When I started my tank, I got a little gung ho and bought a few things that I'm not ending up needing. One being the Red Sea Care Supplements (A-D). My tank doesn't have that high of a demand since I don't have many SPS. The total price online at Marine Depot is $44. I'll sell all 4 bottles for $30, never used. Consists of: Red Sea Reef Coral Colors A (Halogens Supplement I, Br, F) promotes pink                  Red Sea Reef Colors B (K + Trace Elements) promotes red                  Red Sea Reef Colors C (Fe + Complementary Metals) promotes green                  Red Sea Reef Colors D (Bioactive Trace Elements) promotes purple, blue http://www.marinedepot.com/Red_Sea-Salt ... AD-ct.html I can bring them to the meeting next Saturday or can arrange another option if needed. I also have an Ecotech Vortech Battery Back up which I'm looking to sell for $130. Have a permanent back-up generator so no longer needed. Retails for $170.
