I'm trying to figure out a way to get more oxygen in the tank without taking out CO2. Would using an air pump to run air stones inside my HOB filters make any meaningful difference to how much oxygen is getting into the tank? Thanks.
Hey Everyone! I was looking to get better oxygen into my 55 gallon tank. Over the summer, I had bought the Top Fin Air Pump 8000 (http://www.petsmart.com/product/index.jsp?productId=3742976&lmdn=Product+Type&f=PAD%2FpsNotAvailInUS%2FNo) which is rated for up to 170 gallons. I have not been happy with the output of bubbles from my bubblers. It does not work as well as I would like. A couple days ago I noticed my goldfish gasping for air. I have a canister filter, so I turned the attachment towards the surface to create surface action and they look a lot better. I was looking into powerheads as a permanent solution to the oxygen dilemma, but I keep reading horror stories about fish getting sucked into them or stuck to them. The powerhead I was looking at is the aquaclear, either the 70 or the 110. I was leaning towards the 110 because I want to look into upgrading their tank size soon and wanted to future proof my purchase. (http://www.amazon.com/AquaClear-Powerhead-110-Gallons-Hour/dp/B0002DHMYW/ref=sr_1_1?ie=UTF8&qid=1393014395&sr=8-1&keywords=aquaclear+powerhead+110) Then I noticed that the powerhead doesn't have anything to stop my fish from getting stuck to it. I notice some powerheads have a thing on the intake that looks like the bottom of a filter intake. My questions are: 1. How can I get more oxygen into my tank without putting my fish at risk of injury or death? 2. Should I buy a powerhead? Which size can I get that will work with my 55 gallon, but will also work with a bigger tank when I upgrade? 3. If buying a powerhead is too risky, how do I get my air pump to work better?
Is there a more efficient/proper way to set up spray bars? 1) I've noticed that If I set the spray bar a little higher than my water line, the output splashes with more force which creates thousands of mini air bubbles that flow through the tank. 2) If I set the bar up on the water line, the water just comes through with little splash and doesn't create as many bubbles. Is option 1 more beneficial for the fish/water quality because of the bubbles. Bubbles do bring gases to the surface I've been told or read somewhere.
