Sponge filter and pump?

I've never used this filter and it sounds pretty good for shrimp tank and very cheap as well. What pump do you use with this, and can you adjust the flow either on filter itself or pump? thanks

I don't know of any sponge filter you can adjust the flow on. They usually a very simple design.

I adjust flow by using air valves - you can either partially close it and put back pressure on the pump or if you use one that has several valves ganged together you can open another one up a little bit. These are really cheap.

Hi Hunter, I put a couple of these in my shrimp tank. I bought from eBay which has a guy in the Midwest that sells like 4 double sponges for ~$10. That store also has air pumps that you buy. I'm sure there are quieter air pumps out there, but it was convenient to get 4 sponges, air pump, air tube and check valves all in one place. I think it was $25 total.

I found these filters very cheap and seems very efficient. I think what I need to look for is adjustable air pump to control the flow, not the filter itself. Yeah I'll check out eBay for a good deal.

They also have control valves that can help to control the flow. It looks like a plastic needle valve for air

I run two of them. One a regular hydro sponge pro, another a dual sponge. They are great for keeping the water clear and hold so much biofiltration. I run both on regular air pumps. You can do this, or run them on powerheads.
I do suggest that you rinse them well in tank water every month or so. I figured out the hard way that if you dont, your nitrates will go sky high.

When you mean adjust the air flow, do you mean you want one specific pump you can constantly change the rate of flow or do you want a pump that will pump air above average speed?

Yeah I could use control valves or this pump, you can dial it down.
