Hi all, this looks like a great web site. Im really glad I found it. Good luck to you all.
I live in France and I have an in-ground pool. Capacity is approx 50 cubic metres. I opened the pool later than normal this year as we have had a cool and very wet Spring. Of course, it was green. So I shocked it using a shop bought treatment. I had, at that time a cartridge filter set up. The cartridges were on their last legs. The cost of 2 cartridges (I interchanged them week about) nearly equated to the cost of changing to a sand filter based system, so I changed. The filter ha sregular sand in only. The pool gradually lost its algae green colour but has remained cloudy, but not a milky cloudy. I have tried floculant and shocking it again but I cannot get it clear. I filter it with the sand filter and also a robot which has 2 smallish cartridge filters onboard.
The readings have been weird. Ph this morning was bang on at 7.2 while the TA was at 212. The Chl was at 4.2. How can I get the TA down without losing the Ph level?
Thanks in advance folks.
