    This does not mean it only affects this site, It now means that billions of images across the Web now display an error message instead of the image in question. :(

    I bought GH Booster from Green Leaf Aquariums. The product page on their website calls it as 'Ultimate GH Booster', but the label on the actual box says just 'GH Booster'.

    In Rotala nutrient dosing calculator, there is a 'GLA GH Booster' that can be selected under DIY option and then there is a 'GLA Ultimate GH Booster' that can be selected under Premixed option.

    I tried seeing how much 20 gm will add to 75 gallons of water under both the selections, but I am getting extremely different values of Ca and Mg between both:

    1. DIY option --> GLA GH Booster selection --> Dry dosing --> Result of my dose --> 20 gm --> will add 6 ppm Ca and 2 ppm Mg
    2. Premixed option --> GLA Ultimate GH Booster selection --> Dry dosing --> Result of my dose --> 20 gm --> will add 2000+ ppm Ca and 2000+ ppm Mg

    Which option and selection I need to use for my need?

    Note: I find the below from a past post on this forum. If I go with Premixed option as Fablau seems to indicate, it does not seem to align with the response from GLA

    I sent a mail to GLA. This is their reply

    To raise general hardness (GH) by 1 meq/L (3 dH), add 16 g (1 tbsp) per every 80 L (20 gal) of aquarium water. Dosage is based on use of DI or RO water. For other water, measure hardness (GH) first, then add according to need. Plant preferences vary; a general quide is 1-2 meq/L (3-6 dH) or match existing or target carbonate hardness (KH), ideally 1–2 meq/L (3–6 dKH).
    Can we add GLA Ultimate GH Booster. I believe its the same makeup as Seachem Equilibrium but I was really confused when I started looking for the dosage until I finally found some forum saying its same as Equiibrium. Will save another newbie some time.

    [Posted by Fablau] Added. Please, try it and let me know if it works. It is under the "Premixed" section.
