New owner installing this week

I think around 7600-7800 gallons. Don't have it in front of me. Pool guy threw in the upgraded filter for free and it comes with the bigger pump

If you can, you're going to want to exchange that pump for something smaller. 1.5hp is overkill for your pool. We see this all the time particularly on AG pools. Pump/filter combos are sold that are badly mismatched. Pool stores tell customers, "Oh, we'll upgrade to this great big pump for you." Customers don't know any better and think, hey, what a nice guy! But, in reality, it is not good. You don't want a big pump. You want a smaller pump paired with a larger filter. I'm not that familiar with cartridge filter sizes so I'll let someone else advise you more about this combo but I do know that you really don't want that big pump. The power of a too big pump can destroy cartridges or if it is a sand filter, can force debris right through the sand bed without filter.

If it is at all possible, don't install your pump and filter yet and see if you can exchange it for something else. Honestly, I'd go with a sand filter if you have the option rather than the cartridge. Much easier to use and maintain for most people. (I will tell you that all the mods on this forum and I think many of the support team people have sand filters.)

Let me see if I can find one of pump/filter people to chime in here and offer you a better combination in the hopes that it is not too late for you to make a change. I hope it isn't too late. You're going to be sorry you have that big pump, I'm afraid.

Appreciate the info. I agree pump was too big. I gotta be honest he did say upgraded filter so maybe he is pairing it with the smaller pump. I don't have it in my possession yet I had read and heard that cartridge filters systems were pretty easy and actually filtered better than sand but not as good as DE as long as you rinse filter and replace when needed I am really going by what the pool guy was recommending. He installed a few friends pool and they recommended him highly. I haven't maintained a pool since I was a teenager ( many years ago) and it was a sand filter.

Get the smaller the pump if you can but I wouldn't be too concerned because a 1.5 HP AG pump is not usually that powerful anyway and not that over powered for a 150 sq-ft filter. I think the Xtreme comes with a Matrix and a 1.5 HP has a flow rate of around 53 GPM which puts the flow rate right below the APSP recommendations of 0.375 GPM/sq-ft so it should be ok.
