  1. Blue Life Phosphate RX dosing?

    Just to clarify heres the directions on the container,


    Six drops of Phosphate Control will lower your phosphate by 1 ppm (mg/L) for every 10 gallons (37.9 liters) of water.


    Does that mean 1.0 ppm or .01ppm?


    My phos is testing at .04 on Hanna and I was going to dose 72 drops.

    My tank volume minus rocks and sand is 120 gallons, so 6 drops X 12 = 72 drops to drop my phos by .01?
  2. Bluelife Phosphate Rx

    I am curious if Bluelife Phosphate Rx is a good means of controlling phosphate? I know a few of you guys on here dose this. Would it be a cost effective means?

    Could it replace GFO?

    Also I noticed they only sell it in 1 oz bottles. How many drops would be in a bottle?

    Thanks guys.
  3. Slow growth?

    So I've noticed since I restarted this tank which has been almost exactly a year, slow growth. And I am having trouble with LPS all of a sudden. Most of them are receding. I'm wondering if I am running too much light on my system?
