Is Flow KILLING Your Corals?

We've been getting many questions about how to add flow to an aquarium. A wave maker can easily cause stress and even kill the corals inside of your reef tank if not done correctly. Josh explains everything you need to know about flow. How to know which wave maker is best for your tank and how to correctly use them.

"Reading the coral" That's what I was looking for. I think many of us could benefit from a lot more "reading the coral" education.

This is the best explanation of water flow I have seen. Thank you.

[FishNDive]

Man, you have been killing it! You’re videos have been extremely helpful and it’s great to hear your perspective with respect to how much time you have mastering your craft!

[captc]

Great description of a happy coral vs a pissed off coral and why!

[TXREEF]

This is such an excellent, no BS guide to flow. I love the phrase you always use, "acropora vs everything else" - you absolutely don't need to murder a mixed reef with thousands of gallons per hour!

These are kind of videos i like, reminds me of Jake Adams studio, showcasing different styles of flow in different tanks.

I do enjoy seeing the high end tanks but this was a great change of topic, and i hope to see more.

Exactly what I was hoping for. Thank you so much, Josh. The visual references are SO helpful.

Loving the mix of the educational videos with the tank tours and installation updates. Keep it all coming! WWC is such a great resource, and your knowledge and expertise are very much appreciated, especially by those of us still relatively new to the hobby.

This is the best video I’ve ever seen on flow. Very detailed.

[crumptonfamily]

It’s good to hear somebody that’s a pro that doesn’t just say it needs X number of turnover. Or just point the powerhead towards the coral. Can’t get enough of those videos. Keep them coming. I’ll keep watching for them. I wonder if you could talk about why some tanks do well at the same perimeters and some don’t and what to look for or be seasoned on for visual cues when a tank wants to go office beauty mark.??

I never understood how important waterflow needs to be in my tank. I know realized my waterflow is not adequate which is contributing to high readings of Phosphate and Nitrates, ultimately killing my corals. Lots to learn.
Thank you for putting great content.

Great Video Sir.
I think this is the best video I've watched from both WWC and Mr. Earel. You did three thing outstandingly:
1. You didn't lump "coral" into one big topic and skew the conversation towards any one group, instead you gave great advice by genus.
2. You didn't show favoritism towards one brand or even one type of application, you showed an array of pumps and highlighted where their differences are applicable and most effective.
3. You gave effective visual example after visual example. Flow is a slightly esoteric and convoluted concept. What is the "right flow", what do you mean, I see my coral moving? Answering that question only comes from years of keeping a specific genus of coral and having a calibrated eye for that animals husbandry. Bridging that gap for everyone else requires multiple specific examples either in person, or on video. And you delivered that is spades here.
Great video, and great examples. Thank you

I like how you go into detail but you still keep it in terms that newbies can understand

[ProducerReef]

This was the video I needed. I’m trying to figure out my flow now and I’m so glad this gave me a better perspective of what to do. Thank you.

[angrysackmagic]

Always a reliable source! Impressive dude!

[SunOfficial]

I think this was one of the best reefing videos I've seen in a while. Probably just saved my torch too as I noticed it had the symptoms of too high flow you described.

[thomasdirocco]

Great video Josh! A lot of people don't realize how little flow Euphyllia truly get in the wild. They're often in murky, lower energy areas vs. other small polyped corals.

[Moondoggy]

Great video, very informative, Josh is the perfect person to explain it.

[stuartharrison]

Good video, im struggling with my flow as a new reefer, got an orbit and nero 5 in a 3ft, going to try some of the suggestions 👍🏻

[Jonnyuk]

What a fantastic video, exactly what the inexperienced is looking for, hats off to you

[DarkTurtle]

Man after watching this video looked at my pump and for sure had it set up wrong! Thanks for the continued education
