Hello, I have a problem with some sort of brown/red algae. It is on my subtrate, kind of like a carpet. I can stir the subtrate up and it kind off cleans it up, but if I don't stir it up it gets harder and stickier. It also disappears at night under the moon lights. The subtrate turns to...

I just did my first test for ammonia and pH, and the results are quite confusing. The ammonia test shows 0.1mg/L but the water in the test tube is very cloudy, and the color is neon like green that corresponds to 0.1 on the color chart. For me it is very strange because I use the same test kit...

Hello, Just set my nano reef tank. I got my filter, PH, and thermometer running. I put in my salt mix. I was surprised how much salt mix I had to put into my 20G to get the proper salanity. I was adding it with table spoon, then went to 1/2 cups, and then I just starting using full cups...

Hello, I was wondering if the output of the power heads can be added together to get the required water turn over or does each power head has to have the needed turn over rate. For example if I am aiming at a turnover rate of 600gph do I need to purchase 2 or 3 PH that have 600 rating each...
