My Plywood Build 250 Gallon

  • We are currently upgrading MFK. thanks! -neo
I have spoken with the people at drylok directly. Since Sherwin williams owns them and my brother has a higher up position with S/W it was easy for me to get in touch with them. They strongly suggested NOT using drylok on plywood or any wood surface for that matter, but I did it anyway LOL I personally loved the product and will use it again on a future project. Drylok can be used in fish ponds and my 800 was lined with hardie panel and drylok with me being the reason it leaked, not the drylok. I also made several (4) tanks with drylok on plywood, all of which failed horribly.

Thanks for the input.
 
Not to sound like a broken record but I am interested in how it will hold up under partial submersion rather than complete submersion. Will let you know soon. Gonna leak test the filter Thursday using one pump.

As long as you silicone the joints pushing it in you will succeed in holding water. But not for long term. Once the wood starts to expand and contract from moisture and temp change the drylok will start to flake off. It will still hold water but once the wood starts to rott it will fail.

makes sense, thats why alot of people use liquid rubber right? cuz it expands and contracts witht he wood? idk im kinda new to the whole DIY stuff so im just asking
 
TFG,

Thanks for the input. Will keep everyone posted on how it holds up.

Also, when I was testing the spraybars and the pump was creating a vortex at around 6" depth. Will a sponge filter on the intake cure that problem?
 
Tried the foam filter.. Restricted the flow too much, so I yanked off the foam and ran it with just the intake pipe. Perfect, no vortex.

Status....Waiting :nilly:

Pumps..on order, cant test sump.

Glass..on order, cant test fill

Sigh.. the wait is killing me, and I go out and check out my work, when I was epoxying one roller disintegrated while using, so I have rough areas all over the tank rather than a nice smooth surface, so cant really tell if I have thin areas. Thinking of being extra cautious and ordering another can of epoxy and putting on another coat for good measure. But will most likely wait till test fill first.

My pump solution,
