Nothing Yet, but glad you`re here.

From a quick glance, I worry that your pump is too big for your filter. Hayward rates the filter at a maximum of 50gpm, but their own 1 hp above ground pumps don't get below that until you have 50' of head--long plumbing.
What brand and model of pump is it?

A 1 hp pump on an 8500 gal pool is certainly over-kill, even for an up-rated pump. I have a 1hp 2spd on my pool and it's far larger and STILL my 200# sand filter is barely within spec at full speed.

I suspect you need a smaller pump, or a smaller impeller on you pump, or a bigger filter.

You`re probably right. It was a package deal from the dealer.
It`s a Hayward Power Flow-LX, 1hp.@60gpm.---running into a Hayward C4001575XES cartridge filter, using the CX410RE-40 sq.ft. cartridge.
Dose spit the water back out the return with, how should I put it, GUSTO works.
Good news is the algae problem was nipped in it`s nasty little green buds and the pool is almost back to crystal clarity.
Two vacuumings, some brush work, and looks like one more vacuum job will make this an ugly memory.
Do you think I will blast the cartridge apart, figurative not literal, with this combination pump/filter?
Really don`t want to have to change(spend money on)anything this early on.
What do you suggest?
Thanks,
John

I'd like PoolDoc or one of the other pump experts to comment. They'll probably suggest putting in a smaller impeller to reduce the pump's GPM.

You could get a 3/4hp impeller and a new shaft seal for about $70.

Thanks for the come-back.
Not a bad price, but still not sure what the damage the pump flow as is will cause????
I just went and looked at what pulling the pump would rate on John`s grief-n-sweat scale and noticed...
The installers used silicone caulk on ALL the pump/filter fittings...a big thanks guys rolled between my ears-other things came out of my mouth.
If I choose to pull the pump, I`m really hoping they didn`t silicone the union between pump and filter and the hose connection.
Guess it will be the amount of potential damage leaving it would cause that will make the decision for me.

Take a look, are you sure it's silicone? A non-hardening thread seal would be appropriate and should come free with some encouragement. It you do replace the shaft seal, be careful with it - it's a no-lube / no fingerprints sort of thing.

Nope, no luck for me Big Dave.
It`s clear silicone caulking.
I don`t see anything on the union between pump and filter housing--so fingers crossed.
I wouldn`t pull the impeller, change the seal myself. I just don`t have the tools and equipment needed.
As I recall, even when I had the right pullers it was still a "touchy" little job.
I would pull the pump and take it somewhere that deals with pump motors if I really have to do it.
Thanks for the reply Big Dave.
