Hi. Ive been tackling this problem for maybe a month now. I run a 27gallon AIO tank with 2 osce clownfish, a 6 line wrasse and a hermit crab. I have a frag of GSP, a Yuma Mushroom, a Hammer coral and a frag of Zoanthids. For the time being, my hammer coral and my zoanthid seemingly to be quite unhappy. My hammer has retracted (not fully, there are still the heads inflated but the "tentacles" are retracted) and my zoanthids seem to retract since today.
I feed my fish pellet food, zooplanktos-s and mysis shrimp (I change their diet per day). I feed once a day and keep the volume of food on the low.
I run a mechanical filter (filter floss), Phosguard, ROWAPHOS GFO, some bio balls, a bag of carbon and a bubble magus QQ protein skimmer.
I use Cove salt.
From the last water change I did, I tested all the parameters below.
Salinity : 1.024
Ammonia : 0
Nitrite : 0
Nitrate : 0 - undetectable
Phosphate : 0.5-1 (have been hovering in these values since last month I checked, even after a 10-20% waterchange)
Alkalinity : 6.7-8 (it reaches 6.7 right before the water change and is at 8 right after the water change).
I also use an Aqua Knight spectra light for my corals. I do water change weekly on saturdays.
How can I lower my Phosphate levels? cause it seems weird to have 0 nitrates but sky high phosphates.
I added the GFO last 2 weeks and it seems to have little to no effect on the chemistry.
Also, I only turn on my skimmer at night because I aim to increase the Nitrates in my tank to detectable levels.
Ive heard of Lanthanum Chloride but I have no luck in finding the product here in my area (Sarawak, Malaysia).
Ive heard also of carbon dosing (using sugar, vodka or vinegar or No Pox).
Which technique do you guys think is okay?
