My Red Sea drop check arrived today. I have indicator solution that came with the drop check but the contents are not identified it just says that it is flammable. I also have wide range PH test solution but its' contents are not labeled either. Are either of these Bromo? How can I get Bromothymol blue and know that is what I have?
I have also been thinking alot about my CO2 system and why I would not have enough in the water. I know it is a common practice when filling tanks of particular gas/liquid to top off with what is know as a nitrogen head. I wonder if all this time I've been dosing only highly dilluted CO2 from the top of my cylinder. I have a 200lb cylinder so I suspect that if it was topped with nitrogen it would take a significant amount of time for it to vent. I also noticed when looking things over that the CO2 is industrial grade but I don't know if that matters much. Any thoughts on this?
