Has this ever happened to you where you just completely forget? Like doing tests or acclimating? I feel so embarrassed...
My tank is a 20g and my question is when doing a water change, Let's say I take 3-4 inches of water out, How much salt do I add when putting new RO water in? It says add 1kg of salt per 25 litres of water. How much do I add if I want to take 3-4 inches out and add salt?
I'm horrible at maths.
I just completely forgot and I'm just so confused...
