Is SWCG shot?

[johngoose]

Long time lurker, first time poster. I'm on year 7 of this pool, and every year it seems like it's something new.
I'm stuck though, and I'm getting disillusioned with the pool company I usually get advice from.

Pool Size: 28000 << 18x36, side & bottom skimmer, 2 returns
Surface: Vinyl << needs to be replaced, but not the immediate problem
Chlorine: Salt Water Generator
SWG Type: Pentair iChlor 30 << Cleaned cells today. 8400 hours. Set at 100 right now.
Pump Pentair 1.0HP << Runs 24/7
Filter Pentair CC200. << Cleaned today
Heater Pentair Mastertemp 250 << set at 85)

Not sure if this is a symptom or the cause, but the iChlor has a flashing Green for Cell.

Readings yesterday

	Me	Pool Store
FC	0.0	0.0
pH	7.7	7.6
TA	130	125
CH	95	95
CYA	40	45
Salt	3600	3400
Phosphates (I read on here most people ignore, and this is the first time they measured it)		super high

I sprayed a bottle of PhosAway last night.
This morning added 12 gallons of 10% chlorine.

When I cleaned the blades on the SWCG this morning, there was a small amount of buildup. After I re-installed, everything lit up Green and was theoretically on, however 30 minutes later, Cell is flashing Green again.

I can tell I was fighting the early stages of an algae bloom and I'm hoping I caught it early enough.

Any advice is appreciated.

John,

A flashing cell light, when the cell is clean, means the cell is dead..

You got 7 years out of a cell that is way, way too small for your pool.. I am amazed...

I would recommend you replace the iChlor 30 with an IntelliChlor IC60.. (Some plumbing will be required, but the Power Center is the same.)

We always recommend a cell that is 2 x the volume of your pool. This is because cells are rated when running 24/7 at 100%

Thanks,

Jim R.

Thanks for the quick reply. Had a feeling that was going to be the answer. Amazon safe to buy?

Very good sources for replacement cells are Polytec Pools or Marina Pool Spa.
