|  Water current and the fish you keep. I'm pretty sure my 30 gal tall tank (20"w x 18"l x 20.5"h) has pretty fast current. I have a Penguing 350 biowheel filter which nearly spans the width of the tank. My concern is putting fish in there that can't deal with the current and end up dying from exhaustion. I have not really been able to find much on this subject. My danios seem to love it but the glow light tetras I recently added look they would rather be relaxing instead of flipping their fins all the time. I know tiger barbs are ok with it because I have had some in the tank. Looking for suggestions on other fish that enjoy faster moving water. |

That is quite a filter system that you are using for your 30g tank. I am using the same system on my 60g tank and it can accomodate up to 75g tanks!! Better overfilter than underfilter!! I have TB in the 60g tank and they love it. I also have Rainbow Sharks in the tank and they most hang out at the bottom of the tank, where i assume the current is a lot more calm. I am pretty sure that your tetras will soon realize that the top of the tank may not be the best spot for them. On a separate suggestion, you could purchase a BioWheel 200 which can handle 30g tanks. this may be easier on ALL your fish! | |

| I bought a used 30g tall that came with a an Aquatech 30-60 (I believe). It circulates the tank pretty good. I do not prefer that filter but so far I have had no problems.

| I run an Emperor 400 on my 30G. As long as the current isnt too fast your fish will adjust. However, if I remember right (I might be wrong), a current that is too fast can stress out your fish and lead to other issues.

| You can take filter media and string it to the water discharge ramp. This will slow the water down as it exits the filter and lower the surface current. I did that with a pair of Penguins that I was running on my 50 gal until I replaced them with a canister. You'll need to get a pack of "cut to fit" media instead of the penguin media. It's not the prettiest solution, but it works very well.

| I was thinking about blocking off the current like that, thanks for the idea Jedi. Also after reading replies I thought about the extension I have on the intake. If I removed the extension it would bring the intake up and possibly lower the current toward the bottom. I will try both of these ideas and see how it works. |

| the faster the current- the more energy they will use..you could always slow the intake down a bit this will slow the current- you could put some filter foam into the intake tube and adjust the flow. I believe that it is very possible to have too much filtration by having it generate too much flow and this unnecessarily stressing the fish

| I tried taking the extension off the intake tube and it made the current even worse. I decided to put a smaller filter system (penguin 200) in and I'll keep the old one for a larger tank I plan to buy in the future. Thanks for all your help. |
