Hi Everyone! I am in the process of upgrading from a 5 gal that I've had for 3 years, to a 10 gal. In my 5 gal I have a Rosy Barb (3 yrs), an apple snail (3 yrs), and a pleco (about 3 inches - only had him for a few weeks). All of these guys will be moving into the 10 gal as soon as I'm done with the fishless cycle (almost done cycling - should be ready within the next 3-5 days). I would like to get some more Rosy Barbs to keep my current Rosy company. I'd also like to see some other types of Barbs in there. I wanted to get 3 or 4 more Rosy Barbs and 2 of another Barb such as a Tinfoil. Is this too much for a 10 gal? Also, my 10 gal is set up with a bubble wall 1/2 the length of the tank and a decorative bubbling treasure chest. I also have a HOB bio wheel. All of these are causing quite a lot of turbulance in the water. I know that it's good to have a lot of oxygen in the tank, but is there such a thing as too much? Would all the turbulant waters bother the fish? I read on another thread that you can put slits in the tubing to reduce the air pressure. Anyone else try this or have other suggestions to lower the air force without having to go out and purchase a new air pump? I even tried stuffing a bit of cotton into the tubing to diffuse the air, but it really didn't make a difference. I got this pump because it had 2 outputs, which I liked. I tried using a smaller pump with a T in the lines to bring air to the bubble wall and the treasure chest, but there wasn't enough force to make them both bubble. Any suggestions?
