My friend has a submergeable heater. Could he just lay that in the sand, or will it still have a chance of melting through?
. . .
Playsand for substrate. like 3 bucks for a 50lb bag at lowes which is more than enough for that tank so he would have some leftover.
I would also reccommend quilt batting for filter media. I bought some from walmart and its only 9 buck and i got about 87" by 91". just make your own filter cartridges and you can add as much media as you want. . .![]()
My friend, who is tight on funds ATM, wants fish, so he got a bright idea, will it work?
He has an unused 30 gallon see through rubbermaid plastic container. He's "modded" it to fit his old filter, but he's worried about heaters, will they melt the plastic? He's also rigged a light for it.
My question is, would this be a viable way to make a coldwater aquarium if you're tight on funds? Is it safe for the fish? Is a heater on it a good idea?
