Too many swords?

[AaronW]

I have a tank with about 8 or 9 swords in a 4 foot tank. It's a low light setup. I use DIY oscomote root tabs and I dose API leaf zone and seachem potassium. The substrate is flourite sand mix.

They don't seem to be doing so well. Is it possible there's too many in the tank competing for nutrients??

Maybe they need a carbon source. If not co2 then at least excel or glut.

How big is the tank and what light are you using?

It's a I keep messing it up. Thought it was a 60 gal. But I measured it and it's a 50 gal. The light I'm using is single fluorescent fixture with something very low like a 3700k rating. But the swords seemed to like the lower light instead of the T-5 28w.

Substrate is a flourite sand mixture. Perhaps I need to upgrade my lighting. Too me it looks like a nutrient deficiency though

Agreed I found a bottle of Co2 booster. Will start dosing daily
