peter m Posted September 30, 2015 Report Share Posted September 30, 2015 I have a 4x2x2 with 46in air bar and canister, just added internal filter with air tube, lots of small bubbles now circulating in tank , can I have too much oxygen in water?

Goldie Posted September 30, 2015 Report Share Posted September 30, 2015 I would think it would depend on the number and kinds of fish you're keeping. Link to comment Share on other sites More sharing options...
Donny@ageofaquariums Posted September 30, 2015 Report Share Posted September 30, 2015 Microbubbles can annoy fish. I mainly oxygenate by disturbing water surface with filter outputs. Link to comment Share on other sites More sharing options...
pk333 Posted September 30, 2015 Report Share Posted September 30, 2015 Ok the air bar doesn't actually add oxygen in to the water. Gas exchange occurs at the surface, as long as the surface tension is continually broken. Bubbles fro an air bar breaks the surface, thus facilitating gas exchange. A return spray bar from a canister filter will do the same thing. Link to comment Share on other sites More sharing options...

P4rker Posted October 14, 2015 Report Share Posted October 14, 2015 Pretty sure too much oxygen is harming my java fern. O2 ⬆ = Co2 ⬇. Could anyone confirm that this would harm the plants, co2 deficiency? Link to comment Share on other sites More sharing options...
Cam07 Posted October 18, 2015 Report Share Posted October 18, 2015 That's a very good question, I would be interested to know about that to Link to comment Share on other sites More sharing options...
P4rker Posted October 26, 2015 Report Share Posted October 26, 2015 [MENTION=11836]Cam07[/MENTION] read up on it in the past and apparently not enough co2 will cause deteriation but i dont know specifics. Would be good to know if anyone else has info on it.. Link to comment Share on other sites More sharing options...
Delapool Posted October 26, 2015 Report Share Posted October 26, 2015 I've seen this come up before and hopefully repeating correctly. Pretty interesting question. The point was made that assuming lights were on, then plants will be consuming co2. So having rapid water movement would then mean the tank co2 is constantly being recharged and the 'new' co2 being delivered to the plants. So they thought it would be a good thing to have extra filtration. I have heard of one case in a goldfish for gas bubble disease if that rings a bell with anyone?

Lictoga Posted October 26, 2015 Report Share Posted October 26, 2015 I remember I think jaypee had gas bubble disease in his tank a while back Link to comment Share on other sites More sharing options...
