alright. Can I just use normal aquarium salt then just for this 2 gallons of water. I have plenty of the trace elements and such though in the water column because if you think about it I have 18 gallons worth of the trace elements and 2 gallons with none. Actually this sea salt is from france and is quite old haha and it says this salt does not supply iodide, a necessary nutrient. Still not suitable right?
Thanks.
