    High Pump and Filter Pressure

    Hi everone,

    so i finished the install of my 15x30 54 inch pool. It's hard plumbed with 1.5 inch pipe. Elements are a hayward 1HP pump, Hayward C9002 cartridge filter and hayward cl200 Chlorinator. I recently have the pump pressure running up to 24 PSI which appears to be high and the return flow not as strong. Two days ago, I swapped out filters for my spare, bled and re started. The system ran at 16 PSI the whole day and had much better return. A few days later the pressure climbed steadily and is back at 24 PSI with weaker return flow again. Anyone have any clues or similar issue and can help me troubleshoot the issue? Attached is the Pic of my combination

    Could it be you have something growing in your pool? Your description suggests this.

    Can you post a full set of numbers, including an OCLT?

    No, water is clear, water test was fine just added some shock last week and the FC level is good. Only CYA is low.

    Your water can be clear, and still have something growing in it. Do you have one of the recommended test kits? Your use of the word shock makes me wonder.

    Please post the numbers.

    The basic premise to having your own kit is accuracy in testing. We have found that pool store testing is quite frequently off by quite a bit, especially on the CYA test.

    You can't do a proper Overnight Chlorine Loss Test using pool store testing. The OCLT will tell you if there is a problem that you can't see yet.

    You best value is the TF-100 from http://tftestkits.net/splash-page.html

    I'll also make the suggestion that you read more in Pool School concerning algae.
