Using a webcam throughout the night on time lapse to look for more pests. Bought a butterfly fish to eat pests. Has not munched on corals yet!

Params:
Salinity @ 1.026
Ca 440
DKH 9.8
Mg 1600 (falling back into line from accidental OD)
Nitrate/ite and phosphates undetectable

For most tests I use Hanna calorimeter

I have algae in the refugium, running a phosphate reactor and an oversized skimmer for my 75g display (25g sump)

Should I disconnect the phosphate reactor and run the skimmer intermittently on a timer? I understand zoas/palys need a trace of PO4 and nitrates.

Tank is lightly stocked. SPS are coloring nicely, most LPS look good but my orange hammer could look better.Torches, Gonipora and photosynthetic gorg look good too.

trust me you want no phosphates with zoas and palys, this has been my experience anyways , for the few that prob do like phosphates the majority dont.

nitrates now i find different , they like a steady amount so no up and down all the time, but not too much either. what you use for nitrates prob depends on what other corals you have , in a zoa only tank i wouldnt mind 20 or under.

with other corals maybe 5 or less.


feed your zoas and palys...they will grow fast if theres always food available throughout different times of the day and night if you can
