On my coldwater 20 gallon tank, I've noticed that the inside of the lid is always wet & that includes the lighting tubes
Is it meant to be like that?
I've submerged the filter pump but the bubbles from the airstone are the cause of it. The tank's not filled totally, (about 1/2 inch from the "Fill" line). I've tried turning down the flow of air from the airpump, but that just causes the bubbles to only come from one end of the airstone. Not really that desirable.
Can anyone sugest something please
I want to get this sorted as I'm worried about the effect the water will have on the tubes. I've got a drip loop in the cabling, so I'm not too worried about that.
