Painting acrylic Inside the tank

[wednesday13]

Ive used flexseal on a couple glass tanks. I like the look but it does not last, peels up after a couple years. I actually just broke down my 200g because of this, the whole bottom peeled out in a few big pieces.

Maybe itll work better with acrylic? Idk.

Dang… i think thats what i needed to see tho lol… i could probably get it to adhere fairly decent with sanding the acrylic down. I know its pretty much inevitable to peel at some point down the road to haunt me. Thanks for the feedback man

For the time and expense of some of these considerations, couldn't you just make the sand bed deeper and reduce the chance of the bottom showing? I'm stingy with my spare time too, and seems like less work

Pretty good point lol… wanted a bit of extra assurance just in case. I guess for $100 in epoxy or another type of paint that would also get me another 55lbs of red garnet sand. Its usually around $80-100… kicker is my last batch took 6 months to be delivered.

Maybe even try mixing it with black sand, not sure what that would turn out like

Sorry this is so late. I painted the bottoms of both my acrylic tanks (450 gallon and 1100 gallon) with DryLok paint. This is stainable. I use two different brown stain colors so it wasn’t all the same shade. Works great. Hasn’t peeled at all for over 4 years now. It’s all in my 1100 build thread if your interested .

Wow, would have never thought to use that. Did u use the oil base or water base? Actually have both kinds on hand. Ill read through ur 1100 thread again. Thanks Egon!

I like it with two different shades and a light amount of gravel on top. That way when the fish move the gravel around you don’t see the white styrofoam under. I can’t stand when that happens. From now on every tank I own will get a coat of this on the bottom.

This is my 450. You can see the bare spots where the gravel has moved. Also a pic of the background. It wasn’t tall enough so I stacked white styrofoam 3 or 4 levels high and staggered them to slope back. Then I painted it with drylok. I think it looks great. You can see a few spots of white showing through but it’s 4 years old now.

This is my 1100. Larger fish and gravel. This stuff is strong. No peeling at all.
