Hi guys! My toadstool leather looks extremely unhappy (at least today some tentacles are out but they weren't for a few days), cabbage leather has looked better (often these days shiny/dark and smaller), pink devil zoas have been staying closed and dying off, GSP have looked better, frogspawn smaller/less inflated, some of the paly's are less green and edges curled under, and my SPS's are dead/dying. AND I can't find my sexy anemone shrimp yesterday or today, so he's either dead or moved, but he'd been in the same area for weeks. Some of this started a month or so ago, but the major issues have been in the last 1-2 weeks (the leathers and SPS's).
Today's Salifert testing:
NO3 10
PO4 0.75
KH 11.2
pH 8.2
MG2+ 1200 (I've ordered some Mg to supplement)
CA2+ 375
SG 1.025
We have chaeto, a new skimmer, a new sump with two Skimz mesh socks, and ATO, two Hydra 26 lights over our 120 gal aquarium with 28? gal sump. The ONLY thing that's really changed in last month is we've started using NoPox but as you can see, Nitrates/phosphates are just now down to a decent level and things seem to be getting worse instead of better. And we are using SeaChem Reef Builder in the top off water to raise/maintain alkalinity and it's working great. We used to run NO3 20-25 (but we didn't have the SPS's) and PO4 0-0.2 but we got up to a consistent NO3 50 and PO4 started climbing to 1.0 so that's when we started dosing about 10-12 ml of NoPox daily and cut our feeding. Otherwise, we have got a Kessil H380 to grow the chaeto and cut our food in half (frozen mysis, Marine Cuisine, and LRS rotated daily and a sheet of nori once a week for the hippo tang and lawnmower blenny.).
Ideas? Could it be the NoPox? Could the low Mg affect it this much?
Thanks!
