Thanks. I hadn't tested Nitrate is awhile. I did a 25% water change last night before I read your post about nitrate. I just tested and it is about 15.
I think I overfeed. Also, I only clean my Aquaclears once every 6 weeks by swishing the foam in water from the tank. Should I do that more often?
Don't think I am nuts but I am a newbie still so took a photo of what I feed, twice per day!
Thanks for having a look. Oh, I have 7 saulosi in this tank. 5 are 1 1/2 inches, 2 are close to 3 inches. Tank is 37 gallons, run 2 Aqua Clear 50's.
