Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
If you're going to do the fix on these, I'd also suggest that you check the application of thermal compound between the finned aluminum and the flat aluminum. I believe that was the problem with my Apollos when I lost all my blue LEDs to burnout. I've found the the best bang for the buck on...
Apollo Users Beware!
Here's a shout out to the other Apollo users we have.....keep a close eye on your fans. I have now replaced all fans on my two ancient Apollos.....five of the six which had failed. HERE is the post documenting these failures.
Wow! The wood cut-out looks rather small. I think I'd try an adjustable vice grip.
If you need this, you're more than welcome to borrow. Let me know. I should be home all day tomorrow.
They appear to be the bulkheads going into the bottom of the tank. You have to make sure that there is no tangential forces on these pipes....forces from the left or right. They need to "hang" straight down.
So I was going to wait for lights out to do my final "fix" to my lights.....removing the lenses from the Mars Aqua fixture. But I didn't wait. I staged all the tools needed and pulled the fixtures off, opened the Mars Aqua, and removed the lenses, put all back together, all within 20...
Oh, just what I need, one more plug to plug in. This is what my light outlet area looks like right now! :eek:
I've already decided that when lights go out tonight I'm pulling the unit off yet again, and am going to remove the optics from the Mars Aqua. The Apollos don't have optics...
Maybe. What's PWM? Is that were something like an Apex or Reef Angel controls the light in small increments....i.e., ramping up and down?
If so, I'm happy with the way I imitate sunrise, morning, midday, afternoon, and twilight.....with my old school ReefKeeper II, and in combination...
Here's what I found out about the fans on the Mars Aqua.....they are tied into the pots that control the lights and if it's not turned up high enough, the fans do not come on. I have to turn the pot up to about 75% for the fans to come on. Not happy about that. Thinking about removing...
So my light fixtures are back up over the tank. With the second Apollo, only one fan wasn't working. I had replaced one of the fans eight months ago, and since I had already purchased enough fans, I decided to replace the two remaining original fans. So now with the two Apollos I have all...
OK! So last night I opened up the Mars Aqua. The guts of this one is slightly different than Apollos.....no Bridge Rectifiers because it appears it gets the juice for the fans directly from the LED power source. I also wasn't crazy about a simply smooth aluminum plate for the heat sink...
The best I can do is to point you to a "How To" article HERE for the ballast.
I'd also comment that if still in doubt, and the bulb is more than 6 months old, replace the bulb. It's my understanding that PC bulbs lose their spectra pretty fast.
I just can't seem to get a break with my LED's.
Back in March I posted about the issues I had with the two Apollo fixtures I had, where I replaced all the blue LEDs, because they were burnt. I documented that HERE. At the same time, one of the six fans wasn't working, so I replaces that as...
Something hit me! Here's another thought. If I'm not mistaken, this is an "in wall" build. That being the case, I would not build a free standing stand, as per the conventional dimensional stand we've all seen.
Here's what I'd do: Build the top frame....and I think I'd build the...
First off, I like the comments about scribing the base and then remove that wood....similar to fitting the sides of cabinets against uneven walls. I typically use planes and belt sanders to do this. But, bottom line, overkill for the base of the stand. No need for a "tight" fit of the...
