This is similar to the algae question below, however I feel its getting out of hand. Within 3 days my 24 nano had been covered in brown algae, then today I get home and the water is looking cloudy. These are my stats as of today: Nitrate 10, Nitrite 0, Ammonia 0, PH 8.2, SG a little low at 1.019. I just turned my skimmer on as well which has not been running the previous time. In the filter I use sponge, carbon and live rubble. Any idea whats going on? Cycling previous tanks I never seen this before.
