- Tank #1 Specific grav=1.023, Alkalinity=High 2.9-3.6, Ph=8.2, Amonia=0.0 ppm, Nitrate=20, Nitrite=0.25 water temp=78-80 C (85g FOWLR, 4" sand bed w/coral substrate base, UV sterlizer, Remora Pro Protien Skimmer, 100g Canister filter, Korella 3 flow, sandstone areo)
Thought it maybe the PetCo so I went to my LFS which is where I get the majority of my fish and had them select a nice/active medium Niger Trigger which I added and acclimated in similar manner. He too died within 36hrs. That was 2 weeks ago.
On Monday I did a 20 gal water change with perfect water parameters of clean salt mix (no contamination) of the tank and even cleaned the sand bed as well. Test results tank #1 are above. Again fish (Asfur, P tang, Clown tang, Marron clownfish) were doing wel l.
Today as a test I then got 2 small green chromis & 2 small damsels (which are usually nearly invincible) and added them to the tank. 2 of 4 died within hours.
Once again all other main fish (Asfur, P tang, Clown tang, Marron clownfish, 2 sand sifting starfish) were all okay/feeding and swimming around as before.
Added coral banded shrimp to tank #2 today; which is my most active tank now containing a Queen/blue angel (juvenile), med foxface, med yellow tang, clarki clownfish, percula clown, coral beauty, and 3 chomis green and 1 damsel, and 3 sand sifting starfish. He died within a few hours.
Tank #2 Specific grav=1.026, Alkalinity=High 2.9-3.6, Ph=8.6, Amonia=1.0 ppm, Nitrate=20, Nitrite=0.0 water temp=78-80 C (55g FOWLR, water ionizer, Hang on bag filter/Protien Skimmer, 100g Canister filter, sandstone areo, 3" sand/coral substrate)
HELP....is it me; my tank, my water; my test kit; my sand? Do I need a new test kit, another water change, is there something I am NOT testing and missing? I've heard about 4 different explanations from LFS foks that I have no idea what to do now. :-(
