I guess the words "low" "moderate" and "high" light mean different things for different people. I have a 130 watt fixture similar to yours (one 65 watt is 50/50, the other is actinic) over my 20 gallon reef and I consider it "moderate" light. But you should be able to keep lots of corals (leathers, zoos, mushrooms, lps
, softies) without a problem.
I've been using Rena canister filters for about 4 yrs and I like them a lot, but I've never had Eheim.
O and I read somewhere that the prefered way to start a tank is the lr
first then the ls
so that the lr
is on the glass bottom (or eggcrate or whatever) and stable. But I guess it really doesnt matter, just make sure it's stable.
