Why do you want to know GH?Hi, does anyone know what the GH of instant ocean is after being added to reverse osmosis water at full salinity aka 1.026 so I can try and figure out what my aquarium water GH is.
thanks
David.
The fish I have currently are brackish as juveniles then move up to full saltwater as adults loads of places mention their GH requirements so I want to figure out the GH of the water after adding IO as there’s no GH test kits for saltwater I figured if someone knew the standard IO GH I could calculate it that way. Also as I’m using a lower salinity of instant ocean with reverse osmosis water I’m wondering if there’s enough GH or any risk of osmotic shock.
