nothing to do with bikes but rather an aquarium project gone wrong.
i wanted to start my 90 gallon tank up again and i saw on some fish boards some really nice looking do it yourself backgrounds and landscapes that go into the tank.
I decided to embark on this project as well. so i formed the background out of styrofoam , coated it with cement, then applied a marine epoxy to the whole thing to seal it from the water. The product used was called gelcote fiberglass resin. i washed the background then let it soak in the water for a few days and emptied the tank and refilled. i throw in a few fish ( african cichlids) and they look fine. i go for a ride and i come back 3 are dead, the other 2 are gasping for air at the top of the tank.
I can still smell the epoxy in the water; it comes back eventually after water changes. i was talking to some marine shops and they say that it is the gelcote, but more specifically it's the catalyst ( hardener) thats at fault. i must have put too much of it in and the extra didn't combine with the resin, and it's leaching right now. they recommended that i pull everything out and give the background a scrub with scotchbrite and ammonia or acetone, then apply 3 - 4 layers of another epoxy on top. ( east system ), and this time getting the correct mixture of hardener to resin. this one says 5:1, the gelcote actually was 20:1 and i'm sure it was my fault that i did indeed put too much catalyst.
now i can pull everything out but here's the problem. It's going to be a HUGE pain in the ass to pull everything out again. the background has been siliconed in place so it doesn't float plus the tanks already filled with water.
My question to the everyone is can i just keep it as is and keep on doing water changes and that the leaching will eventually stop, or do i have to pull the background and landscape out and start again with another coating. any help would be appreciated. Thanx for reading my novel
