Bro Cedric,
You mean you dose 250 ml of peroxide into your 100 litre tank?
You pour the whole 250 ml in at one go or let it drip over a period of time
THANKS
With more inform on LED these past 5 years I need to do some modification so that I can get full spectrum and time control to be added to have different light intensity and color over diffetent time of the day.
LED is a new technology.
If you believe in it you can consider.
Otherwise go for T5
For SPS tank go for high power LED like AI or Orphek.
Or if you know how to DIY, use good high power full spectrum LED
