Oh, okay. Well, like I said, you could do a powerhead or bubbles... maybe someone else will have some ideas on that, as well.
That's good to know ive been considering a c-530justonemoretank;3640109; said:Canisters are probably going to be a lot more quiet than an HOB. The water coming out an HOB sounds quiet until it's night, and you're trying to go to sleep LOL then it can sound like Niagara Falls.
I have always liked Marineland Canisters, though many on here don't suggest them. No one ever explains why, and even go so far as to say "Don't get Marineland" and don't even give a reason! My guess is that folks are attached to the filters that they own, and don't want to consider any other, which is fine. I have Rena XP3s and XP4s, as well as the Fluval FX5 (the bane of my existence).
I've got 3 C-360s. They're a great filter and I've only had one issue with one of them, and Marineland sent me a replacement part for free. They also come full of media, which you're not going to get with Fluval and Rena -- these companies think you should spend even more money on the media after buying the expensive filters. They're so quiet that you don't even know that they're on. I have to check the top of the water for movement in order to know it's running. The C-360 would get you pretty much where you need to be in terms of GPH, and, as I said, this is a reliable and easy-to-use filter.

They still need plenty of surface agitation. Great input in this thread btw.justonemoretank;3640131; said:That's one of the things that HOBs are good for, really, and canisters aren't. The surface agitation is what my AquaClear 110 so loud. On my 180, where I run three canisters, I use a bubble wand hooked up to an air pump. The bubble wand is buried under some rocks, so you can't see it. On my 125, where I use 2 canisters, I have a powerhead for surface agitation. I also have a powerhead on my two 75's, both of which run canisters. Don't bichirs breathe air? I'm not really familiar with them, but I thought they do. If this is the case, I wouldn't worry about surface agitation.
