JBJ 28 Gallon Nano Owners Club

HOB-1 is awesome. That's what I'm running on mine and love it.

That's what I keep hearing! I was considering a couple others, but it sounds like this one does awesomely. :]

 

[Whysoserious]

Gonna be installing mine soon over the weekend! Will post results as well.

 

[MSeg]

Definitely can't wait to see how that goes!

You know, that's actually the thread that did most of the convincing for me! :]

JBJ 28g Nano LED Pro is too bright white

JBJ 28g Nano LED Pro is too bright white

Also disconnected 2 of the 5 strips of the whites in my hood. 75 watts of non dimmable whites I felt was way too strong. Corals are now finally coloring up after 3 years. Growth has always been good but coloring was always a problem for me. So now my tank runs 63 watts rather than the original 89 watts

Hi there,

Can you briefly explain how to do this? I was thinking of getting a retrofit kit from rapid led and gutting my whole setup, but if I could just dial down the brightness of the white lights a bit, that may make me happy. My tank is only 5 months old, and everything looks good, but I just can"t get over how washed out everything looks when the white LEDs are on...and how blue eveything is when they are off.

Gonna post a pic shortly of my tank.

Thanks!

Here is a pic of my tank. Running now for 5 months. Have 40 lbs of live rock from Premium Aquatics (20 Bali Alor / 20 Fiji) and 40lbs of live pink sand. No skimmer...just activated carbon in the overflow basket. Initial cycle was minimal, and all my water quality parameters have been perfect since initial cycle. I have been very slow and deliberate with adding livestock. Started with 3 blue leg hermits and 15 snails (5 nerite and 10 Nassarius). Then began adding the other invertebrates. 1 Frogspawn, 1 Duncan, 1 Candy Cane Coral, 1 Ricordia, 1 Red Mushroom, 1 Blue Euphilia, 1 Blood Fire Shrimp. I let all of that run for about 6 weeks before adding my first fish. Started with 1 Royal Gramma and 1 Six Line Wrasse. Both have been doing very well. I recently had an issue with constant green algae all over my substrate. When I went to LFS, they suggested adding a fighting conch. I did that a couple weeks ago, and so far it has worked like a charm. I am now ready to add a pair of clownfish. (LFS had a pair of "naked" clownfish last week that I really liked...going back today, so hopefully they are still there.) I am hoping to be able to continue this operation without a skimmer. My main complaint with this tank, is the same as many have made here before...that the lights are simply too "white". As you can see, my Frogspawn and Euphilia are hard to even discern color in....but when the actinics are on by themselves...they are beautifully colored. I am thinking of just buying another regular JBJ hood, and replacing the "guts" with a kit from Rapid LED....then trying to sell my existing JBJJ Pro hood. This would allow me to not be without a hood while doing the work. I am not an electronics expert, so it may take awhile to do the upgrade...but I'm not sure.

You could simply swap out a few 14000k white LEDs with a few blue ones to get what you're looking for. I almost replaced the one that went out with a blue one. The blue ones can be found on eBay as well. Just disassemble the hood's clear plastic light cover and remove the 4 screws that hold on the reflector. Then remove the metal strip with the LEDs you want to swap out which is held down by 2 screws. It also has heat transfer paste between the LED plate and heat sink it was screwed so it needs to be pryed apart gently with a flat screwdriver. Then unplug the strip you're removing from the power supply circuit board. Now you can use a soldering iron and desoldering wick to remove solder from the legs of the LED. Then heat the base of the button LED at its joint with the circuit board it's attached to as the LED body is also soldered to the board. While the solder is liquified you can lift/remove the bad LED. You then need to "tin" the new LEDs body and then heat it and the circuit board with the iron and solder them together. This may take a few tries as the solder solidifies quickly on the board. Once it's soldered in place you can solder the legs of the LED to the boards contacts. Be sure you have the legs/polarity right before soldering the body to the board. Then reuse or replace the heat transfer paste, reattach the board/strip to the big heat sink, reassemble everything, and you're done.

All you have to do is unplug the strips from the board and they turn off.
I have dumped the jbj hood and went topless. Currently running my jbj with an AI hydra for the past 2 weeks. Love it! Here is a pic. Love being able to dim leds and adjust colors to my liking.

 

[jcs11236]

Here is a pic of old jbj hood before I sold it. I turned off 2 of the five strips. Then I added four uv leds in there place using the same meanwell driver that are lighting the 6 royals in the corners. Corals never really colored up with so much intense light. After cutting off leds I saw my corals get deep colors back

Anyone have a the clear splash gaurd for the JBJ HQI 28 for sale or know where to get one. Mine is all cracked up.

 

[Krazie4Acans]

They are available from a couple of different places. I'll see if I can find a link. I found them using Google before.

What is the best way to clean the Quartz Glass for the HQI?

 

[Krazie4Acans]

Vinegar bath will clean it quick and easy.

Do you cut the vinegar with water?

 

[Krazie4Acans]

Yes, about a cup of vinegar to a gallon of water. If it's really crusted on then use the vinegar straight and let it soak for a few minutes.
