A local person has an Aqua Clear 70 for sale for $20 but it needs an impeller. Can I use an Aqua Clear 20 impeller in the 70 to lower the flow rate?
I'd like to put it on my 10g and I'm afraid the 70 with the stock impeller would be to strong. I was thinking with the 20 impeller the flow would be lower but I'd still have the big media basket for extra filtration.
