R. rotundifolia stunted but R. wallichii getting huge

**Jeffww** · 03-03-2013, 12:54 AM

R. wallichi getting to almost 2" wide now. Nice and orange. an inch at least a week.

R. rotundifolia. Pitiful, algae magnet stunting every day.

What could cause this anomoly? pH? The water is pretty acidic at around 6. The biggest culprit should be CO2 but it's only a 5g tank and the massive amount of CO2 I'm dumping in SHOULD be circulated. What's going on?

You definitely have some algae in there which is something rotala rotundifolia doesn't like. Mine had small shrunken leaves like that when I had an really bad thread algae outbreak. With that being said you should consider your lighting and fert schedule.

What kind of lighting are you using (the wattage and the brand/type), how far from the substrate is it, what is your fert regiment and what dare you doing for CO2?

Dosing full ei with 30w cfl on 5g 16" from the substrate. With co2. Im just confused why the more difficult plant does so well while the weed doesn't.

That "algae" is just diatoms...they will go away when it feels like it

I'm not complaining about the algae. I'm well aware how to deal with it.
