I mixed rodi water with instant ocean-purple bag(its for reef and labeled as the best professional salt out there), and right now I need salt but can not wait a week for shipping nor I can pay their ridiculous double spiked up prices, I tested for both rodi water and the saltwater with salifert ammonia test kit and my ammonia reads 2.0!!! STOP using this salt or your fish and corals WILL die within an hour!!!, I know no one tests their new water especially for ammonia but I did for the sake of it(and all the salt I have right now is instant ocean purple brand for 400+ gallons), I tested the rodi water and read 0 ammonia 0 nitrites, etc. What am I supposed to do now tell me!, those acans wont survive even 30'
