If you are talking about the square style reactors then yes I have had one. The larger of the two works better than the small one. I was able to keep my calcium up in a 75 gallon mixed reef. I can't tell you weather its better or worst than any other one on the market. I can tell you that getting replacement parts can be very hard. It uses a modified powerhead made to fit into the top of the unit along with other parts that you could normally replace with simular items.
