok directly on plywood tanks, the largest being a 110. All are doing well and are in service still with no problems. I do not reccomend drylok directly onto plywood, these are test tanks.... as I've got floor drains
Again, my tank is 800 and did great for a year sealed with drylok untill I decided to be stupid and go for a stroll in it.... The thread I linked goes through every method I used in detail....
Also... your paroon sharks will eventually out grow your tank as they get massive... So I'd say tank mates are out of the question!

also, will the drylok stick to silicone? I was just wondering if we could throw another coat on it after it's all in the tank...we're going to wait on that now so it can cure, so we're off to work on the sump I guess...
nevermind about the silicone...we've got it figured out now, I'll post pics later, think this should work pretty well, and if we're lucky all the backer board should be in the tanks tonight!
this is what we got done....hopefully we can work on it a bit more tomorrow after our husbands get off work...
the first pic is of our daughter,who talked our friend's son into helping her move some scrap plywood to build her castle
liquid nails to attach the hardiboard.....
fitting up the second round of hardiboard to make sure it fit just right....
drylok on the sumps now....
and more for the sumps...

Why did you seam the back and bottom? Aren't the tanks 8'? I was forced to seam mine due to the 14' length, so I had to make a piece that went over the seam and used a snot load of silicone (GE I) to cover the seam....
