My pool is about 25,000 gallons, inground, white plaster, DE filter.

Here are my numbers based on PS234 (except for TDS #).
FC: 15 (shocking cause I found a dead mouse in the skimmer basket)
CC: 0
TC: 15
CYA: between 40-45
TA: 120
CH: 220
TDS: 1200 (according to pool store)
PH: 7.4

My pool is clear but when it's dark and the lights are on I can see white flecks of stuff floating by.

Pool store told me it was TDS and that I needed to oxidize weekly to help remove some and keep it under control. I didn't buy any because I couldn't find what the main ingredient was and I also wanted to check here first.


Only chemicals I've used this year are bleach, muratic acid, cal hypo (sock in swim - only since I could use the calcium), and I do put polyquat 60% in once a week to prevent algae. My chlorine is constantly between 4 and 7 on a normal basis.

Anyone have any thoughts on what I can do to get the water so when the lights are on nothing appears to be floating in it?


Thanks for any assistance.
