Hydromatic Cartridge Replacement for The PRC 90

Very happy just like the one that came with original very satisfied I would buy again

Great product to keep pool clean

It works great, i put it in and within 24 hrs the water was clear

The Internal Diameter is not the same as the Blue Diamond Filters. The Filter did not fit properly and did not provide proper filtration and pressure in the tank. I tried both sides and multiple attempts to get it to seat properly. It's in the trash and I spent the extra $30 for one that works from Island Recreation.

Excellent product, was as advertised. Will buy again

Not right filter. The expenses to set back is very high. Did appreciate return cost being have of the product cost.

Works great with our pool.
