I purchased a used tank and havnt had one before. My question is I completly emptied it out and want to refill it now. How much salt do I add to the water? its an 80g.
depends on the brand of salt you choose to use. each package will have its own guidlines set up hit a certain SG but a refractometer is what is really need to measure as you go to make sure you have enough or hit your target range.
