sulphur reactor by LOUIE P.

Comments: I bought the sulphur and calcium media but used it on a less expensive calcium reactor. It has been running for 4 weeks only and the output has zero nitrates, main tank has 10 mg/L. Yes, I would recommend this product to my friends.

Below Average

S-1502 by John N.

Comments: I tried using the S-1502 for 5 months. It reduced NO3 but not significally. Due to low flow, you must clean the media quite oftern due to algae build up. I converted mine back to the Calcium Reactor. Yes, I would recommend this product to my friends.
