Ammonia Spike-PH low...HELP

[john0087]

Hey all,

I had a cleaner shrimp disapear on Tuesday. I checked the params becuase I was worried and the results were

Temp-76
Specific Gravity-1.021
PH-7.4
Ammonia-.25
Nitrite-0
Nitrate-0
Phoshpate-0
Calcuim-240

I did a 15%PWC on Wednesday. I did not locate any remains of the shrimp.

I checked the PH and Ammonia on Thursday AM and everything was good.
I added Kent Liquid Calcium on Friday.

This morning, I did a another water test and the results were the same.

Tank Specs are
37G; 55# LR, 25# LS, 1 Coral Beatuy, 1 Dottyback, 1 Damsel
2 open brain corals and 1 colt coral.

I am going to add some PH buffer and some more liquid Calcium..

Corals look good but the fish are not swimming as normal.

Please help......THANKS

Hi john. How long has your tank been up and running? Also, what kind of salt mix do you use, and how old is it? What was your last addition?

Tank has been running for 8 months. My last fish addition was the Coral Beauty in Dec.

I added the first open brain (green) in Jan, Colt Coral in Februaury and the second open brain about 3 weeks ago.

I think some PWC are in order to get your tank back. This will lower ammonia and raise calcium. Forall of those corals you`ll need higher PH and calcium and lower ammonia.
