Aquaclears and Whisper filters F/S

[jaa1456]

I have a brand new Aqauclear 300 no box. It is the older version of the 70. I aslo have a mini Aqauclear that is now the 20. It does 100 GPH. It is used. I also have a very large whisper 4. Looks to be easily 4 times the size of the aquaclear 300. And a whisper 10-20 or 40. There are two different tops and both fit the filter. Not sure which one it is. I want 25 for the 300, 15 for the mini and I want 15 for the other 2 combined.
