That is the normal method of vegetative reproduction in
Cryptocorynes. Congratulations on your babies!<g>

Depending on your light levels, you will have more trouble with
algae with higher amounts of nitrate. With low - moderate light
levels, some people find that algae is controllable with nitrate
levels up to about 20 ppm. For those of us who use stronger light
levels, 5-10 ppm seems to be the higest you can go without
problems. Personally, I find that I seldom have any measurable
nitrate level in my tanks.
While I've seen the advice that 40-60 ppm nitrate are acceptable
for fresh water fish, this doesn't take into consideration that
nitrate acts as a marker for other substances building in the
water that we cannot easily measure. I would not feel comfortable
with levels this high even in a fish-only system, and particularly
with Discus, which are particularly susceptible to problems when
not kept in very clean water.
