Hey all,
First post on this great website. I have been a covert to the TFP system but I have this ongoing problem (or maybe it isn’t one).
I have a small (30k litre) fibreglass SWC pool in Sydney Australia and I keep getting deposits in the bottom of the pool that looks brown and puff away when touched (see attached photos).
I did an overnight loss test and FC dropped less that 1.
Other stats:
FC 6 (I am letting it drift to 3 as per SWC recommendations)
PH 7.6
TA 75
CH 350
CYA 70
BOR 23 (waiting for more boric acid to arrive)
I have previously taken FC up to mustard shock levels for 24 hours (with lower CYA), lots of brushing but it came back. I have no automatic pool cleaner and manually clean once a week.
Is this actually an algae problem or just normal dirt /pollen that I should except and needs to be cleaned. I am thinking it’s easier to see dirt/pollen in a fibreglass blue pool.
Thanks for your help!
