Behaviour you ask? Yes! I have a 125g planted tank, at the moment
stocked with about 27 Vals (max 5") and 42 Anacharis (max 17").

Here's what I've been observing... my Anacharis go through a cycle
(haven't yet determined the period) wherein they grow perfectly
straight, and then bend their tops to form a candy-cane shape. It is
INDEPENDENT of the light cycle. I've even left them on for 36h and the
effect is the same. (?) It doesn't seem to concide with some timeframe
after their feeding either.



I fertilize with chelated-iron, Fourish Excel (1/3 dosage only),
potassium permanganate (yes!), and I've also got 2 "Plant-GRO sticks
buried in the plant patches. Their analysis is 16-9-12

I also inject CO2 generously using the Carbo-plus electrolysis unit.
They can grow almost an inch a day.

Any ideas? Anyone else observe this with Anacharis, or any plant for
that matter?

Now looking back at this message again. This is such a coincidence. I
just realised you're the poster who solved my "Anacharis Melt" problem.
The same issue must apply to you. You're dosing with Excel. That could
be causing the Anacharis to curve?
