i refilled the spa about a month ago and used eco spray filter cleaner. i rinsed well and filled the spa and it had a light green tint to it and i had some foam right off the bat. now i had waxed the spa and cleaned everything so i had no idea what it was making the green tint color and foam. but i just soaked my 5 filters in eco soak over night and i rinsed them and installed them. water turned a milky blue with some foam with the jets on. it takes about 20 seconds just to barely see the bottom of the spa. about a minute later it is clear but has a light blue tint now.
eco spray is green and eco soak is blue.
eco soak does say to let the filters air dry witch i didn't do. i had rinsed them really well and rinse them again before i installed each one.
i used 3 cups of spa soak in 15 gallons of water for 5 filters. i wouldn't think there was much residue left on the filters but it did turn the water from a green tint to a blue tint. it doesn't seem like the stuff breaks down in water since i still had the foam and green tint from the eco spray a month after use.
so i'm debating if i should drain and refill or just use the spa for another two months?
