Flow Indicators

immo · Apr 24, 2023

So, I was watching a youtube video from VCA, and in the background, it looked like they had these little paddle wheels mounted in a tank with their RFG (I'm assuming to demonstrate it's random flow). Did a quick google search, couldn't find anything. I really haven't seen anything that helps people get a visualization of the flow in their tanks. Other than throwing something like AB+ in there to see what it does. Does anyone know of any kind of "flow indicator"? I have a 3D printer, and can do some modeling, and most likely I could replicate what I seen in the video, and possibly even improve on it. Would something like that interest people?

You mean something like this but open for aquarium use?

That you could moove anywhere and act like a wind turbine so you can see direction and speed of flow into the tank. Im surprised i never seen that so far

I like the idea -- never seen one either.
I've been trying different lengths of dental floss tied to stainless steel straw for assessing flow but it's pretty LAME.

I've been searching for something like this pendulum device that swings back and forth, found several on YouTube. No places by me have them or can get em. Cant find em on amazon or ebay. Trying to find that logo to search that company.
So many people say just put your hand in the tank in front of the pump to see if its working. SMH. Idiots

If you're talking about the nori clip, just looks like a normal one, like this:

Nori Clip

I don't really see how that's too useful for gauging flow other than direction though.

Lol ... that's all they are? Holy cow what an idiot I am. I've seen them moving back and forth so fluidly, some faster than others, I thought it was showing how strong the current is. Most times there's no food attached, but in the last clip it did have nori attached. That's freakin crazy. I have a clip, but it doesn't swing at all. It stays exactly how I adjust it.

Lol . That's great, for days I'm looking for something diff than it is. Thanks EricR. I found the same on on Amazon. The mega vegimag. https://www.amazon.com/Two-Little-F...ield-lbr_brands_browse-bin=Two+Little+Fishies

At 38 dollars its alot more than the cheap one I have but much nicer, magnetic and free swinging. Anyway I can rest now, thanks!

Search for portable water flow meter/indicator. Used for river/stream/environmental water monitoring. Usually consist of a long stick with a submersible vane. Usually listed on environmental monitoring equipment companies, so they can be spendy, few hundred into thousands.
