flow

  1. Equipment
    Hi, About a year ago I built a Cerges reactor and attached it to my Fluval 206 canister. After about 10 minutes there was no flow out of the canister. I had assumed that this was due to the canister not having enough head pressure. I took it off and stored it away until I had a bigger...
  2. Algae
    I'm trying to increase flow just enough to make the plants in my tanks move, doesn't need to be anything more. I need something safe, need to keep the "small creature" getting caught up in impellers to a minimum, thinking small pumps might be better than a power head? I've got a 29 & a 55gal...
  3. Shrimp & Other Invertebrates
    Hi, I'm running a 100l shrimp tank, well balanced natural/Walstad tank style. Which means it has no active filter. But not too long ago I came across some Bamboo Shrimp / Wood Shrimp and they do like some flow! I introduced a little pump, photo attached. I got this pump because it is inside...

    Hey everyone So I have a Juwel Vision 260 where I can't optimise my water flow because of the pre-existing gaps for cables at the back of the aquarium. The in- and outflow tubes are connected with plastic square-U-shaped parts (by Oase) and there is simply not enough room to fit both the in and...
  5. Plants
    Hello, everyone. I'm putting together a 46-gallon setup and I've had an thought that's a bit unconventional so I immediately came here. I've scaped the tank so that there's an outcropping of stone extending towards the center to mimic a cliff-of-sorts. On this, I'd like to plant a Red Dwarf...
  6. General Planted Tank Discussion
    I want to get some glass inlets and outlets for my aquarium, but I will be keeping dwarf pufferfish so I don't want the flow to be too strong. I will also be running CO2, will the increased surface agitation from the poppy style pipe make the CO2 to exchange into the atmosphere faster? Thanks :)
  7. General Planted Tank Discussion
    I have a 12 gallon long with an eheim 2213. I just stocked it with some rummynose tetras and noticed that they have trouble swimming against the flow created from the intake. Theyre constantly facing away from the area around the intake, they almost look like salmon swimming upstream. reducing...
  8. Planted Nano Tanks
    After seeing clean nice planted 1 gal picos, wanted to try it myself, missing obvious points: they had no heater and no source of water movement. Now I have plants in 18x6x7 in. rimmed rectangular tank, 25W adjustable Theo heather and smallest Tom Dive Clean Mini Internal Filter, 48 gph...

    Hi, I'm new to the forum. I couldn't see where this might have been addressed before but when I do a tank clean and switch my filter back on, I tend to lose abit of flow on the filter. You can tell because Co2 bubbles stay on the surface when they would normally get pushed around. Do I have to...
  10. DIY
    I'm having issues with mulm build-up and stringy algae in my 5.5g and I'm thinking the water flow is part of the problem. I have an Aquaclear 20 on it right now and just got an Azoo 180 nano powerhead. I would like to put the filter on the side of the tank, but my light legs take up too much...
  11. Equipment
    I was given a used Fluval 306 from a friend awhile back, but am still using a HOB (Aqueon Quietflow 20) in my 20G long planted tank. Along with a Aquaclear Powerhead 20. Both of these rate at about 125GPH or a combined 250GPH. After a little research I have learned that a canister filter is...
  12. Planted Nano Tanks
    I have a 10 gallon mid-tech tank with a male crowntail betta. It has an AquaClear 20 HOB filter. I've found that if I run the filter at full strength the returning current is too strong for the betta. For the first few months I just ran it at half strength, but that felt like I was wasting a lot...
  13. Equipment
    I have found out a website where you can calculate the flow (Q) in scfm (standard cubic foot per minute). But to do that you need to fill in some data first: 1) Cv (flow coeficient) 2) Upstream Pressure 3) Downstream Pressure 4) Temperature 5) Specific Gravity for your gas ("Carbon Dioxide" in...

    Hello all, I'm still setting up a 92G corner tank and am concerned about water flow. It'll be moderately planted with val, Amazon/Kleiner bar sword and crypts. Anyone have recommendations on a powerhead or circulation pump to prevent any dead spots? Or should I just aim the return hoses (from my...

    Hey guys, I got a fluval u1 for a 6.6 tank and has the perfect gph for my planted tank. I was just curious if I lowered the adjustment flow, does that lower the gph? :confused:

    Hi All, I have the bug and am already setting up multiple tanks while I wait for my first to cycle:icon_lol:! My husband is not only supportive, but found another spot in our house and bought me the tank I have had my eye on! He's amazing! So my question(s). I have a Fluval 305 that I...
  17. Equipment
    Greetings, I'm trying to get parts together for a weekend project to plumb my Fluval 206 canister to a 30gal I haven't yet put to use. Any advice would be greatly appreciated. As I understand it: My 206 canister hoses are 5/8" ID and it flows 205gph. Anyone have any math on whether or not...

    Hi everybody! I'm new here, and am in the process of learning the ins and outs of fish husbandry within a planted tank. I have a new 2213--less than a month old--and, all of the sudden, the outtake flow has become inconsistent. I've tested it in my sink, and the rate is initially slow, then...

    I have a 3 week old Cascade 1000 cannister. It has had a serious decrease in flow. I have cleaned the media in tank water, it was not that dirty. I have tilted it, as I wonder if there is air in it. Still no increase. Wondering if the impellor may need to be cleaned off. Not sure how to do...

    Hi everyone! I'm new here, but I hope I am going to fit into the community fine. English is not my native language so sorry for the mistakes in my sentences. I'm new to planted aquarium so naturally I have a questions. I have 240 liter (4 foot tank) tank running at the moment with crystal...
