| With your size of a tank, you should go in for a pond filter. rate of flow will range between 7000 to 15000 l/hr or even more if you want. You will have to order one from abroad. You will find a lot of choices if you GOOGLE for it. They are even available on Amazon.com. Just keep the customs duty (34%)in mind while ordering from Amazon (if you plan to order) |

| Even you can DIY it with a good quality water pump. The capacity should of course exceed 7000 liters p/h. |

| You are somewhat right Saurabh, but the only problem with that would be that you cannot leave it on 24x7. You would need to monitor switching on and off. |

OASE has good pond filters. The main dealer is in Bangalore. Rufus was also dealing with OASE filters. His contact is 9845039631.
I hope I got OASE right! 
Since you have already ordered an Eheim there's not much we can change. |

@madan
Ya i have already ordered the eheim,i also have a dolphin filter.Both of which will filter around 2950 lts/hr. I think it will be sufficient, what do you think? |

Hello 
First of all you have a INSANE tank nitishi..
big time envious LOL
You can also look at adding a external UV tube with your external canister filters .
Get a good big one like a 36 watt UV or something. Can also be hooked up to a simple powerhead.
2950 lt/hr accordig to me is not going to be enough sir nitishi. You should atleast have 2 times the turover of the volume of your tank per hour at the very minimum.
look at adding a 5000-8000 lt/hr pump/filter as well if possible .
Cant get over your tank specs hehehehe . Please do post a pic for us
Dying to see that monster |

When you have spent so much on the tank and everything else, invest in a 1 KVA servo stabiliser too. It costs about 3.5K. That will protect your equipment.
I use a 1 KVA servo stabiliser for my tanks as I have 6 Eheim filters running, all my lights run through the stabiliser. When voltage is very low the rotor keeps banging on the sides and gets damaged, the servo stabiliser will protect you from damage. |

Sorry for the Hijack
@Madan
For running the filter alone wouldn't an online / line interactive UPS of smaller capacity suffice? Wouldn't that give you a safety margin for power failure? |

I am not worried about power failure. The Pumps stop and there is no damage.
My worry is low voltage, in the region of 140 V or less which we sometimes end up with for a few hours.
Secondly this low voltage damages my MH in no time, that's why I have a 1 KVA rating servo stabiliser. |

Hi Nitish,
I've used the CF-2400 (@2400lph) excellent performance, but had to be replaced by an Eheim 2260 after 2.5 yrs. (leak problems).
For a beginner & amateur - it will be tedious to open for servicing. Levers can break, if not careful.
Spares availability – poor.
In short – excellent performance & poor on reliability.

UV is beneficial for outdoor ponds / FW aquariums. UV, along with destroying algae spores, also kills beneficial bacteria. It should be used with caution on indoor FW Aquariums. Its use in marine aquarium is out of context here. |

Hi Sumant,
I don’t see any issue is keeping a 7000lph or even 15000lph pump ON for 24x7. If it is meant for biological filtration it has to be on always.
I completely understand power outages are likely & that’s something not in our control, but if you wish to have 100% uptime, opt for an inverter. |

Hi Madan,
That’s very true they are only good as POND filters.
One of my clients insisted that he’d get a filter for his aquarium from abroad & he got an OASE FILTOCLEAR 6000 with AQUAMAX 3500. I’d educated him on media option, but he was still willing to try.
We installed the filter & it took over 10 days for the water to clear out.  Well, at the same time at 18†depth, the water appeared crystal clear the in 2 days. But through 5’ depth & 10.5’ length vision was very poor.
Reason –the canister only houses Fine & Coarse Sponge in alternate rings – STACKED & water flows over various media simultaneously outward > inward flow & that the primary reason for the longer duration in clearing. My observation - the filter partly served the purpose & helped in circulating the water, this circulation in turn lodge fine particles into the substrate.
On day 7 - I opened canister & stuffed the vertical cavity in the center with finer sponge, than the existing one, & that’s when we noticed the water clearing out much faster. However, this drops the output of the filter by ~10% & is not recommended for proper functioning of the filter, especially when we wring the media using the external handle , hope you understand my perspective.
Second, the filter has two separate components – Pump(Aquamax) & Canister(Filtoclear). The pump has to be kept submerged in the main system which delivers water to the canister. The Pump housing does pre-filtration for debris size up to 8mm, which leaves a scope for small fish such as tetras, Ottos, etc. to get sucked in. We need to again cover this pump with yet another finer net / mesh to prevent this.
FILTOCLEAR & BIOPRESS SET are the sealed canisters, all other models are based on filter overflow method.
All in all, these filters may be good for ponds, but not for Aquariums that require viewing from the side. The canister models do not have layered media approach & options for alternate media. The pump pre-filter in not suitable for small fishes. There are other models – BIOPRESS SET that has space for optional media, but again it’s not layered, which I look at as a big drawback on both models.
2.5 times more expensive than Eheim, so I’d rather go for two Eheim’s that is meant for all glass aquariums & yet have all the available option required for a maintaining a healthy FW setup. With Eheim, I can still opt for alternate media & use it on a pond 
Having spent the money on an OASE, I'm now working on options to redo the setup minus the Canister to get effective filtration. Maybe, in aquarium partition with over flow or something.
