 First Water Change?
Hey All,
When do you suggest I do my first water change? I have a new 40 gallon reef set up. It has 40 # of live rock in it. I am running a sea clone 150 skimmer (getting lots of dark, green, skimate!) and a power filter. Not to mention a bunch of Power heads for water movement.
I put the rock in about 10 days ago, along with 40# of agronite sand...It comes wet, and they say it is live, but I am not sure I buy that theory.
Anyway, My Ammonia levels are dropping off (just about gone), my Nitrite level is low - at the bottom of the scale, and my nitrates are starting to rise. Phosphate levels are negligable. I am getting a little bit of green hair algae on the live rock now.
I am running a 150 watt 10000K MH for about 6 hours a day. 2 65W Actinics for 12 hours a day (overlapping the MH), and Lunar lights for the remaining 12 hours of the day. Tank temp is in the 82-84 degree range. Evaporative cooling is keeping the temperature in check..
My question is when should I start doing changes? I want to keep the nitrate from rising, but do I need to just sit tight for a little while longer until the Nitrites are totally gone? Should I consider putting in a chemi pure bag yet?
One last thing, I am using RO/DI water
Thanks
