What filter system and pump?

Posted by Kevinf Essex (My Page) on Wed, Jul 20, 05 at 3:43
| My pond is now just over 2000 gallons and heavily stocked with Koi and Goldfish.(was only 1200 gallons but a lot of digging!)I have a blagdon 8000 pump and a Ecomax 9000 filter going through a further biological filter. The whole system needs updating as it is now struggling to keep water clean. I have to clean the pump every day and thats a chore. What do people recommend? Oase or Oasis, Bioys Set 3 or a Vortec System? I will probably keep existing filter system as well. Any comments greatly appreciated. |

Oase pumps are or were good, I havent tried the new aquamaxes but assume they will be, hence the "were".
Sorry I cant help with the filters but I would guess you will be wanting more than 5000lph from the pump which means at least a 6000lph aquamax and IMO that would be on the small side. You need to look at the flow charts for the pumps you are interested in. You also want to think about plumbing size and for at least 1000gph I wouldnt go below 1.5" |

| How many Koi and goldfish have you got? My pond is 2000 gallons and fairly heavy stocked as well but my filters are homemade or converted comercial ones. |

| When I emptied the pond to reline it and make it deeper I counted 115 fish in total.I found new homes for 40 and since then have bought 5 6" koi. Most of the fish are goldfish,3 x shubunkins, 5 x Ghost Koi, 5 x Orfe(12" long)and the new koi.I really have neither the time or inclination to make a homemade filter although I can see some advantages in this.Not rich but find you might as well buy best if possible. |

| Ok, that's an awful lot of fish for that size pond. I really haven't got much experience with larger commercial filters so maybe someone else can help. I can tell you it would be best if you could gravity feed to a vortex or mechanical filter of some kind first before pumping or carrying through to the biofilters. All those fish will make a lot of mess and you really don't want to pump it into the mech filter. It sounds like you don't have a bottom drain but maybe you could add one or retrofit one in as most comercial decent filters work best with a gravity fed 4" inlet. It will make life a lot easier as well, a lot less pump cleaning, well none really. |
