Sump Pump #1
Bit of a rhyming title going on there

I've been thinking about buying a 6ft tank for a while now, i've finally found somewhere that seems quite reputable and doesn't have prices that are going to bankrupt me.

The tank im looking at should hold approx. 450-475L by the time i've got all my bits and bobs in. It will have a glass sump for filtration (not sure of the size at this time)

My question is how many litres an hour should the pump i'm looking at buying for the sump be shifting? The lower end ones are doing 1000-2000 l/h while some are upto 5000 l/h.

I'm sure i've read somewhere it should be doing three or four times the tank capacity if possible, but I can't find where I saw this info, so any help would be great :)

Re: Sump Pump #2
Is this marine or freshwater?
For a marine tank I'd be aiming for about 10x capacity as the flow rate needs to be kept high. For a freshwater traditional enclosed filters capable for that size tank would run at about 1500lph but I'd go a little higher than this and suggest 3000lph. Don't forget to take into account the pump 'head'.

Re: Sump Pump #3
It's going to be a freshwater tank (clown loaches needing a bit more fin room)

The lady I spoke to at the company suggested the Ehiem Compact +5000. I'm guessing this is considering the water in the sump tank as well?(sump will be 48x15x18")

Despite reading about 2 million articles on sumps im still slightly clueless xD

Re: Sump Pump #4
The compact 5000 is probably a good choice. Although you get 5000lph on the level by the time its pumped up a meter into the top tank the flow is less. Probably about 3000.
You can always turn it down if its too powerful. Will you be ok with the noise? They're quiet for pumps of that power, but not silent.

Re: Sump Pump #5
Excellent, thanks for the input!

I'm not too worried by the noise, the tank wont be located anywhere that's used too much, if it is too noisy im sure i'll think of something.
