Calcium help

[igadget56]

Don't know what to do next. I have a 125 gallon with 20 gallon sump 225 pounds of live rock and anenome that came with the rock from an existing tank. One rock has a polyp on it and it looks healthy. Tank has been up about five months, and never really cycled. I took about30 gallons of water with the live rock. Ammonia and nitrite have always been on 0. Nitrates are 20 ppm.I have six small fish and no other coral. Also a cleanup crew from Foster and Smith. Coraline algae growing on the rocks. There was some growing on the back of the tank but now that is green. I got a new evolution LED light hanging over the tank about 18".I have on a timer 10 hours a day. I will be getting another when funds permit. I did 2 15 gallon water changes in the last week. Yes I use RO/DI water, but not on the initial fill up.

I thought after a week I would have much better readings. I don't know what to do, should I just continue for a while or can I up the dosages.

Everything looks cool to me. I think that all this stems from the Salt your using. Which is? Check your parameters out 24hrs before you add this water to the tank. At this time, before hand, you can get this new water to where it needs to be, then put it in to the tank. For now, I would dose per recommendations.

When you say, get this new water to where it needs to be, to you mean by adding the magnesium and 2 part?
How much should I do at one time? I use reef crystals. Thank you.

When setting up for a water change, you set the water parameters where they should be beofre you put it in the DT. Let all this dissolve for 24hrs, and then your set for WC. Reef Crystals?? And it does not get you to at least 400 in the CA department? Sounds more like Instant Ocean than the good stuff. Ouch
