That's right, I posted what I felt to be the truth of the matter and that was apparently too much. I have been banned from the Algae Scrubber...
How many are you running them now? I think you were at 9 to 11, right? I'd leave it there for a week, see what the growth looks like, then add...
If you do the \ \ \ \ sort of idea and make is such that water flows <--- once algae builds up on the screen the water pressure will push through...
I agree that the bubbles are mostly BS. I'll have to let my L2 UAS grow out a bit and take video of what is going on. I have left the DIY bubble...
Will do over the weekend - had a busier than expected week
That almost looks like a fungus. Hard to tell from the pics, any chance you can take higher res ones?
After some experimentation and thought, I have just recently committed to a full production run of a slot pipe light blocker. It's been a long...
I would say that I used to advocate no water changes, but only for purposes of nutrient reduction. The argument still can be made either way on...
Making one of the DRs half power is not going to affect much though. Still a lot of output. In fact my new version has the ability to jumper all...
Haven't tried it myself but I recall someone else did and they didn't turn on at 1/3 of 700mA. Maybe wire one of the reds with one blue and the CW...
What's funny ace is that I do include a filter sock with my units now. But it is mainly to act as a bubble trap, just below the surface so that...
Correct
Is this the passage you are referring to? I was expecting to see a direct slam...this one is kind of indirect. One could make the argument that...
Take the diffuser off. If you have a base of growth you don't need it. Plus, 80 grit on acrylic is cutting down your light tremendously....
For Arduino questions, you would be best to ask those on the Arduino forum, which is huge and extremely helpful, for anyone that needs help - very...
Power (watts) = Current (amps) x Voltage (volts). This is usually represented by the equation P=IV. The driver is rated for a maximum 48V drop...
Hmmm... Not sure what would be causing that. Your Vf is fine, 35V total drop @ 700mA = 24.5W, so you're well under the 33.6W maximum. The...
Test the voltage drop first
You need to get the pad hot enough, quick enough to accept the solder as a hot joint. Soldering on the heat sink can easily result in a cold...
By pre-tinning the LEDs after they are mounted on the heat sink, you are actually doing the exact opposite. The heat sink draws the heat away...
