Problem: my nitrates have slowly fallen to zero (7.8 on 4/21 to 0.0 on 5/11 on the Hanna checker and confirmed with API test) while phosphates have crept from 0.07 to 0.23 over the same timeframe.
50 gallon tank plus sump, about 4 months old now. I have three fish (fire fish, diamond goby, carpenter's wrasse) along with a cleaner shrimp and a good complement of snails and hermits. Two corals (hammer frag that seems to be growing well and a favites frag). I've been running a chaeto refugium for almost two months. When the nitrates hit 0 about 4 days ago, I removed all but a tiny piece of the chaeto. Nitrates are still 0 today and phosphate has increased a little.
I work long hours so I have an Eheim feeder giving TDO Chroma Boost twice a day. I feed frozen mysis and brine shrimp whenever I'm home. I use a filter sock and a Deltec 400i skimmer.
I'm dosing All For Reef to maintain alk and Ca levels.
I've been fighting diatoms for a while but they seem to be lessening a bit. Scared of getting dinos or cyano or something with no nutrients around. Or starving the corals.
Current parameters:
Salinity: 34 PSU
KH: 8.4
Ca: 440
Nitrate: 0
Mg: 1440
Ammonia: 0
Nitrite: 0
pH: 7.9 - 8.1 on Seneye
Please help!
