I am looking forward to seeing those new pics. I am really happy that your tank has hit a very stable place. Its freeing when our tanks settle into that stable place so that we can just enjoy them without so much anxiety.Things have been going well. Will post new pics ASAP.
Current Water parameters tested in tank= 78 degrees, Salinity-=1.025, Alk= 6.7 DKH, Ca = 460, PH= 8.0 . I backed off of water changes and have been doing Kalkwasser in my ATO for the last 9 months now - have been very stable this way with the parameters listed above. DKH is lower now due to needing a water change - has been running 7.2 -7.8.
Tested the new water= Fritz RPO - mixed to 78 degrees and 1.025. Alk- 9.7DKH, PH= 8.2, Ca = 460
So, I think doing a 20 gallon water change with parameters above new water to my 190 total gallons in system wouold be enough of a ALK change to cause stess? Opinions?
I would not expect 20 gallons of a water change to drastically change your alk since it is only about 10%. I am not very experienced with sps however but 10% WCs have no impact on my lps/softie coral. Are you going to periodically continue with 20 gallon WCs until your total alk is slowly raised?
I see the club has a frag swap coming up in April. I will try to make that.
