Hello everyone,
I have had my RSR 900 (240g) for almost 2 years. I have had coral for about 1.5 years. I have added fish as I have gone along, but I wouldn't say anything outside the norm.
No matter what I do, I always seem to be stuck at 0ppm Nitrates and close to or around .1ppm Phosphate. I've tried increasing feeding, liquid nitrate droppers, etc. I wouldn't be concerned, but the left side of my tank - all of the corals are doing very bad. I have a mix of LPS and soft.
On left side, I've lost - a large Euphyllia colony. A lobo. Several acans. Even my GSP has closed up at points, although it continues to survive. My mushroom is the only surviving, healthy coral on that side.
On the right side, in general my corals are doing well - a frogspawn, several mushrooms, leather coral, and a few plates.
To my knowledge, nothing has broken or significantly changed.
My parameters are:
8.01 dKH (Apex)
462 Ca (Apex)
1235 Mg (Apex) - I realize this is a little low, but I've been trying to dose it, and it basically hovers around this. I've tried SeaChem Mg and Aragonite C.
.1 Phos (Hanna)
0.0 Nitrate (Hanna). Occasionally, I can get it to 1.1 if I put a lot of "effort" into it
1.025/6 salinity
78-79 temp constant
8.2 pH
I've gone through cycles of hair algae, cyano, etc. I really would appreciate any help - I don't understand it!
My urchins and two shrimp have been doing fine. I did recently lose 1 of my new Anthias, but otherwise the stocking has been good: Foxface, Blue Tang, 2x PJ Cardinal, 2x Clownfish, Tomini Tang, 2x Anthias, 2x Urchin, 1 Fire Shrimp, 1 Skunk Cleaner.
I can attach pictures but it's sort of difficulty - basically one head at a time dies from my torch, euphyllia, lobo until they're gone. Right side seems significantly less affected. Problem has been going on for about 3 months.
Today I moved my powerheads (MP40) which are both on left side (and always have been). They were moved about 2-3 months ago, but that was because I started noticing this problem to begin with.
Thank you so much for any advice!
