Transitioning from hi-tech to lo-tech
I recently rescaped my tank with all low-tech plants -- swords, anubias, crypts, moss, bolbitis, lotus plants, etc.
A lot of these plants are ones I kept from a more hi-tech era in my aquarium.
But I'm looking for things to be a little more low maintenance and trying to reduce the overall moving parts I have in my system and the amount i spend on upkeep.
To this end, I am thinking of weaning the tank off of CO2. The tank is 125 gallons and has a decent amount of surface agitation between the sump, overflows and returns.
So my question -- will discontinuing CO2 cause massive melt of already established plants used to it? Should I gradually wean them off?
I already know I'll need to adjust all other things -- ferts, lights, etc. in response to slower growth -- and that the Ph will swing upwards a tad.
Anyone does this and can lend some experience or advice? Will this cause more or different algae challenges i should be aware of?
I can stay on CO2, but if it's not a requirement, I'd like to stop using it until I'm ready to go back to more demanding plants.
Any thoughts would be greatly appreciated.
