20 gallon is easy, 10% water change 2 gallons, 20% 4 gallons. Buy distilled water and mix your ownYeah and one last thing, for water changes, if I were to use the saltwater from one fish store to fill up the tank would it be harmful to then use saltwater from another lfs during the water changes
the store i originally got the water from is about 2 hours away as there aren’t really any good lfs near me.
It’s definitely not the worst thing for me to get the water there and just try to get high amounts I was just wondering if there was an easier alternative
