Okay, so I know I have posted this same post two weeks ago, but I am still having Ammonia issues! I have done water changes, I have checked for dead fish, and I have checked for anything else that maybe causing the issue and I haven't been able to determine what is going on! I really need some help with this... Numbers last few days - Ammonia is testing at 0.25 to 1.00 I have been dosing with Prime ever other day. Nitrate - 0.05 Nitrite - 0 CA 360 - 400 PH 7.8 to 8.2 Phospate - 0.25 Salinity - 1.024 Changes - None New RODI unit - I have test the water and there isn't any ammonia in the RODI water Protein Skimmer working during the day only - off at night due the noise - Could this be the problem?? Because water does sit in the unit when its off at night, then turned back on at during the day? No fish have died I haven't seen many snails tho Hermit crabs alive Bubble coral alive and out Anemone alive and bubbled I have had my water checked at the LFS, and yes there is ammonia. EQUIPMENT Reef Octopus 1ooo classic HOB Aqua Clear - Medical Matrix, Purigen, and Sponge. I can't figure out whats going on! This has been going on now for three week! I have only had the Protein Skimmer and RODI for three weeks as well. I don't know what to do!
