Re: When To Add Protein Skimmer ??
I would add one asap, IMO. Usually skimmers have a break in period of about 1-2 weeks or so. By the time your skimmer is reved up and ready to go, you will be almost done with your cycle.
I use the Aqua C with a MJ/1200 on my 55g reef tank. It does a good job of skimming for my tank, but, I wouldnt recommend it on anything bigger than a 75g. You could def. run 2 of them. Hang ons work better with smaller setups, IMO. Is running a sump/refugium a possibility? For the price of 2 Aqua C hang ons, you could run a 20-30g sump with a good in-sump skimmer. Maybe a bit more, depends where you get the supplies from. Just a thought.
Hope that helps,
