flow

I see a lot of confusion about flow, so I thought I'd share a few of my articles from my own website here on reef2reef. Here's a link to the original: https://seahorsewhisperer.com/flow-in-a-seahorse-tank/ “Flow is one of the most important, and yet least understood aspects of a seahorse tank”...

Ok I bought the Apex FMK (Flow Monitor Kit) and installed the 1/2 flow sensor in line in my return hose to my DT . I have a EFLUX return pump that pumps up to 1050 gph. Before I installed the senor I ran my pump and 70% power and everything seemed to be good. I could see where it raised the...

My corals so far had been high light and flow, but how do you know your coral is getting too much flow/light. I know too much light can turn corals brown because of zooxanthellae. What about flow? Do they close up with too much flow?

I will be setting up a 65G due to custom built tank, this is my idea of setting up the flow for the tank Pump : maxspect gyre 230 (2300gph) or larger. The tank is 36” wide and overflow is 24” wide. So I have around 6” on both side from the edge to put the magnet. This pic below would it be too...

Contemplating a reasonably large peninsula but a little worried about getting flow at the top end of the tank without effecting the aesthetics of the tank itself too much. How have people been doing it. Photos and ideas would be appreciated.

Hey guys I recently purchased and set up a maxspect gyre XF230 and was wondering if I can set it up so it runs on higher power during the day and lower power at night? I don't want to do it manually everyday in fear of wearing out the controller. Please let me know, thank you!

We have been playing around with ways to show the unique flow pattern the Random Flow Generator Nozzle is capable of producing. Because it works through fluid dynamics and has no moving parts, it’s been a bit of a challenge because anything you put in the water such as micro beads, tends to...

Something that I've been thinking about but haven't put much time or effort into researching is flow inside the tank. There is much debate on what flow should be going through your sump, fuge, and powerheads. We have nifty inline flow meters that will help diagnose issues with our overflow and...

I'm just setting up the refurbished tank to Triton spec's and have a query with regard to flow. I have a RedSea Reefer 350 tank with a Synergy Triton sump. I have an Octo Vaios 8 pump and using it to feed the return via a manifold that has a chiller, and 2 reactors attached ( ROWA and carbon)...

How can I get good circulation with Apex WAV for a 120 gallon peninsula tank? I don't want to obstruct the view from three of the four sides. I will have an external overflow.

Hi All! I am having a little flow issue in my 65 mixed reef and was having sand piling up on one side of the tank bottom. So I bought a 2nd MP40. I have the ReefLink set up and both MP40s are recognized. Now to figure out the programming... I'm looking for a starting point that I can tweak...

I recently started my tank and finished the cycle (yay!) with 100% of my rocks and sand coming from an established aquarium that was 5ish years old. I have a 2100 gph wave-maker, two 825 gph heads, a 300 gph canister filter and a second filter that is 525 gph. This is not counting my 225 gph...

Looking to possibly upgrade my flow in my BlueWorld 180. Right now I have a Tunze 6105 on each side of the tank in the back, pointing up The program for each is complex via Apex. For some time it will do 100% on one, 30%on other, sometimes for 3 seconds, alternating, some times for 10 min as...

I want to see different videos about Low, Medium and High flow in your tanks and pump placement.

Ok, got a question about UV sterilizers. I'd like to run one for bacteria which would be at a low flow and... a separate one at high flow for algae. Has anyone done this? Is there a benefit/problem doing this? Do I just adjust the UV to mid flow to get both? Posted this in another forum but...

Big shout out to @CJs Aquariums for spending the time to come up with the settings for the standing wave using the gyre pumps. CJ and I are both running 230's on our tanks, his is a 120 gallon 4x2x2 and I have the Reefer 250 36x20x21. Our schedule's are a little different and I obviously use...

On an sps dominant tank, how many times an hour are you turning over your water? I have heard 10 and I have heard 20. I run 2 3k cures and 2 mp40 for in tank flow on a 6 foot 165 gallon. I am looking yo upgrade from a mag drive to a dc return pump. I have 2-3/4 return lines plumbed to the tank...

so I am getting a koralia evolution 1500 gph for Christmas.. tank is a 90g. probably 75-80 gallons actually in the tank due to displacement of sand and rock. this will give me approximately 20X turnover in the DT softie/Zoa/Leather tank so where should I place it.. Back wall middle facing...

Just like the title says, how much flow do you run through your return pump and back to the display tank. There are a number of opinions on how much GPH you should (or shouldn’t) run through your filtration systems, but really for this poll, I’m just interested in how much flow, in approx. GPH...

So I’m just getting my DT up and running and into my third week of the cycle. Everything is normal and as expected. apex installed and working well BUT... I opted to go with the Fiji pink sand in lieu of larger grains thinking that it would be best for sand sifter gobies and bottom dwellers...

I just got a small sebae anemone. I put it in my 180g display tank that has two Tunze 6105 powerheads, a decent amount of flow. I created an area for it with three pieces of live rock in a square pattern with sand in the middle. Not sure if it moved or got blown by the flow, but now its in...

Sitting here wide awake crunching numbers, flowrates, and head loss! 29dt 20sump What flowrate do I want going through sump? My flow rate in the dt is over 10x. I’m talking about the flowrate going through the sump to facilitate the best filtration? I’m thinking 29g times 5= 145gph? Or 29dt...

Do you run the Random Flow Generator™ Nozzle in your aquarium - want to show it off? We would love to see it. Post pics of you tank - be sure to include shots that show your RFG Nozzle. Videos are great too. There is no better way to show the flow than with a video :) You can learn more abtou...

This is my full siphon on Synergy overflow. Is anyone running a flow sensor on their full siphon line? It seems no matter how closed down my gate valve is, I get sharp drops in flow. No air is making it into the lines, I have a steady trickle on the secondary drain line.

Im wondering which return pump i get. I am building a 40g. With the sump minus sand and rocks i should be at +- 60g. It will be pumping up about 3 1/2' - 4' head. What should turnover w/o power heads be. Ive heard 4times on the low end and 10 on the triton method. What are you all running?
