With large tanks it's amazing how much fresh it actually takes to drop salinity. Lol I add 3-4 gallons every few days. Rises much easierThat's enough for me to wait 6 months before corals. I'll see if I can keep water parameters stable for a month as a "test".
Yes I'll keep an eye on that. I was wondering if the effect of salt creep would be significant over time.
I'm enjoying the large tank volume actually. Sprung a leak a few days ago, lost some water, topped up with RODI only (was curious to see salinity change) and no change to salinity! Great for newbs.
