Whats on my plants?

Hey guys could you please ID whats on my amazon swords leaves. It only appears to be on a few of them. Its almost like a red brown layer on top of the leaf (like velvet). How can I solve this?

Tank stats:
70l
2XT5 10000k lights (15 hours)
Daily Seachem Excel
Bi-weekly seachem flourish
Sera Florenette A root tabs

i can add more light if this will help, using CFL.

 

Looks like dead bba.....

 

@ivan I dont think its bba/ dead bba, as bba looks like little fibers etc. This is like a velvet layer its never raised. Unless this is another form of bba.

 

Is it possible to be diatoms?

 

I wouldnt add light. Not at al. If anything, Id cut your photo period almost in half to 8 hours max.

@Zoom ill try that out. I had this in my old tank over the past 2 years, on a few of the amazon leaves some are absolutely perfect green some get this... what ever it may be. I now have it in my new tank as i brought the amazon over and its also on the a. crispus and java fern. I took out the leaf and scratched hard and could not even make a mark on it. Could the plants not have a deficiency?

I have looked at many different types of algae and none seem to fit. Any ideas?

 

Definitely reduce your photoperiod. Set up your lights with a timer and allow a period of darkness around the middle ....siesta period....for 2-3 hours. Algae hate this dark period. Have around 10 hours of illumination per day + the 2-3 of darkness.

 

Thanks, Ill try that out, hope it works it doesnt bother me to much and I have had it for a long time I just want to get rid of it

 

oh man! let me know if you find a way to get rid of this. I have the exact same stuff growing?? appearing?? on my slower growing plants. I scrub it off and it just keeps coming back. my tank is low-tech and medium-light with a photo period of only 4-5 hours a day. the SAEs arent touching it

 

its BBA!!!! squirt it with excel

BBA will apear in different "strengths" but that is BBA no doubt... well imo anyway.

check KH fluctuation,ph and if you using gas make sure your ditribution/criculation is good.

 

ya reckon? even though it has no 'beard'? and it's reddish brown?

 

BBA does no need to have a beard..i can be in different "strengths" dependant on your tanks water parameteres..

BBA's other identifiyer is red brush algae so ya RED is it other colour.. do a google image search on red brush algae, you will see what i mean..

good luck..:top:

 

Tank update. The algae is gone my plants green and spotless.
What helped you may ask?@Anine, @Skyecloud im now running my tanks lights for 11 hours but they run for 6 hours ON, 3hours off, 5 hours on. This has worked like a bomb I havent changed anything but the lighting period and this worked great the plants look perfect. Thanks

 

What is the most effective on period followed by an off period?

If lights must be on for 10 hours a day does that mean it must be on 10 hours and then off for a few hours and then on again for 10 hours?

What is the total lights on time?

What is the total lights off period or how many short hour off times must you have

I want to get clarity on this please

 

i would say keep it on for 8 hours a day. know there is people wo keep it on for 4 hours and the of for 2 hours the on again for 4 hours

 

Ok let me clear things up.
During one day(24hours)
The total time my lights are on for is 11 hours.
They switch ON for 6 hours.
Then they switch off for 3 hours.
Then they switch on for 5 hours.
After these last 5 hours they switch off for the rest of the evening effectively 13 hours.
SO in summary they switch ON at 6:00 OFF at 11:00 ON at 14:00 OFF at 20:00 till the next morning when they switch on at 6:00 again the tank is spotless no algae what so ever

 

i have this bba aswell and im gonna try this on off thing. cant wait to see clean leaves!!

 

I would always have this on a few leaves. The tank is now absolutely spotless, the plants are really in the best condition I have ever seen them.
