What is a good bio cube replacement pump, today i looked at the maxijet 600's and 900's, they only fit if you cut the intake tube back a bit. Them i looked at the Rio 600, and 800. What have you guys used to replace, upgrade your return pump?? Does upgrading your pump cause more of the water falling noise? BTW the Rio 600 and 800 fit with out modification.
