Hello there.
Since my pH drops to 7.5-7.6 at night, I'd like to run my fuge (c. racemosa) for 12h a day. The problem is, my tank is starving at zero nitrates and undetectable phosphates already, though I run fuge just for 6 hours a day.
It looks like dosing NO3 and PO4 will allow me to increase fuge photoperiod and thus making my pH a bit higher. Unfortunately, I can't find any saltwater nitrate & phosphate additives in my country. On the other hand, there are plenty of freshwater additives like Aquaforest AF Macro, created specifically to support plants.
So... Is it okay to use them in saltwater? Caulerpa is... a plant to some degree, right?
As for me, AF Macro looks totally fine, since it's effect on K, Mg and Ca is so small:

1 ml in 10 l of aquarium water will raise levels:
N Nitrogen 7,0 mg/l (ppm)
P Phosphorus 0,3 mg/l (ppm)
K Potassium 7,00 mg/l (ppm)
Mg Magnesium 0,9 mg/l (ppm)
Ca Calcium 0,2 mg/l (ppm)
