Budblue's floating surface scrubber

[SantaMonica]

It looks to me like it is getting no light at all. Since it is not a SURF2, and I did not build the light, I have no idea what is really inside it.

Try using a 23 watt CFL 2700k floodlight instead.

Then it's just has low power leds, not 3w leds. What does the power supply say?

[budblue]

hi sm
when I said it didn't I meant hot
it does get warm but not hot
The power supply is 700mA



3-21vdc with the leds taking 2.5V each (I have measured this with meter)



Power = amps x volts - 700 x 2.5 = 1.75W



1.75 x 4(led) = 7W total



Power supply is good for 9W max

Buy some enteromorpha sp. and throw it in if you can find it many screens end up growing this algae anyways.

Ulva sp. may even change shape to bind to the grabber material

What do the nutrients measure
