Giving up on SPS!

[mrhasan]

I read from a reliable source that on avg, dkH in NSW remains around 3.5meg/L (aprox. 10dKh)

Alongside, I do feed coral snow about twice a week.

Maybe the light and the nutrient is the issue. Whatever that is, SPS are just not worth it to me

Sweet spot is natural sea water, 7.5 to 8 is ideal.

Low nutrient is good for SPS but they do need food then. Especially if you have a weak light, no wonder they are dying in your tank.

with low nutrien you need a good light, good food on regular basis and around 8 kh, no higher.

People think that SPS only live from light alone but in nature there is tons of zooplankton. This is also why SPS grow much better and faster in a mature tank of at least a year old, because by that time zooplankton and all sort of larveas have started to colonize the aquarium.

I feed my SPS every other day with zooplankton food like Fauna marin, reefroid, coral frenzy and I feed Zeovit amino acid and coral vitalizer each day. This makes all the difference in growth and color.
