This may sound like a simple question, but I'd like some clarity on it, on a canister filter, can you submerge the spraybar outlet pipe (the pipe where the water comes out) into the water? From the manual, it doesn't say, and it looks like you keep it above, but can you put it into the water, and if so, do you submerge it? The turtles might like water hitting them, but at the same time it might be noisy, so...
Secondly, is it better or worse to use the inlet strainer (the thing at the end of the intake to block out big things) in turtles? Since turtle waste is a lot bigger than fish waste, would it be better to not use one, and just leave the pipe open, or should I use it anyways (if the filter isn't supposed to take in big waste things or something).
Lastly, what are some good types of filter media? I just bought a Rena xP4, and there's a one or two empty baskets, so what are some good types of media to throw in, and is it better to have more biological media (stars and rings), or chemical media?
