Thanks guys. Im going mix reef. But probably do more SPS. The equipment list is long and its going to take time to get it all together. Right now im running a sca 301. Good for 65 gallon. But its what i had on hand. I have 1 wp25 looking to get another one soon or maybe a rw8. I have been keeping a reef for 5 years now but never got in to the dosing part of it. I have reading up on it and im almost ready. I really need an sps guy to talk to about setup.
