So I got a new light for my 55 gal amazon tank. Nothing much, just upgraded from the incandescent to florescent for fish viewing purposes. I dont have live plants, unless you count the algae. Its been there for a long time in small ammounts, I scrape it and keep it in check, dont mind having it at all. Since I got the new light It has started to grow a bit more. Again, I dont mind it and its quite miniscule. My question stems from an observation a few nights ago, when I noticed a lot of air bubbles comming off the algae ( I had fallen asleep on the couch quite early, prior to shutting the lights off) I dont usually look at my tanks at night, as the lights are off and I'm sleeping
I have heard reference to pearling and I think thats a refference to plants giving off oxygen or something? Not sure if thats what's happening, but Id like to know what those little bubbles are. Im pretty sure they arent hurting anything, Im just curious is all!
TIA
