Same exposure for the water going through, yes. But assuming you are saying the setup with 2 UV’s is twice the wattage of the 1 UV setup, the one going through 2 UV’s at twice the rate is treating twice as much water/pests per unit time, and also importantly giving the pests half as much time to...

Having a high coral-to-water ratio causes instability since the consumption and replenishment go up and any perturbations have larger effects. You can decrease the amount of consuming coral, increase the amount of water to have more buffer against changes, or get more serious with auto testing.

Toss it. Or get the company to replace it. I like K&J as above. Also I find the Oceans Wonders coated magnets to be great and generally super useful around the tank-...

Taking anything to the logical extreme will make it seem ridiculous. Of course there’s more nuance than what you read as a guide from BRS or where ever. UV causes DNA breaks. Some breaks are bad for survival or reproduction, some aren’t. Many are in between, they are bad in certain...

It’s UV exposure- intensity level (watts) x seconds exposed (inverse of gph). So having them in series means twice the exposure, the equivalent of running half the flow rate (like Randy said). That said, having them in parallel is probably just about as good since on average you’ll be delivering...

Sorry I don’t have anything useful to add in the electrical engineering department. But for me the takeaway is that you unfortunately are having to deal with crappy products and apparently no manufacturer support and I should stay away from the brand(s) in question. So to clarify, these are...

Too bad the police are not interested in solving and prosecuting property crimes. Even if we all said, “Hey that’s Jimmy!” nothing would happen.

Eric’s just gonna do a partial tank breakdown while Joel isn’t looking. Frag ‘em up, move ‘em out.

I never used the wifi InkBirds because they get poor reviews. I have a bunch of the old school non-wifi ones and never had a problem with any. But all temperature controllers I use have backups carefully designed to avoid fail-on, fail-off, and gross miscalibration failures.

What are you suggesting is better? Ranco’s specs are less accurate and don’t show decimals, for comparison.

They look accurate to me. It’s easy to add a calibration factor to make them all match a reference thermometer or just so that they all match each other, which is basically as good for as little variance as there is.

Just speaking for myself, it wouldn’t be one or the other, it would be both. Not much overlap in what I get out of BAR vs what I’d hope to get out of the app. Anyone here using it? Care to share thoughts? I imagine the hot-takes that influencers give after a couple min would be less informative...

I saw this was promoted by Hilary from saltwateraquarium with a video interviewing one of the devs, and reminded me of it again. Now that we are a few months later I wonder if anyone has any additional experience with it? I also noticed they added a 12-month plan for $25, which is more...

Glad to hear it

Yes sorry I didn’t mention up front that it’ll be 1 cut in-tank (per session) then fragging up out of tank. And will use iodine for the frags.

I actually really like it. More than other much more expensive coral I have. Just too big of a crown at the moment.

Hey all. I have this huge bright green toadstool leather coral that has grown great but is getting too large. Pushing and shading other corals too much. I need to trim and frag it. I’m not particularly worried about the actual trimming and fragging, planning to use sharp stainless steel...

To reduce the chance of free lanthanum escaping into the tank, you want to dose very slowly over long periods of time, so hand dosing is probably impractical IMO. The sock or skimmate both collect the La only after it reacts with PO4. Unreacted lanthanum goes right through. So dosing more than...

I know at least 1 home based seller uses the bottoms of plastic cups like drink cups, deli cups, or yogurt cups as the molds for making cement frag discs. Any reason that wouldn’t work for the aragonite concrete approach?

Thank you for explaining!
