flow control

Question about flow for a mixed reef, my tank is a 210 - 72x24x29. I have mixed corals included a few torches and lots of negative space aquascape. I have my return pump maybe 800-900GPH at the nozzles. I added extra nozzles to break up that flow. All my torches in the bottom 3rd - 3-4 inches...

Long story short, I have a 20g long with a Nero 3 and an AI Blade. They’ve both been working well, and I haven’t really had issues with them. My tank has been running for a few years and was doing great until life got busy (kids!). It didn’t get the attention it deserved for a while, and I’ve...

I am planning a 5 ft x 2 ft x 1.5ft LWH FOWLR build and would like to have a closed loop since I do not want power heads for aesthetics reasons. I am aiming to have around 1500gph an will be using an old 40 gallon aquarium as a sump and I was wondering if that would be ok in handling the flow...

Hello I recently set up my first saltwater aquarium and I’m having issues with my flow pump. While cycling the tank my flow pump was blowing the sand around my tank enough that it was causing it to pile up and even have bare glass in some places. When I added my first fish, a pair of clowns...

Hydros Wave Engine V2 for sale. I used this with two Maxspect 350 Gyres and a Reef Octopus Octopulse 4. Setup and control is super easy and there are multiple flow modes. The only reason I am selling as that I have an odd-shaped tank and couldn't get the flow patterns I wanted so have...

Hi all I’ve added a jeboa MOW-5 to my fluval evo 13.5 gal/52 liter tank as I’ve recently added gsp/ Kenya tree with a max flow of 500 to 5000L/H just curious on the best settings/flow for this pump it has sine wave mode which can adjust the frequency of the waves and also the correct position of...

Hi all, this is my first time posting here. It is a waterbox 15g which i have taken high budget to go sps route with xr15. I have got 2 clowns in there since yesterday and i think the flow might be too high and wrong position. Where do you think would be good to place it and what power? The...

When I have the COR pump running, lets say at only 5%, the tank level is fine (even though 5% seems low but doesnt make a huge difference to lets say 20%). However, when I turn on the UV sterilizer pump, the display tank overflows. What confuses me is that the flow rate on the UV sterilizer is...

So I have a SICCE Extreme sdc pump and a voyager nano 2000. I’ve recently added some LPS and I feel like my flow was way to strong as they had some difficulty opening. I want am going to remove the voyager and just run the sdc pump and trying to get the right moderate flow for my torch and...

I read that you’re supposed to put Forest Fire Digitata up high with lots of flow and I did that but it seems like the polyps aren’t opening….perhaps too much flow? Where do you put your digitata?

Hello fellow saltines, I tried searching for posts about managing flow but couldn't find anything related to my issue. I just setup a 5g top fin AIO. The tank currently has one rock and a Hi Fin goby/Pistol shrimp pair. When I started the system up my sand was smooth and even across the tank...
