I’m having trouble controlling the ammonia in my 25gal QT. I’ve got 4 fish (sm. sailfin tang, black darwin clown, flame angel and a scribbled rabbitfish) in QT right now.
The tank was filled with water from DT on 5/19 and I added 30ml Dr Time’s One & Only. It has been running with a HOB filter with ceramic bio and a sponge, as well as an airstone since then. The tank had 2 wks to cycle. I did not add any ammonia to feed the bacteria during this period. I also neglected to do any testing as I figured by using DT water I was good to go.
I dosed CP on Sat 6/2 in the AM at the rate of 40mg/gal as I was planning on visiting my LFS that day. Fish were acclimated that afternoon and by Sun. all were eating and looking good. Same on Monday. But Tues AM I noticed that they were less active and lees enthusiastic about food. My Ammonia badge showed yellow but after closer scrutiny I’d say maybe slightly greenish. My Red Sea test kit showed ammonia at approx 1.5-2.0ppm with Nitrates @ about 10ppm and Nitrites at 1ppm. Consultations with R2R members that day here:

By late afternoon rabbitfish & tang were listing slightly and all 4 looked somewhat distressed. I mixed up 10 gal of fresh saltwater and brought it in from garage to acclimate to QT temperature. Did a 10 gal WC Tues night which lowered Nitrates & Nitrites by about half but ammonia still looked high using Red Sea test. Ammonia badge still yellow w/slight greening but fish perked up considerably. Added another 30ml Dr. Tims.
Wednesday was a bit better. Rabbitfish eating as were flame angel & clown. Tang still a bit slow and while he approached food did not actually eat anything. Made up another 10 gal batch of water and did another WC Wed evening. Added another 50+ml Dr. Tim’s and crossed my fingers
Thurs: Got Seachem MultiTest Ammonia kit and a new ammonia alert badge. New badge now same off yellowish color as old one and MultiTest shows a minimal amount of FREE ammonia (.01-.02). total ammonia in the .15-.20 range.
Really not too confident in color comparison of MultiTest kit. I used their sample which is supposed to come out at 1.0mg/l but it looked to be more gray than greenish blue as on the scale.
Over the weekend: Did another 5 gal WC. continuing to get troubling readings on the Seachem Multitest kit. Called Seachem on Fri to ask about color of test sensor not matching chart and was asked to submit a photo which I did no word back yet. Ammonia alerts still show yellow with a slight green tinge. The Seachem Multitest kit shows 0ppm for free ammonia but total ammonia is off the chart which goes to blue and my sensor is now looking purple. All fish eating except Tang who responds to food being placed in tank but I have not seen him actually eat. He may be eating off bottom after I leave. Bought some Prime on Sunday and added 5ml to 25gal which is double the dosage. Still getting high numbers on Monday.
QUESTIONS:
Could the bacteria have died during that two week period with nothing to eat?
I think I may have too many fish for a 25gal water volume but don’t have any options tank-wise right now. What should I do to keep ammonia under control for the duration of this QT?
Should I add more bacteria?
More water changes
Anyone else experience color discrepancy with Seachem MultiTest?
