Eheim Substrat Pro 1 liter
This product serves it's purpose very well.
I have always been a fan of Ehiem products and filters. I have not found a filter system that performs better. I had stored my filters away since I didn't have an aquarium for several years. I recently put them back into service. I was delighted to discover Ehfisubstrat Pro. I find it to be far superior to the older sintered chips. I like the fact that this product can be rinsed and reused several times. To date, I have purchased 7 liters of Ehfisubstrat Pro. This way I can partially change the media while the dirty media is being cleaned. Note: don't change all of the media at once because you will lose the beneficial bacteria. I recommend this product to anyone who wants the best.

I would not recommend anything else!
Between my 3 tanks and all Eheim media, even in my Fluval canister filter, this stuff can get pricy. But, if you are like me then you do not mind paying for quality. I have never had to replace any Eheim Substrat Pro and is my #1 pick for the bio filter. Thank you DrsFosterSmith.com my planted tank thrives!
