Just make sure the output is disturbing the waters surface. That is all I do with my canisters and seems to work out just fine for introducing oxygen back into the water. Also if you can get the water from the bottom to keep cycling to the top and your good to go.
You guys are right! That was the first thing I noticed when I started it. The only way to get any surface agitation was to lower the water level. The filter really works great. My water is crystal clear. Im using my AQ70 from another tank to cycle so *** got some oxygen going back in the water. Isnt there a imput output kit you can buy with a spraybar? Or I could make something out of pvc. Any ideas would be great.
How close should the intake be to the bottom? The intake is short but I do have this canister on a tall tank.
I called marineland. Give her the serial number and mines 2 years old. She told me what the serial number should end with on a new one. Call LPS where I bought mine and had the guy check the number on the other one he had in stock. Its this years model. So I'm going swap them out. For anyone that is thinking about buying a c-220: if the last two numbers are 32 it's new. If the last two numbers are 31 it's last years model and so on...
