Have a reefer xxl 750. 200 total volume Has been an established tank for a year before i bought my current home and have been running for 7 months.
Mixed reef 60/40 acro dominate
0.07 to .18 phosphates at all times
6 to 15 ppm nitrates
1350 mag
480 calcium
14.2 Alk
Reef crystals
I have always struggled with high Alk but all my corals still thrive at these levels. Making a salt change to red sea blue box and i did my first 20 gallon water change and have seen the alk drop to 13.3. My goal is to get down to 8 to 9 dkh slowly to allow the corals to acclimate to the change. My question is how so how soon can i do another 20 gallon water change all while trying not to strip my nutrients?
