    Default New Tank - Sump vs Canister Questions

    I am setting up a new 135 gallon discus tank. Since I am a newbie, I obviously want good filtration, but I also want a quiet tank. I have several questions under each option and will number them in the hopes that people will be nice enough to respond.

    Sump - I would plan to use an Ecotech Vectra M1 which has a stated GPH flow of 2000 (probably somewhat less in operation). I know discus don't like a lot of flow but I would assume that there is a tradeoff in the effectiveness of the sump with lower flow rates.

    1. What is the recommended gph/turnover rate that I should not exceed.
    2. What model of Sump would be recommended? I am a terrible DIY guy, but the premade sumps mostly seem to be made for saltwater. I have looked at the Seamless Sump by Custom Aquariums but it is expensive and I'm not sure it holds enough media.
    3. What is the best overflow method. I have a bottom drilled tank now with an internal overflow box and it is noisy. Are there recommended alternatives?

    Canisters - I would use two canisters and was thinking of the Eheim Pro+ 600 which has a GPH of 312. I have one of these now and it is very quiet. I know Fluval FX6 is well liked, but seems to be louder.

    4. Would the Flow from the 2 Eheims be about right?
    5. On one of the canister outflow lines, I would install an in-line heater - either the Hydor of the ISTA - any recommendations?
    6. On the other canister, I was thinking of installing an in-line UV filter. Do I need this and if so, any recommendations?

    Thanks for your help!!

    I use sumps for my discus but all they are are cheap 1 per gallon aquariums 20 long from petco that I load up with 4X 2 inch thick foam sheets I get from Swiss Tropicals. Water enters one end....exits the other....not drilled or anything just basic pvc pipeing. I use a prefilter sponge inside the tank so I rarely need to mess with the sponge in the sump. I think the 20 Long work great for tanks up to 75G.

    Don't bother with UV, just do lots of water changes.

    I have a 200 gallon fully planted tank, and I run TWO Fluval FX6s. I find them to be extraordinarily quiet. Both are filled to the brim with Biohome Ultimate media in all trays. The FX6 has so much filtration, that you can actually remove a few of the foam filters to make room for more biomedia.

    Now that my tank is 9 months old, it seems to have fully cycled. All I have to do is one 75% water change per week. My ammonia is always zero, as are my nitrites. My nitrates never get above 10 and are usually hovering between zero and 5.

    My 2c.

    Thanks. I just ordered a ton of Biohome and will use it in an Eheim canister and the sump.

    Hi Ggilles,

    As you are running two FX6 canister filters I would like to ask your opinion / experience please - I am right now upgrading my filtration on 240 gal low tech tank - so far running over ten years with Fluval FX5 plus Eheim Professionel 250 - really happy with both - now adding new Fluval FX 6 to beef up ahead of adding Discus to my tank - lightly planted (after I pulled out all the heavily growing Valisneria which was trapping a lot of hard to clean crud and left there only very well grown up Echinodorus varieties easy to clean around) and a lot of bog wood inside.

    My question is on appropriate flow rate and actual current created in the tank - two options being either to connect each FX filter independently in parallel setup (two intakes and two outputs) - than I would get turnover rate of about 8x per h, but I worry about having too strong current in the tank as Discus may not like that strong flow - so I think about putting both FX filters in series (one intake and one output) - from tank to FX 6 - beefed up with PondGuru upgrade kit - coarse + medium foams and rest being 5 kg of his Biohome Ultimate media - from there to the intake of original FX5 - loaded to the max with Biohome Ultimate media only - no foams needed anymore here as mechanical filtration will be taken care of already in the first FX6 filter - and from there back to the tank - this would give turnover rate of about 4.2x per h.

    Parallel setup - higher flow rate, full redundancy if something may go wrong with one of the FX filters the other still running full speed- maybe too strong current in my tank?

    Setup in series - lower flow rate, partial redundancy - if one FX pump may fail, the second one will be still able to pull the water through both canisters albeit at lower flow rate, regular maintenance needed only on the first FX6 in the series - where mechanical filtration happens - no need to mess up with the second FX5 filter and leave bio-filtration there undisturbed.

    Is there anything I might be missing - why the in series setup may not work as hoped for? Or should I not worry about too strong current / flow created in the tank with both filters running in parallel setup - plus the Eheim 250 still there as well?

    Thank you - and anyone else - who may help me with your expert's advice!
