Steam plants goin Crazy


My steam plants (Ludwigia Red and baby Tears) are putting roots out like crazy.
I mean form each node, they about2-3 inches long.
They make the plants look like crap.
When I first got them from the LFS they did not have any roots.

My Ph = 6.8, KH=8, NO3= 10ppm PO=1-1.5ppm. temp 79.

It is because of some nutrient deficiency
The plants are growing fine. Also the Red Ludwiga is losing its red color.

what is your wpg for your lighting?

@ 38ppm co2, if you have high light you may not have enough NO3 and PO4 in there.

Im not good at spotting deficiencies, so hopefully someone else jumps in as well

Are you adding any trace elements? There are a few other trace elements like magneisum that might be a factor.

There are a few things that can cause yellowing. Just read the descriptions and pick which one best fits. Magnesium is just epsom salt if I remember right.

As long as the roots are clean white (healthy), I think they're okay.
What substrate do you have?

I can't stand water roots on my ludwigia and usually snap them off with tweezer when topping/replanting.

Same here Troy, but rimming every couple of day is getting boring..
plus maybe we may have some thing missing..

How long have you had them in your tank..
and what sort of Substrate you have

I noticed greater aerial root development on stems that were growing at an angle, or bent over slightly in strong filter current.

I hypothesised that the plant sends out these roots as a stabilising mechanism (when the roots reach the substrate, they will anchor the plant).

Very good observation Stu! The Ludwigia in my 10gal was planted across the back of the tank behind a piece of driftwood, and the dang things would never grow straight up. They always bent forward once they cleared the driftwood and entered the flow of the spray bar. Many times I'd trim the tops only to find the water roots had anchored into the driftwood.

kamla - The L. repens has occupied the tank since July '04. The substrate is Eco-Complete, lighting is 36W @ 10,000K (soon to be 6700K) with an optional/additional 2x13W @ 6700K, pressurized CO2, ferts, Rena XP1, yadda yadda.


Here's a picture from a month ago. The tank is nearly empty except for a dozen of the exceptional ludwigia tops that I wanted to keep for the replant.

Stu & Troy - you guys are on to something..
My L. repens are not growing straight. maybe thatís why they are trying to anchor themselves. but the baby tears have been in the tank for 3 months and have anchored themselves, but are still growing air roots..???

If you look on the right side of the picture I linked above, there's baby tears. No water roots from them, but they weren't in the current of the spraybar.

Last night I did the obvious thing and turned the spraybar around so it's hitting the back wall. There is enough turbulence along the back wall to keep oxygen at a safe level during the night, but the rest of the surface is very calm. CO2 levels seem much more stable and there is no current blowing the ludwigia around.
