>> For the past few years I have used Penn-Plax Cascade 300s. These are a small but powerful, very easy to install and use internal filter. I have two for each tank and at $14.00 are a good deal.

My Magnum is great for the painted but if when we get a new tank for the mud I'll keep this Penn-Plax in mind in the event our ZooMed doesn't do the job anymore.

Today the dog has to see the vet. I put off calling her about ordering a 40g breeder for the mud because I knew I'd be there today. Hopefully this afternoon we can get that new tank on order.
