Hello. So I rejoined the hobby being out for 10yrs. I have a couple tanks running and have a question on one of them which is a 30gl tank with about a 12gl Wet/Dry I picked up used. I have been running the tank now for about 3 months. i used the Bio Balls that came with it. I have some what was Dry Rock in the bottom of the sump sitting under the Bio balls for added filtration. I then have the Bio Balls sitting on egg crate where the tank overflow resides.
About 2/3's of the Bio Balls are above water line with water trickling over them. The other 1/3 is constantly submerged. My question is whether I really need the Bio Balls at all any longer? I could add more Dry Rock in the sump, or a Bio Brick.
Also, if I remove the Bio Balls above the water line, I expect more noise. Is there a way to quiet it back down if i do remove them?
Any recomendations and thoughts on this are much appreciated.
