Had a minor emergency when I got home from work. The chamber that my heater and pump are in had almost no water and fizzy bubbles were the only thing coming out of the nozzle. I quick turned off pump and thought I’d see if it needed cleaning, decided to do a water change and vacuum that chamber. 2nd disaster - I must have grabbed RODI instead of saltwater to refill a couple gallons in my tank and threw the salt balance off. Fixed now and my Rasta Zoa is throwing a little love my way
