Inline filter system and tanks

| Hi,
I am thinking of getting a new filter system so could I use my current ecocell 2200 filter with no media in it but use it as a settlement chamber by removing the internal piping so water is pumped into the top and then also flows out at the top into another filter so sediment falls to the bottom. Would this work?
Failing this I might attempts ot build a vortex chamber but I cannot find anywhere online which sells "bulkheads" and normal black tanks which i can use to make filters out of. Where can I buy these from or has anyone got one I can buy?
Thanks,
Daniel |

I am tiddly, Star trek, beer and curry, so excuse any faux pas,
re bulkheads, source depends on pipe size,
32mm and 40mm from B&Q, plumb/ing world etc,
2", 3", 4" etc, http://www.koicarp.net/pvc_plumbing/connectors.html
however the owner is very ill and family are running the buisness so they are somewhat distracted,
alternatively look for some of the buisness posters on http://www.yorkshirekoi.co.uk/ or do a web search for kockneykoi
Re settlement tanks, various relative sizes are quoted for SC's, the origin of some of these I do not understand, the one that makes sense to me is a "dwell time" of 15min, mean 1/4 the flowrate, ie if you pump at 1500gph then an SC volume of 375 gal. The reason being that the dwell time implies an average speed through the chamber. This obviously equally depends on the area of the 'channel'/water-surface-area of the chamber, ie a 375 gal chamber could be made from 1" pipe but the speed through the 'chamber' would not favour deposition.
Given that information I would suspect that a Hozelock filter tank would be next to useless as an SC for all but a puddle. I have a Hozelock something 2?00 filter and I would doubt that that would hold 20 UK gal, 3.2cu ft of water brim full, which would give a flowrate of 80 gph for it to work as an SC. There was an 'in depth' discussion on the forum koi phen, remove the space between koi and phen when looking for that forum.
You could also try browsing the koicymru site rather than the forum. Vortexes, I dont know sizes and flowrates etc but look at cold water cisterns for tank or 50/55 gal barrels, the latter may be free from some sources but find out what was in them first. The new filter I have added is a 3'x2'x2' cistern I spotted on a skip and ASKED about, reclaimation yards, or maybe council refuse tip |

| Hi, If I have a 3/4" inlet can I use this? http://www.plumbworld.co.uk/733-8300 or http://www.plumbworld.co.uk/733-477 Where would the pipe connect to? Would I have to just shove it in or would I have to attach a small length of PVC pipe it then fix on my corrugated pump hose? Thanks, Daniel |

| I dont know, if you are using 3/4" hose then I suggest 19mm overflow solvent weld, for that size Marley and probably all the other manufacturers make a female connection tank connector, sovent weld a short length of 19mm pipe into the female leaving enough pipe to act as a male stub over which I think 19mm-3/4" pond hose fits, note I said I THINK. B&Q sell the marley stuff and may be more suitable to your needs as you can browse at your leisure, a trade centre may be p****d off with a teenager not knowing what he is after or what is available. Take a piece of hose with you so you can try the fit of hose and pipe. BTW you may need an adult with you to get the solvent weld glue. All that said 19mm is very small, there are adaptors for pipe to step up to 32mm and then 40mm and it might be worth your while plumbing as big as you can go and stepping down where required. |

| Hi, Cheers, its just all these pipe names and types confuses me, so solvet weld pipe needs the solvent glue to fit them together? Ok so I can fit a settlement tank say 40mm (1 1/2") tank connector followed by a small piece of 40mm pipe and a step down pipe to my required di. pipe to enter the biofilter. Thanks, Daniel |

| So is solvent weld the most common rigid pipe that is use to build ponds? also will ABS and PVC fittings fit the solvent weld pipe? Thanks, Daniel |

"So is solvent weld the most common rigid pipe that is use to build ponds,"
dont know if the most common but arguably the best type since the joint are the least likely to fail. BTW be generous with the glue and do a few practice joints before you make proper joints. Measure 4 times before you cut. "so solvet weld pipe needs the solvent glue to fit them together? "
yes "Ok so I can fit a settlement tank say 40mm (1 1/2") tank connector followed by a small piece of 40mm pipe and a step down pipe to my required di. pipe to enter the biofilter." Yes but if possible step down as close to the biofilter as possible. |

| ok cheers, a lot cleared up. Thanks, Daniel |

| 1 more question. Will 40mm flexible black hose fit over 40mm solvelt weld rigid pipe? Thanks, Daniel |
RE: Inline filter system and tanks
| | |
I dont know, sorry, I have '40mm' hose that is probably 1.5" hose rather than 40mm, 40mm is 1.57" and that will fit over 40mm pushfit which is, from memory, smaller that 40mm solvent weld but it was a heck of a struggle. If your 40mm IS 40mm you may find it quite easy.
32mm is much closer to its imperial equivalent, 1.25". |

| My previous reply have read incorrectly, so to clarify, 1.5 inch "will fit over 40mm pushfit which is, from m....." |
