Penn-Plax Undergravel Aquarium Filter for 10 Gallon Tanks – Two 9.5” x 9.5” Plates – Under Gravel System for Clear, Clean Water – Safe for Freshwater and Saltwater Tanks

It does the job very well

These old school gravel filters are by far the best for a healthy aquarium. I’ve used cartridge filters in the past and they can’t compete with gravel filters. Crystal clear water, balanced levels, plants growing well, happy fish and a lot less maintenance. The only thing you will need is monthly 25% water changes but that’s a must with any tank.

The only thing I can falt it on is the filter pipe that adjusted the hight was a bit loose fitting but a little ptf tape sorted it out

Filters great

Nicely made and works well as is usually the case with Penn-Plax products. It was delivered inside a strong, cardboard box and I am pleased about that.

The media could not be loaded. Simple to assemble just cut out a few jointsPuts air into the water - fish need the oxygen to liveJust using it to keep the little ones alive - had loads and loads of eggs laid in my Aquaponics but were slowly getting eaten by the bigger fishPut the weed containing the eggs into a medium container - revamped it using the filter and as you can see from the video I now have over 30 more fishI have ordered another set as I’m expanding my tanks againVery good product
