290G Peninsula Tank

Figured an update is long overdue. Last week, I purchased my first batch of frags during a trip to Kamloops. Thanks again Matt.

Here they are in a little quarantine tank after i dipped and inspected them thoroughly. They are just under three stunners right now but I plan to move a couple of them up to the display today.

I see sticks!

Yup...4 of the in the display now. Having a few lighting issues. One LED went out in one of my parallel strings and the fuses shortly followed to protect the other LEDS in those strings. Needless to say...changing some fuses and troubleshooting that LED today.

Oh fun stuff...not.

Hey Mark, what's your LED set up? Fuses? Aren't you using constant current drivers? Hope you get it sorted out. LMK if you need assistance, I've got some electrical know how.

Hey Mike, thanks for the offer of help...I might take you up on that sometime. If you take a look early in my build...this DIY light uses some big drivers and I chose to do parallel strings so resistors and fuses were needed...and they worked well...I hope. Didn't end up fixing the light yet...there are still more than enough lights there to cook whatever is in the tank so I've delayed till the weekend.

I'll need to back in the thread to check out your LED build. My LEDs are hooked up in parallel as well, however not strings, rather single 10 watt multi-chip LEDs. I really should have fuses as well, but just haven't got 'round to it. I opted for 12 VDC power supplies rather than 'drivers', but am making sure the voltage I feed my LEDs is always less than the rated maximum vf, so underdriving. So far so good, the fixture is coming up on a full year of use in early April and haven't had a LED burn out yet. Only failures so far are several of the fans on the heatsinks. I have spares, so replacement is no problem & it takes all of 10 minutes. If I were to do another build using 10 watt multichips, I would use the larger heatsinks without fan now available and simply run a couple of bigger fans over the whole fixture. Probably would go with larger multichips with optics next time around as well. Three or four 50 to 100 watt multichips would be much simpler & less cluttered. They're fairly affordable these days & come in a good selection of spectrums, including multiple colours per chip.

Yeah, I love my light for coverage...no complaints at all, but it did appear that one led had an issue after being hung and that caused the "event" that the fuses were there to protect against. I have about six spare fuses and the control boards are readily accessible, so the biggest pain will be working on replacing the led as I don't want to take the fixture down.
You'll have to come by some time to check out the tank.
