Re: Water and algae questions (was Re: [Killietalk] Golden Killies ID)
Wow, Excellent gentlemen,
I used to have much more coral sand (calcium carbonate) in my substrate.
Then a flurry of "You'll kill all your plants" came from aquatic plants list
and they recommended to get rid of the coral sand. I always liked the
extremely good root growth I got with it. now the plants are not near as
healthy. I did probe the sand about once a month to keep hydrates from
forming. When we lived in Florida I would snorkel in the clear pools of the
everglades, all those plants grew well in coral sand, the whole southern end
of FL is coral sand.
You guys would have loved to see those pools. mark
