I'm about to switch my salt from Instant Ocean to Tropic Marin Pro.
I do 5 gallon water changes weekly on my 40 gallon cube. My IO salinity is at 1.025 and I plan to match it with TMP. Not dosing anything right now.
Would 5 gallons put any shock to the tank or should I start off with a smaller amount for my first TMP WC?
