I would think that you have too much lighting, but I'll let an expert advise you!!

Hi ZAID,

how are you ? welcome to the forum.
your two algae are CO2 Light and flow related mate.

CO2 must be on before lights ON that is very important. Because plants start their process as soon as the light is on. The first hours of the photoperiod is very important, so it is during these first hours that CO2 need to be at optimum. Try to turn it on at least 1 hour before light on to achieve a better concentration before light on. I suggest you to do that on a sunday when you are at home for a full day to have an eye on your fish, to be sure that this change want harm them.

An other advice would be to reduce a bit your light instead of increasing your CO2, because your CO2 is not at a good level for the amount of light you have. I don't how is your set up, but to do that you can raise your light a bit from the water surface, or if you have a controller on your LED unit just reduce intensity. An other way would be to place a sheet of something between water and light that would reduce intensity. Some thing that can help also during your algae invasion is turning off light at 8 PM instead of 9 PM, or even before. If you turn off light at 8 pm no need to change the time of CO2 off, but if you turn it off a 7 pm than change you CO2 off at 5 PM, it will help your fish.

Your filter seem to be good and enough for the size of the tank, but maybe outlet filter is not well place. try to play with outlet position to see if flow can be improve. Flow is very very important for CO2 and nutrient distribution.
95% of algae is due to C02,FLOW and LIGHT management that is not adequate.

Note that all changes will not make an direct effect you need at least 2 or 3 weeks to see a start of change.
I am not an expert at all on this forum, but I think that these advices are good. It would be great also if some one that have large fish like your (discus or angel) could give you advices. I have never have big fish in a CO2 enriched tank. All CO2 changes must be done when you are there and by having an eye on your fish behavior.

Hope this will help.
Have a good battle

cheers
Zanguli
