I spent about $50 this weekend trying to drill and pipe two 10 gallon
tanks. That is, hands-down the worst idea I've had in the last six
months. What a stinking disaster Man!
I'll not try that again, EVER! on a glass tank. I don't know if I'll
run a siphon or a couple sponge filters instead of a canister.
