Drop checker works I used Hoppy's suggestion of adjusting distilled water to 4GkH and set it in my 75 with newly added pressurized CO2.
water is at 3kH and 5-6 gH
after a bit the indicator turned green and stayed there.
yesterday while doing main on the tank I shut off the CO2 so I could make adjustments on the bubble counter..I neglected to turn the CO2 back on..today the drop checker was blue..go figure..kind of embarrassing
but it looks like the drop checker works..LOL |
