Hi everyone -
I periodically have metal staining in my liner pool. I am suffering with it right now (confirmed with a Vitamin C test). I checked the site and I am finding the copper and iron test on tftestkits.net. Are there any other metals I should be on the lookout for kits on and also, just confirming, they are only sold separately and not in a combo kit, etc? The Item numbers are K-1716 and K-1730.
I would like to get the kits to I can confirm the best approach for treatment but I dont yet know metal it is in the pool; does the Vitamin C test indicate one or the other typically?
Many thanks for your help!
