polyp labs ONE-anyone tried?

[kellerexpress]

I recently came across this product from polyp labs called ONE, its an all-in-one dosing product that is supposed to keep your calcium, alkalinity, and mag all in check, like a two-part, but simplified in one product. Seems too good to be true, has anyone used this product?

What it claims to do it can't do. Why do you think you need to be dosing? What are your water parameters and livestock list?

 

No product in a single bottle can provide both calcium and alkalinity (carbonate/bicarbonate) because calcium carbonate would precipitate out until either calcium or carbonate is used up. Kalkwasser is an exception, but it is made of calcium hydroxide, which stays in solution. This is why two-part solutions are so popular.
