Experienced Planted fishtank keepers with DIYCo2, please help.
I have 20 gallon killifish tank , its planted , medium, lots of broad hair grass, some cambomba coralina , water wisteria and some dwarf grass and marimo balls and LOTS of riccia floating.
I dose it with seach excel for co2 source and Dry-fert dosing.
Now i have just started DIY CO2 (as liquid co2 bottle is finishing), I know plants don't need co2 at night so how to turn this off? The bubbles are not fast btw, just one giant bubble per 4/5 seconds but the ceramic dispenser keeps spurting minute bubbles constantly in the tank.
Will it hurt fish if kept on?
Will it hurt plants if kept on?
Should i keep pulling the Ceramic/glass co2 dispenser to the surface every-night to avoid co2 spike at night?
I have this sponge filter which throws bubbles at surface and creates a current (which also disperses the co2 bubbles around water as it reaches surface). Will this help remove excess co2?
