TF-100 Test Results

[tiny_torpedo]

Still struggling to get my pH down. It reads the highest the test goes every time (8.2). Any help would be appreciated. Just had a new Salt Cell installed about 3 days ago, so not sure if that has anything to do with it. Here are my latest results from this evening.

pH=8.2
FC=17.5
CC=1
TC=18.5
CH=450
TA=120
CYA=80

You need to use muriatic acid to lower ph and TA.

With FC above 10, the pH test is unreliable. Let your FC drift down to 10 or less and check the pH again.

What is your salt level?
How does your water look?
Why is your FC so high? were you SLAMming?

With a SWCG, you might want to work on getting your TA down in the 60-ish range to help keep your pH a bit more stable. Of course, do this only after you've tweak all your other numbers.

Salt level is at 3200 ppm. Have not slammed or anything like that. Salt cell is running at 85%. Water is crystal clear.

How do I let my FC drift down?

Turn the SWG down or even off.

And test to see how much it drops - daily. Once it's 10 or below, test and adjust pH.

Oh, how many hours per day is the pump running?
Please add your pump make and model number to your signature (filter model number and SWCG model too).
