help with test results

[rickyislandgirl]

Thanks in advance...

TA 220
CH 90
FC 3
CC 0.5
PH 7.5
CL 5-10
CYA 20+ faint

Well water. Adding CYA in sock. Pool is clear green can see bottom. When I add bleach it gets greener pretty sure in need a sequestrant. What to do next?

Metal sequestrant seems to be indicated, yes.

You are using one of the recommended test kits, right?

That TA does look like it needs to come down some, check pool school for how.

In addition, suggest you keep a close eye on that FC and CYA. Your chlorine (FC and CC) are right on the bubble of needing help. Your CYA is low based on your Recommended Level of 30-50 (see link below), so your free chlorine is probably getting used-up real fast in the sun. Since your pool has green in it (even though it's clear), that's an indication you have algae and need to do our SLAM process (link in sig below). All of this is still based on the fact we don't know what test kit you are using to get your numbers. If you don't have one of the TFP recommended kits, you really need to get one (i.e. TF-100 link below).

Thanks I do have the TF-100 test kit.
1. Add sequestrant
2. Acid and aeration
3. Slam, keep eye on FC & CYA

What do you think ?

Thank you

Do you have daily chlorine test and add results? Do you see a trend with increasing daily chlorine consumption? You could Perform the Overnight FC Loss Test (OCLT) to check for organic matter.
