I still can't decide if I should get the seachem tidal 75 or the 110... people say that the 110 makes more noise and it has a lot of bypass when you fill it up with media, but then I think the flow from the 75 might be too little. This sounds crazy but it's going on a 30-35 ish tank (I know it's overkill) but I want the best filtration possible without it being a canister filter (no room for it). Now the prices do play a large factor here. The 75 is $100 aud, while the 110 is around $150 aud. I also considered two 55s since I heard that they don't have any bypass, but that's costing me around $200 aud... sorry no room for a canister and internals look bad. I did look at the aquaclears and they cost about the same price, even a bit more. Oh yeah, i think I'll be hooking it up to the side of my tank. Pros and cons of this?
