View Full Version : crypt reproduction help

03-31-2010, 09:15 PM
so ive been keeping plant tanks for years, and my crypts do fine, but not reproduction, and after a few years they just dissapear.....what do you guys think?

i have a 90 gallon - 48x24x18w
4x54 t5 bulbs - three 10k and one 50/50 (came with it, neons look better)
use co2 with a ladder exchange system - co2 levels were really high last time i checked.
fertilize a good bit too.

i have a few small baby plants from the previously potted crypts - wendetii, etc......but no vigorous growth.

the jungle val is crazy i have to cut it back every 2 weeks or so..other plants seem to grow ok, but crypts just wont.....

thanks for your thoughts and help

The only things I would guess is not enough iron, or drastic pH changes?

A lot of the guys really into crypts these days are growing them emersed, as the availability of atmospheric CO2 makes them much easier to grow, and more likely to bloom:


though, of course, plenty of them are still grown in aquariums. :)

There's a subforum at APC (http://www.aquaticplantcentral.com/forumapc/cryptocorynes/) just for crypt lovers, and here's the blog of Ghazanfar Ghori (http://kryptokoryne.aquaticscape.com/), an enthusiast in the DC area, who comes highly recommended.
