Aquarium Advice Apprentice
all right, so my tank is in the cycling process. when i did my water tests this morning about 11 am, the ammonia levels have dropped off and the nitrite levels are rising. I leave for work at noon and when i get home 10 hours later there is this brownish-yellowish what residue all over everything: the crushed coral sand, the LR, and even the artificial plants i have in there. so my question is....what is this? is it just algae?
