I did a water change last night, I was having some trouble with brownish algae growing on the sand, and after stirring the sand a little, I noticed some sludge, so (shame on me) for the first time, siphoned the sludge. Well that solved the problem. I have a few toga narcissus snails that I thought would take care of that stuff, but I guess it was too much for them, since I never saw them come out at feeding, I assumed they were always full. I am planning on getting some porcalin* snails to do some night shift cleaning work. Anyway, the MI did fine throughout the cleaning, as usual. The Algae food I give it is called formula 2. Anyone else giving their MI this stuff? It gobbles it up. The color food is called formula 1. Getting ready for my upgrade, and am very psyched. I am getting a larger skimmer next week too.for my 30 gal sump. Well I never heard from anyone on what types of fish I can put in with the MI. After the 210 is up and running, I am planning on getting another Idol, maybe two. Do you think there will be fighting between them? Would 3 Idols in a tank be too much?
