O.C. Nano display tank

[OceanicCorals-Eugene-]

update time.

Paul decided to change the bulb out to the 12K without my permission...i hate him lol jk. The 12K bulb looks pretty nice, definitely alot less blue but still gives the corals that pop in color that everyone wants. Water has cleared up but we have some little flatworms issue, the non acro eating ones that just sit on the glass and looks hideous. A new stand was made for the tank so that people no longer have to bend down to look at it.

Other then that not much change, the colors are staying pretty good. The valida has gotten some of its colors back from being bleached under the 400W MH. But all corals seems to be holding its color. temp stays steady at 79.4-80.3 throughout the day. Thats how much heat is being transfered into the tank

More update to come next week.

Great little tank. Very interested in the lighting....whats the light spread and penetration like on that LED spot light? does it just fit into a normal bulb socket?

great little shop you guys have there, great looking corals and tank.

i would say the spread of the spotlights are roughly 1ft x 1ft range for the 27W version and abotu 10"x 10" for the 15W version. Penetration on the LED are fairly good, with the light at 10" above the surface and the PAR meter 10" below surface we were getting ~250PAR for the 27W and ~160PAR for the 15W. Considering MH coverage is roughly 24-30" depending on the reflector, these little bulbs are pretty up to par(no pun intended) in terms of area of coverage and PAR value(almost equal to a 250W if not equal).

And it does just fit right into an average lighting socket so if your socket breaks somehow something at homedepot or hardware store can fix it.

Thanks! Glad you liked it, come drop by again once we get more things up and running!

Looking Good Eugene! Great to see a more affordable option in LED spots.

Here's a review of the PAR38 lamp and its PAR coverage at varying distances THROUGH THE AIR:

FWIW, the coverage is pretty pathetic but would suffice for spotlighting - certainly not a MH replacement.

i don't think it's fair to say coverage is pathetic or to compare them directly to MH as they aren't intended to replace MH over larger tanks. LED's can produce performance equal to MH over a small area which is why you need a large array of LEDs to cover a larger tank (I'm using 80 LEDs to cover my 48"x18" 75 gallon). But for nano tanks or spotlighting these Par38 type bulbs are a great option.
