Water Issue

[kpromero]

Hey all, can a pool pump be too much for a sand filter and not clean properly? Purchased a 1.5HP Superflo and had a 300 lb sand filter and for some reason I cannot get water clear and has a light green tint to it. All my numbers are correct and I have been trying to keep chlorine level high to see if it will help but getting nothing.

K,

If you run your new pump at full speed all the time.. maybe.. Otherwise no...

You have been around since 2010, so have you run an OCLT? If you fail the OCLT, you will need to perform a SLAM.

Saying all your numbers are "correct" is not the same as posting your latest test results..

Thanks,

Jim R.

All my numbers are correct

From your shared PoolMath logs it looks like you added a whole lot of chlorine a couple days ago, but no testing since. You do know that if you wish to follow the SLAM Process, that is not a one and done thing.

What about iron in your water?

This was numbers two days ago. I have been keeping the chlorine in that range since then.

So I just did a chlorine test
24.5 FC
0.5 CC

The other test above was after I super chlorinated with SWG

Pale green color

Please follow the SLAM Process using the FC/CYA Levels
The FC level is far too high for your CYA. You are at risk of damaging your liner and are wasting chlorine.

I was trying to keep high to SLAM at 24 the last few days to see if it would help but its not

You report your CYA as 50. SLAM level FC is 20 ppm.
