Noticed you mentioned UV: I actually have an extra loop built in for UV. I haven't added a UV filter yet, but from what I have learned they won't work well unless the flow rate is low enough. With a dedicated loop you could adjust the flow separately. Caveat: I haven't used this thing with 3 loops yet, so don't know for sure what kind of flow through you would get. I think it would be fine though. The FX5 really is a beast.

Yeah I think it would be fine as well.

Do you like the Ista mix max inline reactor? Are you seeing a lot of bubbles in your tank? Does not look like it from the pictures?

I heard it kinda loud when actively injecting CO2? It going to be in a closed stand. Trying to decide if I should just use co2 atomizer diffuser. I read the reviews about them on this site, but like to hear from someone that has just set it up.

Few questions.

What size PVC is that 1/2, 3/4? unable to tell from picture. - Answered my own question on this one, helps to read your journal :-)
The output from your canister is that split line going to the manifold and one direct to the tank or do you have everything into the manifold? If that case does it not cause flow to be really low?

What type of CO2 reactor are you using?

Thanks again.
The filter output goes directly to the bottom of the manifold. (BTW, flow starts at the bottom to minimize the possibility of trapping air in the manifold). I am sure it reduces flow some, but i tried to minimize the number of corners and also keep the PVC diameter large for sections that carry all the flow.

The main sections are 1" PVC. The key was finding the Tees that are 1" straight through, with a 1/2" section teeing off of it. This way if I want more total flow I can open up a ball valve (partially or completely) and send the water through 1" PVC the whole way. This also lets me replace or remove the reactor or heater pretty easily while everything is running.

I chose to glue almost everything, which I may regret, but at least it doesn't leak. The only things that are screwed on are the hose barbs. That way I can replace them with different sizes if i need to. Use lots of tephlon tape and the threads and they wont leak.

The problem with using threaded fittings everywhere is that things don't come out at the right angle. You can add a union, which i think allows you to rotate it, but that adds length, and as you can see, things are already pretty tight.

The CO2 reactor is the Ista Mix Max. They make two sizes, and I think I have the "medium" one. With adjustable flow through it its seems fine. My tank is very small for an FX5 though, so if you need to dissolve lots of CO2 you might want the larger one. To decide between this type and the inline atomizers, you need to choose sides in the "misting vs. dissolving" CO2 debate. I honestly have no idea which one plants like better. Some people say its better to dissolve CO2 completely (like the mix max), and some people say it's better to send the tiny CO2 bubbles into the tank.

I like the mix max, but it does make a little noise. It would be even quieter if i turned the flow through it down more. None of the bubbles get through if the flow is right: it really is 100% dissolved.

Its just a plastic reactor, so it doesn't feel like it will last forever. I was nervous tightening the hose clamps on the fittings, but so far so good.

Thank you for sharing, most helpful. Yeah I am torn between the one you use or just setup cerges reactor. cerges reactor will cost a bit more, but might be better in the long run not sure. I want to be able to set it and forget it kinda thing, so I don't go out of town for week and worry if it might leak.

FYI, just saw this thread about the mix max:

http://www.plantedtank.net/forums/sh...d.php?t=251802

Personally I haven't had any problems with it, but you def want to read this before installing it.

What are the opinions that a FX5 might be too much flow for a 75T? I am also looking at a Fluval 406. I am going from a 26g to a 75T and going to be buying a new canister and want the best.

I am using an FX5 on a 48 Gallon, and I love it. Some people will call this way too much, but for my application I think it is about right. My journal has details. In a nutshell: FX5 is rated at 563 gallons per hour without any media. Some people target 10x tank volume as ideal turnover per hour for a planted tank.

I have an FX5 on my 75G, love it. Keep your eyes peeled for aquarium stuff on CL, I picked mine up for $125.

It looks they will release the FX6 soon:

This updated version goes along with all their other products like the Aquaclear, Canisters etc.


FX5 price drop, clearance sale on the horizon?

Thanks! Sure, go ahead and use the design. See post 33 in this thread for more details. Also my tank journal. The manifold is 1" PVC, with 1/2" for the device loops. Post pics of what you make, too!

Ive only ever owned Rena XP's and have had no complaints *touch wood* The Fluval FX-5 just seems a little too much "Oopmh" for it to be a good biological filter. If it were me i would get 2x Rena XP-3 or the "Large" as they call it now, and still have some change in your pocket.
The Brits have the FX-6 which is even more "Oomph" but are focused on being more energy efficient.

Are the ball valves for each device that will connect to the manifold 1/2 or 3/4? Cannot tell from the picture if maybe they are 3/4 with reducer connected to the 1 inch.

Thanks

Love my FX5 and would recommend it to anyone needing a filter of this capacity. My own tests tell me it pumps a little over 600 gph fully loaded with media. I won't get into the debate about Eheim vs. Fluval because it just reduces to a pissing match at the end of the day, but I chose the FX5 for the build quality and the capacity for the money. There's plenty of comparison info on the web between this filter and the equivalent Eheim and the bottom line is that you might get a slightly larger bio capacity with the Eheim, but you'll pay significantly more. For planted tanks? Why? Add to that their pockmarked customer service as of late and the price of replacement parts - meh...Fluval all the way.

Someone mentioned replacing their ribbed hoses and I seriously question why? What's wrong with them that they need replacing?

I run mine on a 40b with a DIY 1" ID spray bar.

BTW In.A.Box: I have a CFS500 too. It's not a terrible filter either. Too bad it got all the bad publicity with the top issues. For $60 it can't be beat.
