flow rate

I have 75 Gallon mixed reef tank with a sicce return pump that outputs a theoretical 950 GPH connected directly to a neptune 1" flow sensor and then from the flow sensor out to an Aqua ultra 25W UV (max theoretical flow rate of 800-1200 GPH) and then out to my display - nothing else in-between...

Hey all, PLEASE HELP so I have a 20 gallon long tank and have had a BAD velvet problem. Only one fish surviving. I have dosed with copper but hate adding chemicals to water. Would a UV AA GKM 9watt help eradicate velvet with my copper?? I know this isn’t the greatest UV for parasites, but since...

I have been trying to increase my flow rate to my Pentair SMART 40 UV. According to the documentation, a flow rate of 943 to 1574 is (*suggested/maximum). I originally had everything plumbed with 1" PVC with 1 flow sensor after the UV. I just made some changes to use 1.5" PVC going to the UV...

Hi, quite a few people ask about flow meters so I thought I would make up a simple program to manage them as my skills aren't up to messing in reef-pi. I'll have to put this in the intermediate category right now as it's a little messy changing settings but it's basically set and forget so not...

Plumbing a 75gallon display tank and I have a 1500gph pump and 1 inch drains. My question would be, is it best to do 1inch or 3/4 drain with 3/4 bulkhead lock line. Trying to have the best flow less pressure loss

I've been battling Dinoflagellates for months now and I've had enough. I already tried a blackout and that kept them at bay for 2 weeks but they came back eventually, I've tried increasing nutrients and that hasn't changed a thing, so I've given in and decided to plumb in a UV Sterilizer. I'm...

I’m curious after watching yet another reef documentary. A lot of discussion goes on about flow and what is best, I’ve noticed with seeing the corals in the wild that often the water does not move fast but is strong. Is it possible to create this flow with power heads in our tanks? Every...

I have a 25 gallon cube with a 15g sump, I have a pump that is pumping around 320 GPH. Is this too much flow for my clown pair? They are wondering around the tank, but never stop moving. I also have a cleaner shrimp, Will this be a problem for him? I’m new to saltwater, I’ve only had freshwater...

***apologies in advance - the information may be totally off*** i have tried to skim various forums and information online, but just wasn't able to find an appropriate forum which have lots of active members with good knowledge, until i came across reef2reef hello all, i've been in and out of...

This is dredging up an old controversy, but there was an Advanced Aquarist article comparing flow rates of popular power heads and there was some discrepancy between stated flow rates of Turbelle pumps and test results. Did Tunze ever change the way they advertise flow rates? I'm just...

New tank, 75g + 25g water in sump, just completed cycling with only 2 clowns currently in tank. The tank came with 2 Koralia Evolution 1150 powerheads. I purchased a Varios6 return pump... have it set on level 2 right now. The Varios6 has approx 1000gph at 5ft head pressure...I figure on the...
