    Awesome! Thank you!
  2. Fluval Spec II + Arduino Build Thread

    How about these? I've never used one or really looked into them, but they might work well as a dynamic fluid level sensor.
  3. Fluval Spec II + Arduino Build Thread

    The water changes I'll do manually (incase you are thinking that I am going to have them done automatically). I will have a button, though, that deactivates the ATO and circulation pump in order to make life a bit easier. Otherwise, for water changes, I just use saltwater that is of the same salinity as that that is already in the tank. I fill it up to when the top-off switch is lifted, which means it is at the original level. Hope that clears somethings up.
  4. Welcome! This is the build thread for my Arduino-controlled Fluval Spec II picoreef. I'll document my progress as I go with posts below and keep an overall up-to-date status on this header post (underneath the FTS). Any and all questions/comments are welcome. Thanks for looking! Running Hardware List - Fluval Spec II - stock pump - heater - Arduino Uno Lighting - 3 x CREE XT-E Royal Blue LEDs with 80 degree lenses - 3 x CREE XP-G2 Neutral White LEDs with 80 degree lenses Controller Features - controls lighting cycles - temperature regulation - leak detection - main screen as user interface - underneath-the-tank night lighting - ATO - easy water change button Filtration (from top to bottom) - floss - phosphate remover - activated carbon - rock rubble (Planned) Livestock - assorted zoanthids - a couple of mushrooms - a couple heads of frogspawn - (maybe) some SPS (like birdsnest) - (maybe) a small cleaner shrimp - CUC: ~ 3 blue-legged hermit crabs ~ 2 small snails FTS: Current Status Currently, I am planning the build and writing the first version of the code. Soon I hope to start collecting parts.

    Here is my math in trying to figure out the power supply requirements: So with all three blue LEDs, the voltage range is 8.55-10.5V. For the white LEDs is it 8.4-9.3V. Their current range is from 350-1500mA. The Mean Well LDD-700HW drivers each output at most 3 volts less than their input. Therefore, for the blue LED driver, it would need at least 13.5V. The white LED driver would need at least 12.3V. In total, that is 25.8V. Therefore, should I be looking for a power supply that changes 110V AC into about 30V DC at 2000mA? Would that power both of my drivers? Thanks in advance.

    Okay. I've done a bit of looking around, and I found the Mean Well LDD-700HW dimmable driver. Could I use one each of these to power the blues and whites? For the blues, I think I will use the CREE XT-E Royal Blue LEDs, and for white, Neutral White CREE XP-G2 LEDs. Do you guys think that these are good choices in terms of good for the corals, and in terms of visually nice for humans? Also, how do I figure out what power source I would need to power both of these? If I'm right, I could power both drivers from the same source, depending on the source, of course. But what numbers need to match? It would have to take 120V from the outlet and output what voltage for the drivers? Do the drivers automatically output the correct voltage from the LEDs?

    Could I use a buckpuck instead of a driver? If I want to go with 3 whites and 3 blues on separate lines could I use buckpucks instead? It seems like they are used more frequently for powering fewer LEDs than meanwell drivers. I'm not entirely sure what buckpucks are, so I may be way off base here.

    Okay thanks guys! I'll look into it and try to get a plan together and come back and ask you guys if I've done it properly. I won't be able to do it for a couple of days, so don't think I've just vanished. Give me about a week and I'll be back.

    How do I find the right power supply for multiple drivers?
  10. DIY LED Help

    So I could go with one of these for the blues and another for the whites? How do I figure out how to power them?
  11. DIY LED Help

    I like the Lumia chip, but I think it costs a bit too much for me. Also, I want the driver to be powered from a wall outlet as opposed to a battery or something. Could I possibly use a computer charger to power these like bob115 suggests? I also looked at your build really quickly. How did you power you LEDs? As for the mounting, I haven't gotten that far yet. I'm trying to get everything planned, first. And yeah, I've been programming for awhile now, so I can do that part. Its the electrics I have a problem with. I'm in college, but as a Bio/Chem major. I only tinker with electronics as a hobby in my spare time. Bob115, would I need separate drivers for each color LED? I don't want to do that to keep costs down and reduce the space this takes up. That's what's nice about the singly-addressable LEDs, they only take one pin on the arduino and are powered by the 5V+. That, with the pin for the blues, would mean I would have plenty of pins for everything else. (Also, I will probably control these with a ATtiny85 slave anyways.) Thanks for the help so far guys. I want to keep it simple but still give me the control over the intensity of each color. Keep the help comming!
  12. DIY LED Help

    Hello, I want to create a custom light fixture for my small, little Fluval Spec II. First, my plan for the tank is to hold zoas, mushrooms, and LPS, but I might want to try some low-maintaince SPS corals after some time so I want control over the light-intensity, with the maximum being able to maintain SPS. For the brain, I want to use an Arduino, which I am quite good at using so that is not the problem. My problem is that I do not have the knowledge of high power electronics, including LED systems used in the coral hobby. My plan right now is to use 3 or 4 CREE XT-E royal blue LEDs for the healthy blue light that the corals need and then 8 singly-addressable RGB LEDs for the color control (the color that we see so that the tank looks good). Do you guys think this is a good idea? Or should I use some CREE cool-white LEDs and maybe 3 RGB LEDs for color? Also, what dirver(s) should I use? I'm just not very good at this stuff. I want them to be powered by a wall outlet and dimable by an Arduino (pulse-width modulation). Basically I'm asking what are some good PWM controlled dimmable-drivers that could control a few CREE LEDs? Thank you for any help and suggestions.
  13. Hello everyone, I am currently in a 3D printing class at college where I need to create a novel product. I enjoy reefing and have had several tanks, so I want to incorporate this passion into my project. If you can think of something that would make a useful product for reef keepers could you let me know. If we end up using your idea or a derivative of it, I will personally send you one of the final products. It can be anything and complexity is not an issue since it is 3D additive manufacturing. Think outside of the box: heaters, fragging, fish or parasite traps, feeding, etc. Any help is appreciated. Thank you in advance!
  14. College Fluval Spec II

    Hello all! I doubt any of you remember but I had a college zoa garden a little while ago. It has been taken down for a couple of months, but I plan on bringing it back this year. This year, though, I will be a lot busier because I will be joining a lab so I plan to make it simpler and just more pleasing to the eye instead of many different rarer frags. My plan for my Fluval Spec II is to have three to four larger zoa, mushroom, or simple LPS frags where the rock they are on makes up most, if not all, of the rockscape. The kicker is I'll just stick with ordinary frags such as watermelons or radioactive dragon eyes, you know, cheaper and more common zoas that I can get bigger pieces of for cheaper. Then I was planning on getting the smallest cleaner shrimp I can get at the LFS (they usually have some really small ones). He will stay small for the 6-7 months he'll be in my little tank and then I can bring him home for my 29 gallon. Also, he'll be a little company and can crawl on my finger when I am lonely. To finish it all off, black sand! Boom! This will, I think, be a simple yet pretty looking tank. As for equipment, it will be the same set up as the zoa garden: Skkye IM LED for their 16 gallon tank JBJ ATO stock pump I'm just getting the thread started so go ahead and subscribe now, and when it is up and going, monthly FTS's will be posted below.
  15. Fluval Spec Zoa Garden Build Thread

    Final Update: The school year is over and the tank has come down. I forgot to take a final picture, but it didn't change much from the picture above. Everything is now in my 29 gallon at home. Overall, the tank was a success, but looking back here are a few changes I would retrospectively make: - no shrimp - black sand - more dynamic rockscape (I'm thinking it would have looked better with less rock, overall)
