Need Clam Recommendations

[Albertan22]

I ran my ammonia and nitrate tests again (I don't have a nitrite kit) and got pretty much the same result. The ammonia could almost be interpreted as 0, but I know I've had the test return a "yellower" colour than that before. Maybe I'll take some water in to an LFS this weekend and have it tested. I think if I actually had ammonia in the tank I'd be seeing a reaction from the corals.
