Ok so I am busy getting my 800x800x600 cube set up and want to be self reliant on RO and saltwater. My question is what is the best salt to buy to mix my own salt water.
I have 2 x 260 litre JoJo water storage tanks 1 for RO which I am producing myself with a Waterboy unit the other one will be plumbed with a mixing pump for saltwater, as my cube will only be about 400 litres in total I will be doing 100 litre water changes every month, so how long can the saltwater that has been mixed stay in the tank?
Also what is the best specific gravity meter for salinity that a person can get and where?
