Majanos are HORRIBLE. I had thousands. But ... those don't really look like Majanos to me. From pictures, they have distinct bulbs at the end. They really strike me more as a tiny baby bubble tip anemone. Still, I would not risk it. Don't scrape the Majanos off. Carefully cut a tiny bit of...

Hmm..... you might want to read this: https://char-grow.com/biochar-vs-charcoal-vs-activated-carbon Seems to me it would be good if you have mangroves or other plants. But does not seem so great if it is really just for filtration.

I am available.

Sounds like there might be a real contender for Apex. Note: Strongly suggest not putting anything critical on Wifi.

Yes, WHOLESALE ONLY. (To businesses, or people like Erin / Rich who are/were involved in the business) Not regular public. If anyone knows someone who sells to the general public, I would be curious.

Salinity probes are generally DC, not AC. As such, coupling/noise from nearby power wires and such should not make any difference. So I would not normally worry about routing of the wire. Although it still depends a lot on the quality of the actual circuit used in the sensor. Hence the "should...

I am guessing they meant UV sterilized after filtering. But the real problem: I don't think any of those services sell directly to the public. That was my experience when I poked around with that and buying a giant SW storage tank.

Did you clean it? But Apex salinity has never been reliable at all for me. Unless you have a small tank, salinity does not move that much anyway, so occasional hand testing is fine.

Interesting that the IM has 3/4" glass, but CDA only has 1/2", RSR is in between at 5/8 or so. RSR adds a lot more parts in the sump, so is not a 1-1 comparison on price. Note that 3 sides = 3 sides to keep clean. IM seems like a great deal. Lower price, thicker glass, better low height...

Regarding batteries: Lead Acid standard Car battery : Dangerous inside. Cannot deep-discharge at all. Deep cycle sealed lead acid : Good for inside, but you still cannot deep-discharge them very often or they die. Lithium-cobalt/nickel, like in laptops and cars : Expensive, high energy density...

The problem with transfer switches is that there is a short period with zero power. That will reset Apex and such. Note that most equipment needs 24V, so you do not need an inverter for that, just a clean 24V output. (The battery is not exactly 24V, it varies, quite a bit) This is more of what...

Now I regret tossing some of my AI primes in the trash in anger. Although for those, the main electronics were fried, so it would not have worked. The thing is, my AI primes had 3 problems: Fans died often. The UV burned out the lens plus caused LED board damage. The other board died as well...

The wind took my fence down. Power is fine though.

Everything seems to be a compromise... Kessil : Has fans, plus a bit blue-centric for my taste. Nice shimmer. Radeon : Has fans. Great color for my tastes. UV longevity concerns. Straton + Coral care : Great lights, but discontinued, so while possible, some risk. Straton PRO : Available in...

Appreciate the thought, but I am really planning long term. I have random spare lights for the short term.
