Yes, a full transplant from a mature 65g, this tank kept running through the transfer period.
Added 100% new saltwater and sand and brought to temp.
Day one, added 1/3 of the rock and corals and my gramma, my Anthais pair and my orchid dottyback.
Waited one week.
Day 8, added the second 1/3 rock and corals and my clown mated pair, my mandarin and my yellow tang.
Waited one week.
Day 16, the last 1/3 rock and coral and the bosses, my Blue Tang, Sailfin and Kole.
Done.
65g drained and packed away.
Some flashing, a couple of chases, here and there.
Alk, CA and MG remain stable and daily consumption did not change.
Nitrate and phosphate was low due to the 100% new water so I just dosed upwards back to the 10ppm nitrate and 0.08ppm phosphate level, it’s sat at this level with a 10% weekly change, this level seems easy to keep.
