Would appreciate some advice.
Was a new pool owner last year, and completely lost the battle with the water. It started to cloud, I continued to shock, but got nowhere. See previous posts for detail.
Completely drained pool in the spring, and there was a huge amount of what appeared to be sand at the botom. Had pool cleaned, and filter serviced, and refilled the pool.
3 weeks in, I notice that there was 'sand' at the bottom of the pool. I vacuumed it, and it was like new.
4 days later (yesterday) there was a worse covering than before, so I vacuumed again.
This morning, yet another covering.
I thought it might be sand but, after reading many posts on here, I wonder if it is the mustard algae. Have attached a nylon stocking (is this what you mean by 'nylon sock'? - we use slightly different terminology over here in the UK, and my wife is convinced that references to nylon sock do in fact mean stocking). I vacuumed initially running through the filter, but it appeared, at least to me, as if the sand/algae was coming straight through the stocking.
The sand/algae is all over the bottom of the pool, and not just around the outlet, this leads me to believe that it is algae rather than sand. When brushed, it tends to cloud up rather than move.
Any thoughts on my options from here? Will flocculent help? What about Jolly Jell? I tried the latter last year, without any joy at all. (sorry for the pun!)
Pool was shocked last year for lengthy periods, to almost industrial levels, hence I am at a complete loss as to where to go from here.
Any help would be appreciated, thanks in advance.
