anarobic bacteria bubbles....

If you have plants in the tank already, I wouldn't take out the plates because you will rip a lot of the roots. If you don't, then yea, take out the fish and remove them. Try to keep the gravel as thin a possible, the more you have, the easier it is for anerobic spots to for due to a lack of circulation. The less the better. Make sure you do have plenty circulation in the tank. What kind of filter(s) do you have in the tank? Do you have anything like a powerhead?
 
well I have plants but none are over the plated areas of the tank so I'm thinking it would be alright, plus they haven't been in there long enough to have a substantial root system, enough to be affected by the plates so I think it'd be alright. Right now, besides the UGF, I have 2 Penguin 330 bio's.

(no powerheads)
 
Ok, take the fish out first, then take the plates out. I would get a powerhead so you will have more circulation to help prevent the anerobic spots. I have a Maxi-jet powerhead, it is excelllent. I would recommend the 600 model, it pumps 160 gph. That should be good for your tank.
 
how do you drive that ugf??????

if useing air I'll bet your pushing air under the plates.
If your useing air power try power heads or bigger pump with the air stones where you can see them.Also you can shift(dont lift) that plate around once in awhile helps get the flow back.

hey, WetmanNY, at least I'm listening

..that's still my final answer, Regis: carbon dioxide.

why would you think this is carbon dioxide? I thought that roots sometimes pushed out Oxygen near the roots, but CO2? How is that?

anona, ready to learn somthing new
 
anonapersona carbon dioxide is an end product of all aerobic metabolisms, even aerobic bacterial ones. Other possibilities include an eruption of methane, hydrogen sulfide, nitrous oxide, nitrogen-- none so likely.

But now that I'm hearing about undergravel filters, I think somefinnsfishy has a bead on it: plain ol' atmospheric air forced under the gravel plate. I used to get that myself, if I had the airline too far down the riser tube...

hmmm..... I'm not sure I'm understanding the question. I'm using an air pump that drives the air into the air stones in the tube thing. Do you mean to place the air stones a bit higher in the tube? Currently, they are to the very bottom of the tube and seem just below the gravel....that's not right? I've never used power heads before but have been looking into them...
