Koi are not the easiest fish in the world to keep. I would suggest (as you mentioned) That you learn to keep "ordinary" fish before you have koi. Then you will know exactly what you want and how to do it.

.....does the flow-rate of the filter refer to the amount of water it can handle from the pump, before it floods?


No.(Not quite) its to do with how much "processing" the filter can do. Too fast and it will not work properly, Stupidly fast and yes it will overflow.

Yes and no.

There is a whole host of things you could learn about pumps, but you don't need to know most just yet. For the time being lets say "get one as close as you can to the filter flow rate. (You can always turn a big pump down, you can't turn a small pump up.)
Good quality costs. Bear this in mind before you start.

Re: Help! My pond fish keep dying. #33
Thanks to everyone for all the info, things are starting to make (a little bit of) sense now! Ianbo, I couldn't find the filter on ebay, it might have sold by now, Wakefield isn't too far away so it would have been handy. I would appreciate some details about the Fishmate kit so I can weigh up all my options. Also, what do you know about the Yamitsu mega black box filters? Are they any good/suitable for my needs?
2010, from your comments I take it the ideal thing is to get a pump which has a max flow-rate a bit higher than my needs, but with the capability to be turned down? (I know you said that the Oase Aquamax, for example, are not adjustable).

Re: Help! My pond fish keep dying. #34
the fishmate pressurised containers are a completely different type of filter.They must not be confused with box filters.Fishmate sell the filter and pump as a kit yours is 15000 ps with a maximum fiow through of 7500 l/per hour.The correct pump is a fishmate 9000 l/per hour. seems excessive i know. I have rang fishmate for info in the past.They informed me that you will lose 10% by pumping 1 mtr to the filter this will reduce flow to 8000.Because the unit is pressurised the amount exiting the filer will be half reducing flow to 4000.This means you are at circulation of twice per hour.The pump has an adjustable flow which will allow you to reduce it further if you want.At no time should you be getting bad filteration because you have not exceeded the maximum flow of 7500 l/per hour

The cheapest price for this pump is ?143. The downside is that it is not a true solids handling pump,it is advised by fishmate to reach solids handeling of 6mm that you cut some of the ribbing on the cage away.This area is only about 1/8 of a solids pump.Imagine the pumps 2010 showed you, the central section of the water feature pump only is removed.The pump will be ok but is not like the solids one.

Circulating the water more should not cause great problems. It you are unsure ring fishmate helpline on 01932700000 they are quite helpful.

It leaves you with the decision, do you spend more on the other set, i suggested it does work a lot better.

Re: Help! My pond fish keep dying. #35
The filter on ebay did not sell but after looking again it was well used and was a little different to mine, I have saved some info if you want it
A friend of mine has the black box mega filter and really rates it. They are a bit cumbersome and are made out of plastic.But with some planting they can be softened into yur garden.Some have built in uv.Be sure to check specifications out because some have a min flow through as well as a max.These filters are normally sold by specialist pond suppliers so I think you are now looking at better filters

The filter I suggested are similar to the one 2010 showed you but are smaller, the 4000 is 3 ft in length and the 2500 about 18 inch square and both made out of fibergass. these filters are a bit better made and come in green but they cost more.

when you got your last set up under way did you stop feeding.if not this can be a problem as it takes time for the bacteria to establish

The filters you are looking at will allow you to keep larger stocks,probably twice the 107 cm you mentioned before

Re: Help! My pond fish keep dying. #36
If you are thinking of the kockney koi black box range the mega mk II seems a good choice . It is capable of filtering a koi pond of 4500 liters. It has an 11 Watt uv which should be fine as it is long and the water has longer to pass thrugh it. The minimum flow rate is 500 gal which is 2275 liter per hour. This means that if you put koi in your pond which you intend to then the total volume of your pond will be only slightly over the recomended once per hour.I know some people who circulate their water more than this with no adverse effects.I think this will give you realy good filteration

The next step up is the multibay type box filter which gradually filter through each chamber

Maybee wait for 2010 to give his thoughts on this filter

good luck

Re: Help! My pond fish keep dying. #37
The black box filter I mentioned stood out to me because it is the smallest one with a built in uv.It would cost ?50 to buy that uv as a separate and it is neater when fitted to the filter.You could get a smaller filter box if you wanted but that would mean an extra cut in the pipework to fit an inline uv and you would have less filer capacity for about the same price. If you bought that filter it may be an idea to connect your neptune pump to the filter then measure the water flow output then you can gauge the size of your new pump.The only addition you may want is to put a fitting to the drain plug on the bottom of the filter to make it easier to drain sediment, these cost about ?15

Re: Help! My pond fish keep dying. #38
[To no one in particular]

First of all, I no longer like to recommend a specific product as it may be "just not the one for you"
If person Q likes a specific brand it does not mean that person R must have it, there are still other brands available.

I will also like to point out that the filter on ebay was listed as a gravity fed filter. Bluechild's set up is going to be pump fed. The makers of the filter offered on ebay make two versions, one is for pump fed systems the other is for gravity fed systems. You can not easily change your set up from one to the other.

Well since you asked.

Lets us look at this filter:

Name Mega Mk2
UV Size 11 Watt
Pond size (Goldfish)1,700 Gallons
Pond size (Koi)1,000 Gallons
Suggested pump ssp 4,000
Max flow 900 GPH
Min flow 500 GPH

All info taken from This page


Other information:

Dimension of pond 8 feet long, 3 feet wide, 3 feet deep.
Volume (if filled to the brim) 448 gallons

From the above is is easy to see that the filter is over 4 times as big as the pond requires.
_____________________________

I also feel I should mention the following:

1)

The guarantee will now be void, (You damaged it) and you may also allow more damage by letting in particles of a size it is not designed for. You should NEVER alter / change any pump. You can of course add accessories that are designed to fit.

2)

Bluechild is "starting again" after losing all the previous fish, KOI are NOT a beginners fish, and you can not, at a later date "Throw in some koi, as they will only grow to the size of the pond"

By their very nature, Koi need great dedication and a much bigger pond etc than is currently available. Please stop mentioning adding koi.

Re: Help! My pond fish keep dying. #39
as I said I have a fishmate pump and the instructions this is the advice from the manufacture. I am in not in any way trying to advise bluechild to intreduce koi at present but to try and have an a filer that will cope if he does.

That's not the way most of your posts read, but let us not argue over it. The fact is you are also over looking the obvious. The pond is too small for koi. Click me
