Caridina GH+ - Establishes Mineral Balance in Purified (RO/DI) and Soft Water
I love the concept of this product, but the execution is a complete miss. Can't shake well enough because of the leaky pump top. Solution is so weak it takes 5 to 10 times to recommended dosage to raise even 1 degree of GH in a 5 gallon tank.
I really wanted this to be a good/easy product for my crystal red shrimp... it's just not what it's advertised to be on the bottle. 1 pump should bring 20gal rodi water to 1dGH as per the bottles instructions. I do a 2gal. water change every 2 weeks, it took 4 pumps to get 3gallons (I always premix a little extra) to 3dGH. Plus to get the dGH any higher I would be pushing the TDS too high leaving no room for frets. Maybe I'm seriously overlooking something but the reviews for the Gh/Kh version read almost the same. Sorry, I wanted it to be good too, but it just doesn't compare to Salty Shrimp. P.s. if you do buy this just throw the pump top away and use a pipette, the pump is leaky and not too accurate.
