I have a 55G reef.
NO I believe is Normal Output and it's something like 15W per bulb. Normally those standard canopies have one 15W bulb each so you have 30W to start with.
and PowerCompact is a little confusing to me. I have PC
's that run at 4x65W. VHOs I think run at about 30 - 40W per bulb? I may be wrong. I am not a VHO
kind of guy. Metal Halide can go really high per bulb. A common one would be 170 some odd watts.
In terms of laced rocks, did you convert from fresh to salt or something? Lace rocks are OK. But reefers tend to go LR
way in order to give a certain natural look. Plus, you get those critters/hitchhickers as bonus.
In terms of whether or not it's a high or low water flow doesn't necessarily mean how many powerheads. In a setup with a few powerheads in them, there are high flow areas and there are dead spots or low water flow areas. So when you see "moderate to low water flow", it basically means place the coral at a certain area wherein water is not directed to it.
I have a 400gph PH, a 175 gph
ph, and a 270 gph
powerhead. Then I have a prizm skimmer and two HOB
Powerfilter 60. My "turnover" rate is about 19 times per hour. That means I turnover the "estimated" volume of my water 19 times per hour. Considering that I have rocks and sand in there, I may already be turning over about 23 - 24 times per hour.
Finally, GSP's are cool. But I think you should at least have about 3 - 4 watts per gallon. That's just an estimate. We're not even talking about light color temperature and stuff yet. That's a little too complex. but give or take 3 - 4 watts per gallon is decent and safe.
If you want to go reef, might as well spend money on lights. Look at the Orbit brand. That's what I got. Some may say Coralife brand. It's different strokes for different folks. I enjoy my Orbit 4x65W daylight/actinic with moonlights. They're only about $190 nowadays. It isn't that bad.
PS: get a good skimmer.
Good luck and welcome
