    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?

    I'm using the AM salt from Idol. ~690 a 20kg box. Its all about personal choice

    Get a Refractometer with Automatic Temperature Compensation to test SG, should set you back about 1k

    The best salinity meter is the tropic marine pro hydrometer. Even refractometers need to be calibrated using one of these. They cost about R570 from Idol Marine.
