30L x 12W x 8D x 4D x 7.48 = 16157 Gallons

In ground pool. Very old. We had it re-plastered some years ago. It has a Pentair clean and clear 320. There is a Polaris vac-sweep 280 brand new I just copied the old set up. There are two motors one for filter and one for Polaris. Both set on timers to run. Filter 8hrs and Polaris 3 hrs. Will be setting it to filter in the evenings need more trippers.

My husband passed away in Feb. Since he maintained the pool I am having to learn about it.
When I started working on the pool in March the sides and steps always appeared to have a gritty substance on them. I had a pool company come over and show me how to clean the filters but the gritty stuff was still there. I drained the pool and pressure washed it and then refilled it. I was tired of trying to fix it and wanted to start fresh. Plus pressure washing is good for me to take out my anger on and lowers blood pressure after talking to husbands Dr's and hospitals. Sort of like Redneck Yoga.

Any help will be greatly appreciated.

Hi, Lisa, and welcome to the Pool Forum!

What kind of test kit did you use to get your numbers above?
What all have you added to the pool thus far? Please list ingredients and not just product names.
What kind and size of filter do you have?
How does the water look?
What is the source of your fill water --- a well or city water?

You have some adjustments to make on the numbers and we can help you do that but first let's get your responses to the questions I asked and then someone here can help you go from that point.

The only immediate problem I see is with your pH, which is too high. Depending on how you're testing, it may be WAY too high, since with many kits a reading of 8.0, doesn't mean it's 8.0, it means it's 8.0 OR HIGHER.

So, add some acid till it's below 8.0, at least a little => see http://pool9.net/ma/

Scaling sides that can be cleaned with a pressure washer AND you have low CH? Sounds like sand algae residue => http://pool9.net/algae-sand

Good luck!

Thank you both for responding so quickly.

Watermom,
I purchased the Taylor K 2000 test kit from the Amazon link through the forum.
The filter is a Pentair clean and clear 320. It has 4 cartridge filters. There are 2 sets of filters one is pentair and the other is filbur. I have been able to clean them and it is running well.
Our water is city. The pool looks good I just need to get the numbers right.

PoolDoc,
I will lower the Ph slowly and then retest water. The scaling sides sounds like my pool but the pictures don't match. Before I pressure washed it if I brushed the sides the water would get very cloudy brownish color and the gritty substance was always on the steps and ladder steps. I have not seen the grit since refilling.

Sounds good.

Taylor K2000 or K2006?

I ordered the K-2006. It has the wheel thing. Did I order the wrong one? I am so numbers challenged anyway and to have to try and fix something using numbers is very difficult. I hope I never lose my notebook full of pool info.

Thanks so much
Lisa

K2006 is the right one. Ignore the book/wheel thing. The kit is great. Those other two things are not so good.
