Thanks a million Randy, Yes using your 2 part DIY Soda ASh BRS. OK will proceed with same dosing and watch pH and alk !!!!If you are using one of my DIY recipes for the hydroxide and were using one of my DIY recipes for the soda ash part (as BRS sells), then the volume dosed starts the same and may need to be tweaked if the demand for alk rises due to the higher pH.
