Please help us out. We have had out 120 tank going since July last year. Levels are good. We have a sump with refugium and protein skimmer. Live rock and sand. We measure our levels weekly. I test salinity every other day and add RO water when necessary. Our healthy yellow tang Wolley was just found dead this morning. We feed mysis, brine shrimp and nori sheet. Our corals are not happy. We just can't figure out what we are doing wrong. We could use your experience and help please!
Tank inhabitants:
1 six line wrasse
1 oscillaris clown fish
1 bangaii cardinal
1 green frogs pawn frag (no full extension)
1 GSP frag
1 blastomussa
2 zoanthid frags (closed)
1 montipora plate (browned out)
1 aussie dendrophyllia (recovering nicely)
Current levels:
Salinity questions 1. 025
pH 8
Ammonia 0ppm
Nitrate 20ppm
Phosphate 0ppm
Calcium 520ppm
(I will measure for alkalinity and magnesium tonight and update)
