20g Crystal Red Shrimp tank Question

Wasn't sure if I should ask this on the equipment board, or here, so I've posted it on both.

I am currently in the process of setting up a 20g CRS breeding tank, and was wondering what type of filtration method would be most recommended? I have the opportunity to purchase a used eheim 2215 at a great price (30) or a used fluval 304.

What is the best option?

I think air driven sponge filters are probably the best bet for shrimp breeding tanks. Bio load is usually low in shrimp only tanks so the sponges are more than adequate. HOB and canister filters will work but I prefer to save my money on those items and instead purchase more shrimp. If you decide to use an external filter, you should invest in some sort of covering for the inlet of the filter to keep small shrimp from being sucked into the filter.

At that price, I would still get the Ehiem and save it for use on another tank.
