Why do I show Ammonia

[dcombs44]

I have a 29 gallon tank with 10 gallon sump, been running almost two years. I constantly show ammonia at about .25 ppm. I can't understand it. I just did a 7 gallon water change, which is nearly 25% and i'm still reading for ammonia!!! Please Help.

whats the kit? ive got the same damn problem ive just come to assume the kit cant read low enough

It may be a kit problem. Has it ever read 0 ppm on any aquarium?

Are you using tap water in the tank?

It's red sea marine lab..

I use ro/di from my lfs...they have it in 100 different tanks that never read any ammonia...i guess i could take some water straight from the store and test it to see if my kit would test clean water for 0

I would try that before doing anything to your tank.

I had* that test kit. Comapred it to the salifert ammonia, it will always read .25, while salifert reads 0. It will always show a slight green color in it, even on freshly mixed seawater......dont let it worry you, your ammonia is zero.

Ignore that kit, it's a poc. Along with most of their other kits.

yea that brand im seeing the just generic brand

HOWEVER..theres a blue pill they make for FW parasites...and that stuff works GREAT..i had ich, and after treating with the classic nox-ich and taking DAYS for it to come off (i had an eel too soo salt was out of the question) i thought everything was fine..til i noticed VELVET. on one treatment, roughly 5 hours later i noticed a large improvement, and within 36 hours it was compeltely gone so..theres some good stuff they do, obviously not SW setups
