    DIY LED Setup for shallow rimless cube

    I started laying out the driver configuration shown here: I'm wondering if there is a better way to do it and what power supply I should use. Right now it shows a max of 36v on one string. However, the Hyper Violets show 3.0v min to 3.6v max. I'm wondering if running all of these drivers on...

    DIY LED Setup for shallow rimless cube

    Here's my updated layout. I found an 8.46" heatsink at heatsinkusa with the t-slots like the makersink, but I got it square. (8x) Cree 3-UPS (RB,RB,NW) (4x) Ocean Coral White (Red,Blue,Cyan) (8x) Hyper Violet (4x) True Violet (4x) Cool Blue Should this do the job?

    DIY LED Setup for shallow rimless cube

    Thanks a lot for the info. You mentioned this would be too many LED's, but I count 53 total based on the recommended setup for the drivers. How would you recommend scaling it back to 36? I'm also wondering about the best way to arrange the LED's. I know I need to have them as close together...

    DIY LED Setup for shallow rimless cube

    What do you think about this? I've been looking at some LEDS on a non-sponsor site. I put together a layout I think might work, but may be too many LED's. This is on a 10"x10" heatsink 13-14" above the water surface, 13" water depth. Would I need optics on this at all? Any way I can do this...

    DIY LED Setup for shallow rimless cube

    Hey guys, wondering if you can recommend a good led combo and quantity for my tank. The first and only time I tried LEDs was 2 years ago and I was severely disappointed in the look. That was 50/50 mix of royal blue and cool white. Looking at a lot of recent threads it looks like people have come...

    a real aiptasia laser

    Where did you get it and what brand is it? Are you focusing the lense until its a very fine needle point?

    a real aiptasia laser

    Is that 10mw or 10 thousand milliwatt? I have a 1watt blue laser and it burns aptasia extremely well. 10mw would only be 1/100th the power of 1w. I think 1w is going to be minimum for this particular application.

    Alkalinity Dropping Without Livestock

    .5 dKH, but there is only coraline on 2 rocks. Not much of it either. My last tank, a 90g loaded with a lot of rock and lots of acro only consumed 1.5 dKH a day.

    Alkalinity Dropping Without Livestock

    I have a 40g total volume system that has been running for 4 weeks now and I've been having to dose alkalinity without any stony corals in it and only a small amount of coraline algae on a couple rocks. I was doing some searching for this issue and I found a thread that was talking about tanks...

    Time to wait after mixing 2-part

    I'm just about out of the alkalinity portion of my 2-part. Just mixed up a new batch and I'm wondering how long I need to wait before using it. BRS says to wait several hours, but several is quite a wide timeframe. This is the recipe 1 soda ash solution. Is 5 hours long enough? Sorry if this...

    The tall back is an overflowing return. Lookup DSA Neo Nano. This is a newer style of it I think.

    Metal Halide Flickering/Pulsing

    So I have been running a 250w phoenix 14k on a lumatek ballast in a hamilton cayman sun pendant. I decided to switch to the AB 20k bulb a couple days ago and I have noticed some minor flickering/pulsing. Like it semi-rapidly increases and decreases in brightness slightly. I have verified that...
