How much borax to add

[CrisL]

If you google proteam supreme, you will find some stuff related to the use of tetraborate (proteam is a pool additive very similar to borax, but much more expensive) and its use as an algaecide. Adding large amounts apparently works to help keep the water clear. The makers do have testing kits to see how much is in the pool.

Many people here use borax because it raises ph without also raising alkalinity much and it appears to help stabilize ph - once the ph is where you want it, it stays there better. Borax generally comes in one size box (three pounds?) The amount you use as a ph increaser will never get you to the amounts recommended for algacidal properties, so if ph increasing is what you want, you really do not have to measure the amount in the pool. Use about 1/2 box, wait, test and use some more based on the results you got with 1/2 box.

Proteam Supreme is *like* borax, the same way BioLab's Balance Pak 100 is *like* baking soda.

. . . Proteam Supreme *IS* borax!

The algicidal properties are unproven, and I've never seen any evidence that borax makes the water clearer. But, it won't precipitate calcium carbonate (making it cloudy) the way baking soda can, if the pH and calcium levels are high.
