Does metal gone reduce effectiveness of filter? or perhaps have tendency to promote algae?
I just moved to KY from FL where I had a pool for 12+ years, so I have plenty of experience balancing pools, but are there significant differences in KY? The first thing I realized is that there are higher amounts of metal in the water, hence why I needed to use metal gone to get rid of a green stain on the bottom of a 15k gal fiberglass pool. Its seems that ever since then I cant seem to get the pool stabilized.
It appears the metal gone did its job, but ever since then I have had to shock the pool and re balance almost daily to keep things fresh. I have a 4-cartridge filter replaced 4 months ago, with chlorine tabs in-line, and have cleaned this filter twice now in the past week. Its been about 2 weeks since I used the metal gone. I checked the filter since I kept having the algae and visually it seems OK. We've had allot of rain, so keeping the pH around 7.6 has been a struggle, but still...I know how to keep the pool balanced. I've used about 6 gallons of liquid chlorine since this time, 6 bags of all-in-one, prolly over a gallon of algaecide (the condensed versions, trying different brands), maybe 2 qts of water clarifyer. I've even used bromine just to keep things extra clean. My alkalinity seems OK, but Ill admit I'v been using the test strips that I never did in FL. Acid levels and hardness, again...OK.
The one topic Im starting to be concerned about is phosphate levels. I thought this was a scam, which in 12 years in FL I dont recall using phosphate removers ever. I thought anything less than 500-1000ppm was OK, but the pool place I got my water tested at tries to sell me this every time I go there. I think my level was ~250ppm, which they say it should be no more than 100ppm. I would greatly appreciate any advice folks are willing to give, and thanks in advance for your time!
