Dosing vitamine C really help too.

Another thing that really help is having a dedicated system for zoa and paly. The less corals are mixed with them the better. People who have zoa and paly dominated tanks usually have much less problem or no problem at all.

Can you recommend a dosage for Vit C?

Thanks :mrgreen:

Definately agree with that!:smile:

I do 5ppm only. And the dosage depends on the product you use (I use sodium ascorbate) and the amount of water in your system. Personally I dose 1/4 teaspoon per day in my 75 gallons with a dosing pump I spread the dose in 12. That give me roughly 5ppm.

I dilute enough vitamine C for a week and then my dosing pump spread that each day in 12 doses.

Here you can get some instructions on dosing and the amount to dose:

Also I buy my sodium ascorbate from www.iherb.com it is cheap and pure buffered vitamine C, so it is not so acid since it is buffered and wont bring your water too acidic.

This is what I use:
