Hello - we are new pool owners and have been struggling with keeping the water clear...it seems to get out of balance and turns green really quickly. We have been juggling the pool store and blogs and just can't figure it out. As an example, we have started using a test kit - and yesterday everything seemed in a good range yet this morning the pool was a little green... I just went and tested the water again, it's even more green, and got these numbers:
Cl - 3 ppm
Br - 6 ppm
Ph - 7.5
Total chlorine - 5
TA - 160
Total alkalinity seems high though is there a reason the pool is green (i.e. does that prevent the chlorine from working or something?!). It seems we need to lower the TA with muriatic acid - though is that all...and what else are we doing wrong!? it's about a 30,000 gallon pool (a little more), plaster (that the previous owners actually painted themselves so paint chips are coming off...)...pretty shaded area for half of the day (different types of trees) any advice is very much appreciated.
Thank you
