Hi all.... first post...
I've recently re-entered aquarium keeping, and have set up a 165L planted tank. Through my 5yo son.....
Lights - Grobeam LEDs x2 - approx 50-60 PAR - 8hr duration
CO2 injected
pH controller
(While I investigate EI dosing I'm using Flourish comp/N/P/K/Fe)
water KH 3.6 deg
I put Sera's drop checker in the tank when setting up, and set the pH controller to 7.00. CO2 runs 24hr. The pH has remained stable - but the drop checker colour has been lightening, yellowing gradually over the past 48hr, tonight was a real light yellow-green, the colour Sera suggests CO2 is too high.
From a KH/CO2 chart, my level should only be around 10ppm, and fairly stable - I don't understand why the drop checker seems to be showing progressive change? Are there other factors in play?
I only really had the drop checker in as a cross-check while the pH controller was running in, doesn't really seem useful now, but results are incongruous....
