Good value under gravel filter.Nicel
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.

Does the job
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

Puts air into the water
Simple to assemble just cut out a few joints Puts air into the water - fish need the oxygen to live Just 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 fish Put 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 fish I have ordered another set as I’m expanding my tanks again Very good product

Best filtration system for aquariums
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.
