This set comes with a "co2 reactor" and "tabs plus" apart from the other fertilizer stuffs. As stated on the instruction sheet, this unit needs to be placed just below the water surface.
Step 1: i placed the unit just below the surface of the water
Step 2: then i fixed in the rubber stopper
Step 3: i dropped 1 tablet into the given slot
Step 4: gas started generating and small bubbles started to disperse into the tank thru small holes below the reactor.
Step 5: Lasted only 30 seconds
Step 6: No bubbles left, everything is finished
I cannot re-try as i have already used 1 tablet/ will try again after 1 day.
Have i done sumtin wrong or is it this way it is done.
Please advise./ went for this as i was advised and read many sites that seachem excel is bad for vals and egeria... which i have in the tank...
Appreciate prompt response.
