linen said:TDS must be drained/refilled, Iron can be sequestered with a chemical (though a drain and refill with iron free water is also an option). Your copper level should be fine.
He could justify charging a lot more for a drain/refill, then adding a sequestrant.
Your filter size is a bit small at 84 sq. ft. so it will require more frequent cleaning, which of course would be quite often while clearing a pool. I can't imagine having to clean all 14 everyday
If you ever get a new filter we would recommend a minimum of 200 sq. ft. cartridge filter.
We drain and refill ourselves. Even if it had to be totally emptied, we wuld do that. We're in the country. Drain to the brush on our property line that borders a farm field. Opposite side of the well and septic. Half drains for winter have never been destructive, accept maybe to the weeds which is fine.
If we had to do a total drain, it would be next year, for a new liner. He won't get our business for that. After taking two months with the motor, then making me wait another week for filters that were ordered in April, I won't be buying ANYTHING from him. HE doesn't know that, yet.
So, he profits nothing, really from any advice he gives me at this point.
As it stands, the liner gets replaced next year, with a new filter system OR we fill it in and make a nice patio.
We can not do it this year. Believe me, I do not enjoy the frequency at which I have to rinse the cartridges.
For the moment. My plan is to replace a current cartridge with the extra new one and see if one of those cleans up with something stronger than hosing.
