brown edges of frogbit
I put a few things of frogbit in my tank 2 weeks ago. I've read on
this message board that it is a good way to monitor iron levels. They have looked healthy - but recently the edges or tips of the leaves have begun to turn brown. Do you think this indicates low iron? TIA, cindy |

I thought they get yellow from low iron? Mine go brown because of aphids,
or if they are right underneath my eheim fertilizer doser. "cindy" wrote in message m... I put a few things of frogbit in my tank 2 weeks ago.

I am not sure, but I think the leaves turning brown and looking like
they are dying is more a sign of nitrate defiency than iron. Iron defiency looks like yellow where there should be green, not brown where there should be green. |

brown edges of frogbit
How big are aphids? I have little bugs, about the size of a small
grain of sand. They rest on top of the frogbit and are dark black in color. Are those them? I always left them there, as I figured they were a good source of free food for baby fish - I assume baby fish are eating them, because I keep having new baby cherry barbs everytime I look at the tank. If I disturb the bugs by blowing on them or just opening the top they bounce around on the top of the water. I don't know what else I can say to describe them. Are aphids or the animals I describe harmful in any way? The leaves of my frogbit are almost never brown, usually only one leaf or two is brown, but it isn't enough to worry me. I stopped supplementing for about 2 weeks and the frogbit leaves started to turn brown, so I assumed it was just the nitrate and not anything else. They were, however, putting out small new leaves, not as large as normal leaves, but there was new growth. I did occasionly dose potassium, but never dosed nitrate. Reason I stopped dosing so much is that I ran out of CO2 and haven't gotten it filled yet - plants are still fine, just a little extra algae is all. |
