I use rodi water from the lfs. Don't have a test kit to test for tds.
Tds Meters are inexpensive. You can buy a hand held one or one that would install on the outlet of a ro,di system. Consider purchasing a unit of your own to ensure your starting with pure H2O. For around 100 to 150.00 you can purchase one to get the job done. Silica in the water is what my problem was years ago. The di part of the system removes it. I use synthetic salt with extra calcium,magnesium ect added in for corals and inverts. I have had failsafe results for years. Go to You tube and watch some of BRS (Bulk Reef Supply) videos on H2O quality it will help. Also more videos on substrate. I don't have any. I feel it traps Detritus and creates a ticking time bomb for a host of problems . Recently started using Kalkwasser. Results are very good . Keeping Calcium ,Alk.Magnesium,PH at stable levels in my mixed reef tank. Coralline algae grows on live rock like crazy with no diatoms . Sincerely hope this helps you. Happy Reefing.
