tanah4128 Posted February 6, 2012 Report Share Posted February 6, 2012 Looking for advice and ideas to filter a Monster Tank. Tank dimensions are 12 Ft L x 4 ft W x 800 H Been told either go four FX5 or 6x2x2 sump. If sump...... How many drains to sump and what size? What return pipe size? What pump size? What media? Advised by tank builder on a 6x2x2 sump with twin 40mm durso to sump and one 40mm return with 18000lph pump. Stock will eventually be 10+ adult bass monos. Any help/idea is greatly appreciated. Thanks in advance Link to comment Share on other sites More sharing options...
Titlebound Posted February 7, 2012 Report Share Posted February 7, 2012 Holy hell mate - I'm not sure exactly what you need but if you need a hand to build it count me in Link to comment Share on other sites More sharing options...
Syndicate Posted February 7, 2012 Report Share Posted February 7, 2012 Two 40mm overflows wouldn't handle 18000lph refer to the pipe size chart sticky, your return line depends on your pumps out let Link to comment Share on other sites More sharing options...
noyakfat Posted February 7, 2012 Report Share Posted February 7, 2012 x 2 on the pipe size chart sticky... and may I just say holy smoke! That's nearly 3.5 tonnes in water alone! Please keep us posted with pics as this monster develops. Link to comment Share on other sites More sharing options...
DUCKHEAD Posted February 7, 2012 Report Share Posted February 7, 2012 For a pump that big I would be looking at 2 x 50 mm (full siphon) and prop another two as back up , with 1 or even2 40 mm returns. Have a look at bean animal over flow! Good luck I hope u get it right;) Link to comment Share on other sites More sharing options...
bristlenosejohn Posted February 8, 2012 Report Share Posted February 8, 2012 Mate I would not go any but a nexus as for the volume you are looking at these are a great way, they may look a bit $$$$ but compared to anything I would go one of these. They come in 18000, 20000 and also 34000 + but if you want great filtration then go one of these the av 18000 will set you back around the $1.5k and then go up from there. Good luck with the build and am very keen to see results mate. Link to comment Share on other sites More sharing options...
VegasMick Posted February 8, 2012 Report Share Posted February 8, 2012 Nexus sounds like a good option to me. With 3500L you would want a turnover of around 14K-18KL/Hour so the AV18000 might be a good fit. This might simplify your in's and out's as well. I guess it all depends on whether you have the space and cash for a nexus .... If you want to go a sump, I would build some redundancy into it. Potentially even build two sumps instead of one. That way if one sump was to fail / smash, the other is still going. Two sumps - one either end might make in's out a bit simpler as well. Each sump could have its own pump, air supply, heater. If you do consider going this way, something to think about is potentially plumbing the right outlets from the tank to the left sump and visa versa. This way if a pump does fail you still get complete tank circulation. Let me know when the Grand Opening is on for this monster .... I'll bring the sausages Link to comment Share on other sites More sharing options...
FIIK Posted February 8, 2012 Report Share Posted February 8, 2012 mmmmmmm still not convinced on the nexus Paul .. Just thinking about feed rates of 15 mature bass (40-50cm) + your other stocking ideas .. You will no doubt be feeding a couple kg's of food per day ... gee my 20cm bass would eat 200g a day if I let them lol therefor based on the 50L - 250g food rule you will be needing say 400L of K1 There maybe nexus models that offer that but ohhhh exxy Chat again on Friday anyway mate ... I will have a lil think in between Link to comment Share on other sites More sharing options...
VegasMick Posted February 8, 2012 Report Share Posted February 8, 2012 Feeding could get expensive at a few Kgs a day. May I suggest offering people to come around for free and feed your PB ... maybe with some live baits attached to specialised feeding hooks fastened with some non invasive retrieval device - maybe like fishing line?

FIIK Posted February 8, 2012 Report Share Posted February 8, 2012 yeah I think thats what getting lost in translation a bit here Peacock bass are massive eaters.. Im sure like many here, I have seen some smash a dozen goldies with ease & still be looking for more & of course what goes in must come out Link to comment Share on other sites More sharing options...
Syndicate Posted February 8, 2012 Report Share Posted February 8, 2012 Can you use the nexus like a sump or does it gravity feed back to the tank/system? Mick it's better to have one large sump and two pumps IMO Link to comment Share on other sites More sharing options...
bristlenosejohn Posted February 8, 2012 Report Share Posted February 8, 2012 I can see your point mate however the nexus offers some of the best off the shelf filtration around and for the dollers you where looking at spending on a few FX5 (4) the nexus is paid for and on top the filtration is great on these, in the past I have ran more water than what you are looking at doing and this housed Gibbys, oscars and a few other large americans and with this in mind thats why the nexus is my personal choice as it is a great unit. I am keen to hear if any other members have used the nexus and what there thoughts are as I could not fualt mine. Cheers JOhno Link to comment Share on other sites More sharing options...
tanah4128 Posted February 8, 2012 Author Report Share Posted February 8, 2012 John, did you use the nexus as the only filtration? Can it be the only filtration? Link to comment Share on other sites More sharing options...
bristlenosejohn Posted February 8, 2012 Report Share Posted February 8, 2012 hey mate here is a link for you to check out what the system is for the 310 and yes they do do a air pump Nexus Filter, Koi Pond and Water Garden Filtration Systems Link to comment Share on other sites More sharing options...
tanah4128 Posted February 8, 2012 Author Report Share Posted February 8, 2012 Forgot to ask, the only nexus readily available is the Eazy Pod Air from AoA. This will do 10000L heavily stocked pond and 20000L normal. The difference between the Nexus 200/300 and Eazy Pod Air is that the Nexus has a moving bed of K1 in the outside chamber and static K1 in inside chamber. The Eazy Pod Air has only static K1 inside chamber. The outside chamber is used to settle large particles. Is this still effective enough on its own to run any large setup?

bristlenosejohn Posted February 8, 2012 Report Share Posted February 8, 2012 mate if you want a cheap alternative than this system you can always go IBC's (just two) and have different filter medium but then again this takes up more space than a nexus but I never had any issue with nexus as they cover everything for most fresh speices.

tanah4128 Posted February 8, 2012 Author Report Share Posted February 8, 2012 So I guess my question would be... The nexus or Eazy pod will be the same as having chambers of jap mat, matrix, noodles, clay balls, sponge, Dacron etc? A replacement for a fully functional sump?

bristlenosejohn Posted February 8, 2012 Report Share Posted February 8, 2012 It is mate however I have found with fish that produce alot of waste this system is easy to maintain and keep tank looking great and fish in top condition and its compact Link to comment Share on other sites More sharing options...
