What material is inside the starite system 3 model S7M120? Is it corrosion resistant also for salt water?

A  Answered on 4/27/2015 by InyoPools Product Specialist Patrick P.

Hi Helga, The internal and external tank for the Sta Rite System 3 S7M120 filter are constructed of glass-reinforced composite resin. This is a corrosion resistant tank ideal for salt water pools but not for ocean water as ocean water has a salt concentration which is 10 - 20 x's more than a standard salt pool.

I made a mistake on my original question, I actually need the information for the right part number for a STA-RITE Modular Media Filter - Model # S7M120. That would be for all filters to include, large and small cartridge and the air bleed filter. Also nee to know if you sell the o-ring clamps for the clamp assembly?

A  Answered on 5/29/2015 by InyoPools Product Specialist Patrick P.

Is this good for a 30,000 - 35,000 gallon pool?

A  Answered on 7/21/2015 by InyoPools Product Specialist Hector F.

Yes this filter has sufficient surface area for that sized pool. You just need to confirm that the gallons per minute rating with your model pump for your pool is compatible with that model filter.
