I absolutely LOVE seeing great design and engineering put to good use with inexpensive materials. Bravo. The suspended pump is excellent. I assume both the suspension of the pump and its seperation...
I figured it was either flatout countertop mix or a similar concoction of white cement, silica fume, and plasticizer for super hard yet flexible cement.

Of all the marine creatures I've ever seen pictures or video of. This one to me captures my attention...
Nice. That's is a lot of work.
not exactLy clear. Are you doing a waterfall back into the tank and lighting the one side thru the glass?
I do a lot of exprimentation with screens and other aspects of my auquarium hobby including that aagonite pico screen. Since the fundamental screen material seems to have come up again ill try to...
Thank you for two great answers and the thread move.
I'm really looking to slim my project down. i've been trying to figure out how much distance from the glass the screen needs to grow. Anyone got an idea?
changing water adds new sea salt to the system which re-supplies trace elements. We do know that. im not sure what the stance is now days on manually adding these elements instead of changing water....
That's the root concept of some of my ideas. You can gain flow by just putting a little thought into the idea that you want to intentially direct the flow of water in and out of the device and direct...
I agree with the not being sold on the UAS *asis* as far as comparative effectiveness. The I just started with them..my jury is still out. That being said. There is no doubt is has advantages in...
Have a seat and put your reading glasses on...
I'm leaning on anyone that has details on the up flow bubble scrubber design. SantaMonica this would be the place to spew out all the bits of...
I've not yet had a need to. But castable plastic is a good option perhaps. Ive been waiting for the day encasing LEDs in clear plastic would be needed so I could do it. Ive used the product before....
After spending 2 days reading this entire mega thread. Im very happy to see the upflow design. I've made many waterfall scrubbers down to a pico 1g scrubber. Since I started making LED scrubbers I've...
I figured a microcontroller(Atmel/Arduino) would probably be pretty cheap and easy to set up the PWM timing required for it all. With an arduino, some quick digital write instructions should do it....
Well Its ..yet again been a VERY long time since I've visted you guys.I'm thrilled to see the V2 scrubber released.
In my travels as I venture further and further into electronics and micro...
A couple problems with that panel I see. By default even if things were equal from star mounted LED to the 1/2 watt round you would probably run into an intensity distance problem. I feel for it to...
I'm a fan of 1w LED usage. other than the extra wiring, its always made more sense to me. semi dependent on distance of course... I like the more even coverage. The spotlighting, not just visual but...
1/5th? Really!? That would be cool but it seems fairly low. It would be awesome however. Can anyone else confirm 1/5th red LED to t5ho? That would make LED very cost effective if that's all it really...
very interesting link ace. something that never entered my mind.
brian: CFLs and all other lights have a "spectrum" That is to say they put out light in a WIDE variety of NM(nanometer) ranges.
Into google..put "t5 spectrum"
It will show you the color(nm)...
While I am no expert on the matter. I can point out out Cheatomorpha and Green algae are not exactly the same thing. While I don't know much about the cellular structure of macro algae. From a "what...
Thanks SM. That provided at least a bit of info. Enough I think to warrent further investigation. But if anyone has any actual Dissolved oxygen readings from a fresh or salt tank thatvwould be very...
I'm involved in another project unrelated to general fish keeping. We use air stones to oxygenate the water. In Fresh water at about 77F Things seem to cap out at about 9 for Dissolved oxygen and...
Wall warts are not usually constant voltage or current limited devices. The LED kit he purchased already has the driver attached so he just needs a 12vdc power supply that can handle the current...
things will be just fine to run one set of 3. No worries.
1.5 amps would be enough for TWO 3wx3 lights.
If I recall right making a cheap LED driver isn't that hard. I think I made some Current limiting circuits awhile back that where adjustable current. With a cheap and easy to get LM317 IC a resistor...
Yes, you will still need another larger heatsink. You will probably need about .75 amps each one of those 3x3w LED arrays. So if you have two of those units one 12v 1.5amp supply will work. I've used...
It is very nice to have other people around that understand that. This is the reason that last LED DT lighting systen I did I used 1W LED's. It almost makes MORE sense to me. especially when you take...
I just got back from talking to the very very helpful folks at eshine about the 50w grow light. They pointed out to me and it had escaped my attention that 1w red LED's run lower voltage than regular...
Did you get that rapid LED kit you linked previously? That meanWell LPC-35-700 driver takes 120-240vac input. So you wouldn't need a 12vdc power supply. The kit shows it comes with a standard AC...
Correct me if someone finds better information. From what I can gather the epistar 1w LED are rated at (roughly) 35lm. one place said 35. one said 30 to 50. we can just call it 35 best bet.
Check...
IMO 1w LED are best. You'll have to back the 3W LEDs a ways away from the screen to get the right distribution and intensity
Another thing after looking at the eshinelight used.Due to the fact that the light is used at such close proximity to the target. The 5 Blue LED used in the array could easily be a waste of time...
The increase in penetration to the roots could also be partially attributed to the source point nature of the LED?
All light from the LED goes directly from the diode to the target with little to...
sorry for the extended absence. My conclusion here. At least as far as onesided screen goes. There was no noticeable benefit. If done double sided it would probably be inferior due to light...
I'm not sure. I wouldn't think that the method would be substantially better no matter what as we all know that a rough screen works fine. This method could possibly be easier to do. I more or less...
Day 15:
This is day 7 of having live stock in the tank(I got no growth until the day immediately after I added the fish). Up to that point there probably was not much for the algae to consume and...
Day 14:
Ammonia zero, nitrite zero, nitrate 5
