I would be interested to know the cost of phosphate remover if someone would not mind posting the info, helpful to know the dosing level too.
Cost of phosphate remover

I've used natural chemistry products in the past, the phosphate remover isn't too expensive maybe around 25 dollars (phosfree 3L) but the weekly maintenance product Pool Perfect + Phos free is a little pricey; that product is a mix of the phosphate remover and an enzyme to break down oils etc. Although as it's been said on here many times before, if you keep an eye on your chlorine level you really shouldn't need to worry about phosphates.
A quick search of online sites, Leslies has PhosFree 2 L for $32, 2 L Pool Perfect for $42. Mailorder sources were $18 and $23 respectively.
Another search of dosage says " "20,000 gal pool with 300 ppb phosphates need initial dose of 1 Liter."
dosage of Pool Perfect for same pool would be 0.1 Liter per week.
So, for that pool as described, $16 initially, plus $4.20 per week, per Leslie's pricing
$234/yr if you add the stuff all year.

Very roughly speaking, the initial dose to reduce higher phosphate levels can be quite expensive. My pool with 2000-3000 ppb would require more than $100 worth of product. Maintenance doses are more comparable to weekly PolyQuat 60 costs, but technically speaking the amount of maintenance dosing really depends on the rate of introduction of new phosphate into the pool and this obviously depends a lot on fill water and evaporation as well as on blown-in fertilized soil.
And, of course, it depends on whether the phosphates are all orthophosphate which is the only form that phosphate removers remove. If there are other small organic phosphates in the water, then the algae can still use those (more slowly) to grow. Use of the product can temporarily cloud the water. This is why this isn't generally recommended on this forum. If it's used at all, it needs to be looked at in the same vein as other algaecide products that aren't perfectly effective. Also, as noted, one can have high phosphates and nitrates in a pool and still keep it algae free through maintaining the proper Free Chlorine (FC) level relative to the Cyanuric Acid (CYA) level as per the Chlorine / CYA Chart.

For ranges in the thousands, there is a product called phos floc which drops the levels to around 600 then phos free can be used. After using phos floc it looked like a white fluffy cloud on the bottom of the pool but it did work as instructed. phos floc is 25 dollars per 4lbs which treats 10,000 gal. So the average size pool would be spending at least $75 if their phosphates are in the 1000s
