Hi fellow zeoaddicts,
I reached a stage where I need to “fine tune” the system. My tank is 9 months old, 500 L/130 gals net volume, 960 Watts lighting, high water movement, heavy skimming, medium coral density, light-medium fish load.
Main water parameters are as follows: 34‰ salinity, 7,4° KH, 410 mg/L Ca++, NO3 undetectable, PO4 are very steady at 0.01 mg/L (Hanna colorimeter).
Doses: 5 drops bak, 5 drops food once a week, total of 0.18 ml start2/day (yes, only 0.18 ml divided into 4 doses/day with a peristaltic pump), 5 drops AAHC day, 3 drops PIF twice a week. I weekly change 5% of the water.
Colors are fine but someway too “pastel-light” and not very saturated. I would like to work a little bit on this. I’m now dosing 5 drops AAHC daily to try to improve colors, but I only obtained some cianos on the sand, so I’m gonna reduce it again. I have a pink Stylophora that is very fluorescent but light in intensity, an efflo that lost his light blue ridge becoming light brown, a blue echinata that is light blue instead of the original deep blue.
I just ordered PCV (a.k.a. Coral Vitalizer) maybe it could help. Should I try to reduce zeofood7 and increase zeostart2? Should I try with some macro-elements?
My guess is that water is too nutrient poor and corals lack a source of proteins to build up pigments. Note that my skimmer is VERY powerful.
Any ideas?
