the algae that is stuck between my tennelus and hairgrass is getting for bad to worse ...

i suspect its due to low nitrates or low phosphates or too much light ...
can someone pls tell me which one issit so that i can deal accordingly?

can't really see from the picture. could it be hair or thread algea? If so, dose some KNO3 with the rest of the nutrients in healthy range should solve the problem.

you can also put in some platy. they like to eat hair/thread algea.

Cheers!

You might consider filling up the information chart so as to let folks do a better analysis of your tank conditions and why the algae is there.

Generally, when you have plant growth issues, go back to the routine and recheck everything in steps. Light -> CO2-> NO3->GH(Ca/Mg)->K->Traces->PO4. Make sure every of the nutrient is in non-limiting ranges by means of using very good test kits to test or dosing at max uptake rate coupled with weekly large water changes.

ok thanks for the help guys ... esp the flowchart of algae problems ...

time to invest in test kits then?
any cheap and good ones to recommend?

Something is very wrong if hair algae is growing on E.Tenellus. You CO2 content in the water is in question - my guess.

During the entire light period (2 watts per gallon!), do you have 20-35ppm of CO2 content in water?

This is important. Unless you are VERY sure about your CO2, then you move on to your N-P-K and follow by trace
