G'day CP world
My experience says NEVER grow any plant including CPs in still water.
For an aquarium with a lid, keeping 100% humidity will mean that "excess"
water is irrelevant, but there again Sarracenia Pinguicula, Utricularia and
Dionaea all grow best with a constant flow of water over their roots. If
you cannot arrange that, placing some hollow medium under pots to allow
excess water to drain away is fine.
Just to re-iterate, if you are using an aquarium, you shouldn't have to
water at all!

I grow U biloba in a tropical aquarium with circulation going. Also works
on Aldrovanda, but I do not grow Av now - too boring. --------Question -
has anyone flowered Av?

Most pesticides contain, besides the poison, detergents and suspenders (ie
talc if solid, or solvents). Don't blame the Daconil fungicide for the poor
health of your plants - it is the detergents fault. All helophytes and
aquaphytes are very sensitive to disturbance in membranes, and of course any
detergent will wreck root or leaf membranes.
All fungi need a lot of nitrogen to grow, so if you have fungi, change your
medium and/or water!
