Hello there i have just set up a new 70l tank displaced to 60l and i am having a problem with a dark green/blue algae that is in small dots my tank has lots of ferns and moss in it and seems to be killing the leafs off any help would be appreciated
 
Blue green algae or bga is caused by low nitrate
I think that the ferts you are dosing are only micro you need to add npk either via ei method you can read up on this in the ferts section or with an all in one mix

too low of light .. get reflectors and set up another T8 tube ...
co2 - 30ppm ... (get dropchecker)
get NPK fertilizers! this is most important!
 
No, your lighting is fine. Adding more light will only increase the demand for NO3 (which is already problematic due to the BGA)

You might want to try a black-out for a few days. First remove as much BGA as possible, then block any lighting source using plastic bags, ... and after 4 days do a water change and dose nutritients.

*edit* You say you do not add NO3 or PO4?
 
A black out usually helps to cure the problem but be sure to buy some fertiliser which had Nitrates, Phosphates and Potassium in it, Tropica Plant Nutrition Plus is my recommendation. Your lighting seems fine to me.

I dose ferropol 24 and ferropol weekly
 
Ferropol 24 does not contain nitrates nor phosphates, only trace elements. Ferropol seems te be the same product but on weekly basis?

Adding trace elements (= micro elements) is a good start but your plants really need NO3, PO4 and carbon (= macro elements) to grow well.
 
Use the Ferropol as a source of trace elements. For KNO3 and KH2PO4 I recommend Easy-Life Fosfo and Nitro but that's my own preference. You can also buy dry salts instead of liquid fertilizers.

For dosing I recommend the Estimative Index. Check the EI sticky on this forum for more information.
 
Or for an all in one TPN+

+1 on TPN+ as recommended fert.
Or DIY TPN+ if you want to save money in the long run.
