Hello, Today I received my SPA, it's a CALSPA Classic (atlantic) 45 jets. " title="Very Happy" /> But I quickly realized that the merchant has made an error, my SPA has 75 ft ² Bio-Clean Anti-Bacterial Filter instead of 150 ft ² Bio-Clean Anti-Bacterial Filter as I had required. " title="Confused" /> They offer to refund me (250$) or replace the SPA, but I need to wait another 3-4 weeks if they replace the SPA! " title="Sad" /> Does double filtration change really something? Thank you Steve

75 sqft filtration is more than sufficient if kept clean - 150 is better, but an extra filter to have to clean and replace along the track - ask for much more of a refund because it'll cost them much more in hassle to replace with the correct model, plus the model you have would have been cheaper also

The technician explain me that the second filter is not running during the filtration cycle, but only when I activate the second motor manually... " title="Crying or Very sad" /> I will let down the double filtration system and keep me CALSPA like that.
