How to add Borax

[smallpooldad]

Chem Geek,

Thank you for the reply. Lots of questions follow.

Firstly something odd is happening. The stains are slowly going away but the usage of Chlorine is going up 2 1/2 ppm loss to 4 ppm now, at a maintenance level of 8 ppm. Could this be due to the fact that the algae is now exposed and chlorine is being used up in the killing process? My concern is that I do not have a borate test kit, do you think that this level as well could be getting used up? I will order on-line this test kit.

I will boost the Chlorine to 40 ppm and hold it there for one week.

Could I use United Chemical's Yellow Treat which contains 88.8% Sodium Bromide, to aid in the destruction of this algae, or is this a bad idea?

I understand that Bromide consumes large quantities of Chlorine but seems to be effective in treating mustard algae. Any idea on how much Chlorine might be used up over the week so I can stock up? And should I maintainance the level back to 40 as it is used up? Is it correct that the filter need to be going 24/7 for the entire process?

What level of nitrates are considered bad for a pool?

Lastly I have Great White 9500 Pool Cleaner that has brushes on it that sweeps the pool is this good enough to do the brushing that is required or would it be better to hand brush with a pole? If so how often, and are the nylon brushes good enough or do I need to get stainless steel brushes?

Looking forward to your reply.
