Wow. Henry you were right. The limiting factor in my tank were the macros. I now see heavy pearling in my tank even days after the water change, which I never got before. The plants have become greener and the algae infestation has reduced drastically(removed the remaining algae infested leaves too). I am now adding macros + trace elements and doing 60% water change weekly. That was some really useful advice. I dropped the idea of upgrading to T5HO. I feel my current LED floodlight + PL lights look OK for my tank.
