🔵 EHEIM Substrat Pro 1L - Advanced Sintered Pearl-Shaped Glass Bioballs for Biological Filter Media Review

Reinstalled my aquarium. I now have a Hydor canister filter but this medium seems to handle it well too. Tank is balanced.

It's like putting a turbocharger on a tank. After installation, you essentially add a water crack to the water column. I can only warmly recommend this German development.

There is simply no comparable biocarrier. The price was very good too. Cheaper than the crap from your LFS or pet supply chain inventory and 2000% better. Buy it.

These media are great, my water chemistry has always been stable since I've been using them, can't complain, they will probably last my fish tank for a lifetime, they don't fall apart, will buy again in the future if it is a must and definitely highly recommended

I have used this in two different canisters and also to fill a submersible filter on my used Fluval Accent rig. It seems to be working great.

I recommend using a mesh bag or two to hold the load and make flushing easier. The Substrate Pro is a bit small and light, making it easy to slip away from you

This works very well, although every time I've cleaned the filter I've noticed that the small beads have fallen apart a bit and there have always been small pieces at the bottom of my filter. This has never been an excessive amount so I'm fine with that as long as the fine filter pads can continue to keep particles out of the impeller. Additionally, my 55-gallon freshwater stays stable thanks to a

I have just installed a new tank and am using it for the first time in a hanging canister as a biofilter. I love it. It has a texture that should encourage bacterial growth - one of the best I've seen. Being completely round and porous, they should have maximum contact and growth with water. There are no fish in the tank and the ammonia digestion has really skyrocketed: the tank is consuming a total of 4 parts per million of dissolved ammonium chloride per day and I attribute that to Eheim…
