  • Watery crap, worst potassium supplement ever By Bob on 8/15/2017

    I went through bottles and bottles to attempt to maintain K levels to atleast 380ppm and this bnever would get above 320ppm, worst potassium supplement ever!!!!!
  • A Must Have! By Matt on 1/10/2017

    I have used many products that claim a lot of things with little results. I use Reef Energy A and B along with Reef Colors A,B,C & D. I have seen the best growth, color and overall better health for my aquarium since using. I would highly recommend!
  • Good but be very careful! By Jay on 2/4/2015

    My soft corals were declining so I tried a Triton ICP test. It showed a big deficiency of potassium and boron. This supplement contains both and is reasonably priced. It is very easy to burn your corals though. I used less than the recommended maximum amount and still had problems. I recommend less than 1/4th of the recommended max dosage per day. The corals now open up daily and look much better.

Product Questions

The dosing states on the bottle add 1 ml for every 20ppm of CA added. Using the BRS two part soda ash and CA solution how may PPM of CA is in 1 ml dose?
Question by: mholzapfel on Jun 1, 2016 10:30:00 PM
Great question!
Instead of dosing per ppm in the solution of Calcium chloride we recommend finding how many PPM Calcum your tank consumes on a daily basis. This will be far more accurate and not have the potential to over dose. In this situation you will measure with a test kit on monday at 9:00 for example and then test again on tuesday at the same time 9:00 am. You calcium will have dropped a certain amount of ppm typically 5-10 PPM. From here you can find out how much of the red sea will need to be added with your correct mixture. Feel free to let us know if you have any further questions!
