plants not growing
To Barry Cooper, Edd Kray, Bill Martin and anyone else who may be interested.
First, sorry about answering such old posts, but I haven't yet got caught up
with my e-mail after moving. I used to never have good luck with plants. If
they didn't die within a week the best I could do was to keep them green, but
they would not grow. Then about a year ago I was asking Karen Randall on
another list about the DIY CO2 reactor. During the conversation, someone else
asked about their snails' shells dissolving. Karen replied that a lot of
plants may pull iron and calcium out of the water quicker than the snails can
use it and suggested using supplements. She also stated that fluoride may be
deadly to snails.
This hit me like a bolt of lightning - I am a water plant operator and
the main thing that we remove from water is iron (because it stains clothes
and keeps soap from sudsing up) but plants NEED iron. We also add fluoride to
the water. Since I started adding iron to my tanks I grow plants very well
regardless of whether I add CO2 or not. Even with the poor lighting in most
small hoods, the plants still grow well with the iron additions.
Any LFS that has marine fish should have Kent Marine products and one
of their products is an iron supplement. Since I don't have a test kit for
iron, I use this at half strength with good results. If you can't find this
at a local shop, you could probably use regular garden iron (available at
home improvement shops and garden centers) at a VERY dilute solution (which
is probably what the Kent Marine stuff is anyway).
I feel that fish need iron too, so even the softer water killies
should not have a problem with trace amounts added at water change time, but
I would try it on the less expensive killies first just to be safe. My discus
seem to have no problems at all with this and enjoy the nice plant growth.
Hope you have better results with the plants in the future.
