Blyxa issues


I've had this blyxa in my 20L for about 2 months. It started melting right away, and I read somewhere that it needs a healthy amount of iron in the water so I added more iron. That seemed to help alot, but in the last two weeks, it has curled up and started to look terrible. It's not melting, it just changed colors and started curling up. Any idea what would cause this? The other plants in the tank are doing well, no algae in site, save for a small amount of GDA on the glass.

20 gallon long
130w PC 10000K lighting @ 10 hrs/day
Pressurized CO2, 3bps
EI dosing
78* F
Flourite black/Flourite black sand
Flourish Root tabs

I would say you need to increase your CO2. You have alot of light for a pretty lengthy time and the higher the light, the more nutrient uptake and the more CO2 that is needed. My 2 cents.

Depending on your fish, I would also maybe lower the water temp down to around 74-75 degs

+1 or lower lighting

My Blyxa never really took off until I lowered my lighting to 7 hours. I was having a BBA issue, but the BBA never really affected the Blyxa, except that it never grew. Once I got my tank balanced it started growing like crazy.

Looks like your Blyxa is on it's way to recovery after the initial acclimatization via melting. Some of your leaves will die off but there will be new shoots coming. Your lighting as Dewalltheway was pointing out may be to much for your 20 gal. Shorten your lighting to a minimum 8 hrs with a rest period of 1-2 hours. That will also lower your temp pretty much. Good luck

You say you are dosing EI. What are your amounts that you are dosing and what other plants are in the tank?

1/4 tsp KNO3 & KH2PO4
1/8 tsp K2SO4
5 mL CSM+B solution (around 1ppm Iron)

Rotala indica and magenta, Cabomba (furcata?), Blyxa japonica, and Staurogyne sp.

Everything is growing like a weed except the Blyxa.

130w PC 10000K lighting on a 20 gallon long? That is a lot of lighting. I'd say you definitely need to either lower the light or increase co2 and nutrients accordingly. Here's a nutrient deficiency chart: http://www.finostrom.com.gr/images/a...lizers/map.htm

mikeb, what you have is an easy bake oven. you could probably cook brownies under that thing. if you do, send some my way.

i would cut your light in half. i have blyxa that does very well at 60 watts in a 20g long

Cut the lights in half, the blyxa still looks like crap though. Probably gonna get rid of it and try something else. Maybe I'll give blyxa another go, but I'm open to suggestions of something similar. Its only a 20 long, so I don't want anything too tall. Any ideas??
