Wa dalam process nak DIY. Total LEDs - 65 white, 64 Royal blue, 22 drivers. Total LED wattage - 516Watts. Exisiting lights 2x250wMH + 6x39W T5 = 734W (belom masok losses)
Wa kira2, ROI dalam 2.5years (including bulbs replacement).
Are you using tap water to do your water change? Tap water contain lots of stuffs including nitrates.
Best if you use distilled or DI or DI/RO water, so that you will not put the impurities back into your tank.
This "C" shape looks very strange. Play around and you will get a hang of it. Try to get those big ones. Your existing ones are too small and when you stack up like that, will topple. May be you see those members already setup and post in SRC and get some ideas from there.
