Hi guys,
Recently my (arctic fox with Onzen) tub has gone from not requiring much attention to getting very dirty, very quickly and the filters have been dying faster - I use those foam batting ones - the first lasted about five months no problem, the last two have died after about a month. I've emptied, scrubbed, dried and refilled. Green scaling appeared on the filter plastic, and on the sides as a slight "tidemark."
I opened the spa door to inspect the Onzen dial and found everything was fine - except for some slight pooling of water on the floor of the inside of the tub on the right hand side. The water is slight, but brown and rusty looking. Should I be concerned?
Also, can someone list what their setup from clean, fresh water is, with regards to chemicals? Do people add anything? Everything?
