Solcielo lawrencia;117050 said:If the only issue with drop checkers is the extreme amount of time lag (hours) before it tells us the CO2 concentration, then there are ways to improve upon it so that it's immediate, less than one minute. All that is required is to agitate the solution so that the gas diffuses much faster.
Solcielo lawrencia;117075 said:A small stainless steel ball bearing (one you can get from skateboard bearings) can be placed inside the drop checker if the opening is large enough. Moving a magnet outside the tank next to the drop checker will cause the bearing to move thus creating agitation of the solution. The only downside is that it is manual. Something automatic requires something more complicated.
Asmack Arabia;117078 said:i was thinking of doing the testing outside the tank. like you put an X amount of tank water in a cylinder then add X drops of the solution, shake, then you get an instant result.
is there such a thing ?
BriDroid;117080 said:That is a nice idea. I'll have to see if I can find a small enough bearing.
Would the indicator solution or the KH solution cause the bearing to rust, meaning I would have to change the drop checker solution out more often?

Tom Barr;116051 said:pH drop is relative to an ambient non CO2 enriched tank, which should be about 2-3 ppm if things are going well.
If you view the pH/Kh/CO2 chart, for any KH value.the pH drop of 1.0- to 1.3 or thereabouts will = about 30-45 ppm.
That is independent of KH.
If the KH changes, or other acids are added to the system, the pH before/after start point will change, but the influence of pH due solely to CO2 will not.
Slow progressive adjustments and observations often are the best solution for CO2. Start with the pH/KH table, then adjust from there using the pH drop.
