Corals are happy

Comments: I bought this item along with Zeo food 7 to jump start my Bio pellet reactor and I am very happy with water clarity and my coral polyp extension. I am not sure if this is the sole reason for the improvement or not but my phosphates and nitrates are way down now after only 2 weeks. Highly recommended.

Comments: I recently purchased Zeobak, Coral Vitalizer, Zeofood 7 and Pohl's Xtra. I thought that my corals were happy prior to adding these additives, but I definitly see more colorful and fuller corals-both LPS and SPS. I don't know if this postive outcome is due soley to Korallen-Zucht's prodcuts or because they work well with the Tropic Marin additives I also use. In any case, I will continue to purchase Korallen products in the future and would definelty recommend these products to you!!
