Yep Phosphates. You have algae because you could be feeding your tank to much. Or you may not have enough flow in your tank to water moving. Do you have a sand bed? Cleanup crew?
Welcome to the club!!!
Can you tell us what you plan on keeping in your tank? 400 to 450 seems about right for most corals,clams etc. Post those pictures soon!!! Check to make sure your tests are correct.
One thing to remember is the cost factor. If you get a expensive piece and it dies in your tank money waisted. Better to wait and increase the chances for survival rate. I know its really hard to wait. Your patience will be rewarded.
I would wait for at least 4-6 months. If you want to add things like clams I would wait at least 8 months to a year. This however depends on how often you do water changes and what your test readings are especially in ph and nitrates and calcium levels.
Question who would you like to see in the superbowl? I would like to see Arizona make it. Everyone doubted them yesterday when they played the panthers yesterday.
