I bought the HTH kit last night and tested this morning. I have a really hard time reading the color differences on the yellow so I'm not sure how accurate I am. They just all kind of look the same to me. I had my 8 year old help for a second opinion...

CL 5 (however I did a strip too just to double check myself at I only got 2 on that, I'm not sure what that means)

Ph 8.2

Alk 190

Hardness 390

CYA 40

I have been using liquid sodium hypochlorite 10% (2gallons every week to shock) and trichlor 92.4% pucks floating.

That is all I had been putting in for a few weeks.

The one pool store gave me some algae stuff (Biogauard copper 3.3%) and I put a bottle of that in yesterday. It's supposed to stay in for 24 hours then I'm supposed to vaccum. Today the pool looks about the same if not a little bit cloudy which I'm assuming is from the Biogaurd.

As far as it the question about it being just sand.....I'm not sure it could be. I initially thought that is what it was honestly. I haven't had this problem until recently and I've not damaged the filter. Could a lateral go bad if nothing has happened to it? After I backwashed the return water was clear so that is another reason I thought it probably wasn't sand.....I really don't know though.

I'll go fill out those charts. I really appreciate any help! Thank you so
much!

How do I find my PF user ID. It's required for the chart and I can't find it. I tried to click on profile at the top and got a message that says I don't have permission.
