I came home from work today and bam! my tank is cloudy, theres a bunch of that rusty algae all over the sand and rock i have, a piece of the sponge that was growing on the top of my rock broke off and was milling around the bottom of my tank! I dunno if this was part of my bio cycle, but my ammonia is at zero, nitrates are at about 20.
thanks a bunch if you can help me out with some info,
