    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.

    Plumbing Flow Rate

    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...

    Flow Meter Addon for reef-pi

    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 for 2 returns, 1inch or 3/4

    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

    What size UV to save me from Dinoflagellates?

    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...

    Flow in your tank

    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...

    To much flow?!?

    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...

    Tunze Turbelle flow ratings

    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...
