I am very sure Reefroid works. The way I look at these studies are:
1. Is it known that SPS consume bacteria and micro live forms in sea water, that may explain why unfiltered sea water worked the best,
2. I am very sure that Reefroid works. I feed reef roid twice a week and I test alkalinity every day so that I know the daily consumption of alkalinity. My systems show more alkalinity consumption on the days after I fed Reefroid the nights before. These results repeated like a clock work for the past several years.
3. The LPS system shows larger alkalinity consumption than SPS systems, so LPS definitely getting more boosts from Reefroid.
