I currently have some Caulerpa Prolifera in my tank, got it from LFS for nothing so I figured I'd give it a try. As for the filter, I am running the foam media and BioMax that came with it as well as carbon. No skimmer as of yet, what are the benefits? Tank has only been set up for about 3 months (had some cycling issues) but all looks well now. I tested the water yesterday and my reading were PH-8.2, AMM-0, NITRITE-0, NITRATE-20, SG-1.022 and water temp is 78. Would you recommend making a spray wand or just stick with the discharge that's on there now? One last thing, when siphoning out during water changes, should I move my rock to get at hard to reach spots or just let it go?
