Welcome to our forum.
Don't test the water twice a day and add chem's each time. There is an urge at first to try and get "perfect" water. You wind up filling the tub with chems and it is really hard to recover from it. In addition, the tub usually gets a lot of use when brand new, it is boiling funk off the users bodies and out of their pores. Combined with a lot of chem's it is a recipe for skanky water. Hence the 30 day first fill dump/refill recommendation. It is one of the common recommendations on the forum and has merit.
. However, each morning my chlorine levels are 0 (remember, not exact...test strip) but definetly no color on the strip and thus I have been adding chlorine every day. Tam
Don't micro-manage the water.Dump and refill after 30 days because you micro-managed the water.
Ah, I trained him well. I would add two things. The perfect value for any reading is a range, not an exact number. Also remember when you adjust the PH, it takes time for your chemicals to work. Wait 2 days to check again.
