Stems near heater keep melting - help

As the title states - in the back corner of my 6g tank where my heater is (25W Archeae Ultra Slim), I am having trouble keeping stems happy. I have tried a couple of types - most recently Limnophila palustris, and before that Rotala sp. Magenta. While not all of the leaves die, the stems get super soft and brown and then break away. I am guessing it is due to the localized warmer water (although there is very good water flow in that corner) - as there is nothing different there in terms of soil/root tabs then in the rest of the tank.

Does this make sense? If so, does anyone have a good recommendation for a plant that would do well in the slightly warmer water (the heater is only set for 74 - but I am guessing the local temps are higher)?

It does - it goes from the front left corner of the tank and travels counterclockwise to the front right, back right (heater), then where I am having problems with the stems. Unfortunately I can't reverse the flow - as it would disrupt all of the stems on the back of the tank (and it is a small tank). And the way the tank is setup - moving the filter to the opposite side of the tank also won't work.

Yeah - not really. Where I have it is one of the few places I could "hide" it - although since the plants aren't making it, hiding it really isn't working...

Bury the heater, preferably in the middle of the tank. If its small, the heater shouldn't have a problem keeping the whole tank warm.

Is there light over in that corner?

Plenty of light in the corner - so I don't think that is the problem. Before I go disrupting the tank too much, I will see if I can find another way before burying the heater (although it would have been nice if I did that to start)

ive encountered the same and found only one solution, which was to install the heater vertically rather than horizontally. seems to keep my plants much happier though its likeliy less efficient...

Thanks Julie - but this tank is too small for the Hydor. I have one on my 10g and love it - but this is a 6g with a Finnex PX-360 set right next to the tank. So no room in between for an inline. Thanks though.

This is an interesting post. I don't have the answer to your question (sorry Oz) but I think you may have solved a similar mystery going on in one of my tanks....

I have two c.helferi bunches growing in a tank, one of which is right in front of my heater (attempts to hide the heater) and it never grows nearly as high as the other bunch growing on the other side of the tank. The leaves of the plant in front of the heater always turns brown before reaching the surface of the water. While the other bunch growing elsewhere in the tank has long glorious leaves that flow over the water surface. You're post here is making me wonder whether this is the same problem as yours.

Pearling.....it's way overrated.

I am not sure how strong the relationship between the location of the heater and the melting stems is - as I have gotten a couple of opinions that there likely isn't an association between the two. But, it just seems funny that the stems there melt - but the same stem in a different place is OK.

Going to try a few more times, and if no success - maybe try burying the heater.

And Julie - if you still have that heater next time there is a meet - I will take it from you and put it in storage - as would like to do another tank later this year sometime.
