I am having issues with LOW alkalinity. 4-5 dkh. I just realized that I was having these problems when I noticed my corals stopped growing. I plan to dose with Red Sea KH/ALK Foundation B to raise my alk slowly. I am going to do a large water change 75% on my 29 gallon and replenish with red sea coral pro salt first and then I will test again before dosing. When I start dosing the foundation B will CoralLife Liquid Calcium help keep my calcium numbers in check? My nitrate is 50 or over and that needs to go down as well so I hope the water change will help. My PH is reading between 8.2-8.4.
