What is the smallest pump I could get away with?

[Brent Shaver]

As mentioned before I have a 40 gallon tank that I am going to use to house the new fish for my planted tank.  I will not be using this other then for a hospital tank or to keep these fish until the other tank is ready so I dont want to spend huge money on a canister pump and I tend to like to go new vs getting one used.

Is there a HOB that would do the job and work well enough to house 40 small fish?

Brent,

An Aquaclear 70 HOB will do the job for you.  I am using them right now on each of my 40G breeder tanks.

Exellent, thanks...  I had looked at them but wasnt sure if it would be sufficent for that many fish.

Thanks again
Brent

Sponges filter with air lifter tend to be an inexpensive, yet very excellent solutions for bio-filtration.

For sure these a great units I swear by the Aqua Clears. I had them in almost aof 16 tanks I had setup. Either as primary or a secondary filter on large tanks over 38g. Sponge filters are cheap and offer large bio-filter area but do little for water flow.

Better yet Brent, why not do both if possible?  Each of the filters does offer its own advantages. 

An even better idea, why not try out the HMF that Udo did a presentation on at our last meeting?  The HMF offers both very good biological and water movement.

I am doing the hamburg with my planted tank in a sump.  This is just a quick and easy slap together to keep the fish healthy until the tank is ready.  I can cycle the pump in no time on my 110

It will also be a barebottom so my python and waterchanges should be more then enough for a couple months

With a bare bottom I agree with Fishbuddy you should do both. Thing about a substrate if it's vacuumed it is also part of your bio-filter.
