Help! ammonia/HLLE

[coolwine05]

I have a 90 gallon tank with around a 130lbs of live rock thats been up for over a year with a few soft corals, some lps and an anemone. It has a 1-1 1/2 inch bed of aragonite/live sand/ and a little crushed coral. My corals and anemone are getting huge and doing well the problem is my regal tang. He has H.L.L.E. i have been adding vitamin C, marine selcone, added a grounding probe, and offer him seaweed every day and still it gets worse. Today i tested my tank and i am puzzled, my nitrates are at 0, my nitrites are at 0, my phosphates are under .25, but for some reason my ammonia read at a little under .25. I use an API test kit. What would be the cause for a little ammonia in my well established reef? is it a bad test kit or how should i go about taking out that little bit? any help would be much appreciated either with the ammonia or the HLLE. Thanks, kyle

Does the tang eat well when you feed him?
Do you have any macroalgae you could offer the fish?
What are you feeding the fish now?

currently i feed him seaweed selects algae clips every day for him to graze, on top of that i alternate frozen plankton, emerald entree, and spirulena enhanced brine shrimp all soaked in vitamin C, and a few times a week marine selcone. He is a pig he eats any and everything i put in the tank.

Try switching test kits to see if you get a different reading. Use zoecon on meaty food for HLLE. Do a gallon a day water change, rather than period water changes. Be sure to use aged, aerated, well mixed salt water when doing water changes. Take a look at the info on HLLE in the info thread, FAQ, at top of this forum.
