first hello to everyone i'm new here, sorry i dont have a picture to show you but, i have a 29 gal tank with a magnum canister filter and i had it set up for a week or two and then bought a "assorted afican cichlid" which i think is a yellow labid. anyway he/she is doing fine no signs of illness and been going for 2 weeks but yesterday i noticed all these tiny little white spots in my tank on the rocks on the walls everywhere and the tank is growing some red alge too. the wite spots are about the size of eggs but they appear to be moving around like they are alive and some sort of bug or something living on the alge?? i did some water tests ph=8 or so chlorine is 0 ammonia is 0 and nitrites are 0 so the water seems like it's pretty good but i have no clue what the little white spots are, they actually look like tiny airbubbles. thanks for all your help
