    Some of my green coral (GSP, Green slimer, green zoas) are starting to lose color but everything else is doing great. I think I have too much UV (as much as cool white or RB) and will be swapping a few for normal blue this week!

    Besides that great growth. My green slimmer has a "kink" in it from fast growth towards the new light, and a lot of the polyps bases are "stretched" I'll take a few pics tonight.

    Par is only 300 (about 50-100 below my MH) PO4 and nutrients are all at zero, Alk (10.6) calc (474) mg (1300)

    Still trying to get the light "just right" birdnests are bleaching, acro is loving it and green slimer is browning! [​IMG]

    I built an arduino shield to replace my breadboard. Just need to crimp ethernet plugs onto my driver wires.

    Had a 3 week honeymoon in the mix, but my light controller is done and I am very happy with it! 8 PWM channels! Time to build some cabinet wall/doors and mount inside.

    4 month update!

    [​IMG]

    I have most of the corals I want (minus a few choice SPS pieces) but don't plan on adding anything until I can establish the growth I want.

    The canopy frame has panels that snap on with magnets, makes tank maintenance a breeze! I used pocket screws to assemble the panels but the routing on the panels is too delicate and after 2 months of humidity they have started to crack.

    I have learned a lot of things going pure DIY.

    LED DIY - I have spent way more than I would have going with a good retail option. Between replacing a strand of LEDs that I burnt out and 3 Meanwell drivers that failed due to humidity I have tons of regrets. I'll keep this DIY setup will go to a future frag tank and my display will use something nice. I am switching to a DC-DC system instead of buying more meanwells (I used up my 2 spares)

    Some LED DIY tips. - I like the color blending by not using lenses but I noticed a lot of PAR inconsistencies, it really drops out along the edges and depth. I am rebuilding my canopy to drop the fixtures down 4" and am adding lenses to the big channels (royal blue and cool whites) the warm colors will stay without lenses and I feel they play a big role in getting good color pop from fish and corals.

    Lime versus green - I bought some lime LEDs to replace greens on one of my warm channels, I will report back.

    WP-40 - Going with 1 big pump instead of 2 smaller ones was a mistake. In an open tank with artificial looking structures it might work, but not with my bulk rock work. I added a korlia to help cover some dead spots, but I dislike how the sand bed is pushed around by huge flow required from a single point. The Jeboa WP40 works if clean, but loses 50-70% of it's flow if dirty, the drive shaft does not operate smoothly with the smallest amount of film.

    Fuge - I run my fuge from 3:00 am-6:00 pm (kicks on 6 hours before lights go on and stays on while lights are high). I did a lot of testing and found that 15 hours of high intensity red/blue LEDs grows the most algae in my system. I pull out 2 handfuls of cheato every 5 days. I have also noticed the best "glass dusting" results by running the fuge 6 hours before the lights turn on, and the entire time the lights are on above 50% I think it is out competing the display for PO4 and nitrates optimally.

    It's refreshing to hear post that aren't all rosey and perfect. While I don't have any electronics background and my soldering skills are less than desired, I too had problems with DIY Led. Everything went great in the wintertime but once summer/spring hit and humidity levels got alot higher, Condensation on my heatsinks etc. caused shorts and nothing but problems. I ended up going to a aquabreeder photon 48". Can't dial in the exact color I want anymore with just 2 channels and some of the lower light sprectrum are on same channels as the days which makes it really hard to achieve colors I want but overall I probably should have done that from the start. Eventually will swap some of the LEDs out on the photon but will wait a while and see how the corals react before I mod it. Will reuse the Heatsinks and such ona future ATS so not much $ wasted on my end.

    DIY LED- thanks for giving me some pause there, I was thinking of building a big ATS which would be LED driven. Burning out the drivers doesn't sound like fun.

    WP-40: One idea I've had is there was a Tunze mod folks were doing where they cut out every other row of the plastic cover for the shroud to increase flow. I've wondered if that might help stabilize flow for the long term.

    Im interested In hearing about the lime leds. I ordered some as well and read that they should be on a separate channel so id like to hear how it goes mixed in with other colors

    I build the drivers into the canopy, the new dc-dc system will be in a separate cabinet with the rest of the electronics. The PWM dimming versions at full 1300 ma I use might also cause a few more problems than the analog dimming set. The constant current 700 I use for the UV channels have none of the interior browning the dimming ones have. I have a manual 700 ma dimming unit for the fuge in the sump cabinet and it's in tip top shape even with tons of slashing salt creep. All 3 that went out where blue channels at 100% 1300ma.
    For an ATS it might be easier and cheaper but I would definitely keep spares of everything!

    Regarding limes I currently have a 1300ma warm white and 700 ma red/green channels. I will start by putting them on the 700 ma channel and going from there (I cap the 2 out at 600/500 currently so I doubt I need to go to the full 1000 they can handle.

    I built my DC-DC system and replaced my canopy. I am verry happy with version 2.0!

    WAY WAY WAY cleaner (The blue tape on cable ends in the new one will get removed once it's finalized)

    Did you end up putting any lenses back on? If so what was the par effect? I have a diy and I was thinking about 80* on just the royal blues but I should probably get my hands on a par meter instead of toasting a bunch of sticks.

    REBOOT. In preparation for my 120g build I am getting this tank up and running to re purpose as an un-medicated QT system. Tank is cycling, getting ready for the sprint frag swap!

    2 weeks of cycling. It was a pain getting DIY LEDs up and running but all things are good!
