Are you using Reef Crystals?
I've read some things about reef crystals recently containing superflous things that would aid in algae growth.
I use this salt, and I think Im going to change soon. It tends to add Phosphates to my syestem I think.

I would have to say that is your problem. Phosphates, nitrates and silicates are elements that naturally occur in water, and it is not unusual for some tap water sources to contain high concentrations of these chemical elements. If these are not removed from the water before using it, you are just adding more of the unwanted elements that give rise to all types of algae blooms in saltwater systems, and that often contribute to persistant problems with higher than normal readings of these chemicals when testing the aquarium water. Also, Copper and iron are particularly detrimental to reef animals, and these or other metals can often be present in tap water as well. I think that you will see this clear up quickly once you start using your RO/DI water. Do a very large water change or a couple small ones per week. Good luck.John Kh":3t8j8zhu said:I use TAP water, I know this is not recommended but waiting for the RO/Di device to come. I change water weekly and I use Tetra Marine Salt. I am changing this too once the store get the new SALT collection. My water parameter? I relly do not know exactly. It has been a while since I last checked them!! The tank is like 5 or 6 months old.
