I've been running it for 13 days. The tank with bryopsis, I'm not seeing any difference in. One of the other tanks that had alot of bubble algae, and cyano I'm seeing differences in. The bubble's are disappearing, and the cyano is getting worse,but not much. I'm not sure where the cyano came from but my urchin has been missing in action since just before the cyano showed up. I'd much rather deal with cyano than all the bubble algae so I'm happy. I don't test for phos or nitrates. I've got so much algae in these tanks nothing ever shows up, so I quit wasting my time.
The one major upside I'm seeing is polyp extension. My sps always had a bit of extension, but now it is unreal. A couple of the SPS now have noticeable growth on them. I've got 3 non photosynthetic gorgonians that really haven't ever grown, sometimes they're open most of the time they aren't. In the last week their polyps have been open full time, and new branches are sprouting everywhere. I haven't seen any improvement in the areas I was looking for help in, but the side effects are worth it to me.
I built my own reactors. I used 700 ml pop bottles, cut the bottoms off, covered them with plastic window screens secured with rubber bands. A hole was drilled in the cap so a power head (MJ1200 and Rio 600) friction fit through the hole. To keep the pellets out of the pump a small piece of screen was put over the threads and the cap screwed back on. Works really well. Cost was about twelve cents and 3 minutes of work.
