I do about a 15%(2.25 gallons) water change every Sunday. I baste the rocks, and clean the glass 3 times a week. I test my CA, and ALK once a month just to make sure it's all in order.
During the winter I top off about 1 gallon every three days. The summer usually requires about 1 gallon every other day. I have fan constantly blowing across the surface to keep the temp at 80.6. the specific gravity is 35.
I thought it might be pushing it adding the 2nd clown, but so far so good. Nemo, my original clown, laid down the law when Buddy was introduced, but that was it. All 3 fish get along splendidly, and the RG has plenty of nooks and cranies to hide in. I do keep a pretty close eye on them when I'm around, but I'm not to worried.
Nikki -I don't think you'd have a problem at all. IMO they are not as tough as some people make them out to be. I started with a Nano, and thanks to you guys and gals, continue to have success. You just have to make sure that, like any other reef tank, that all is in order. The only drawback I've noticed is that it's not big enough.
I'm probably going to be adding some more LR. I was looking at it last night, and it was looking like more could be added, but I'm waiting to add the sump. Once the equipment is out of the tank, I'll have more space to work with.
I'm still torn between getting the CPR CS50 overflow, or a U-Tube. I can't make up my mind. I've seen Wooddoods success with his CPR overflow, but I'm not sure if I want to spend $100 on one. I worry more about the syphon on a U-Tube failing.
