Biomax vs Siporax vs Absorbex - Absorbtion & Capacity Test Review - HD
Biomax (by Fluval) vs Siporax (by Sera) vs Absorbex (by Hobby). I just tested the in my eyes 3 best types of filter media for absorbtion ability, which leads to the best housing for nitrobacter. The second part at 3:00 shows the weight in dry/wet condition + the gain in percent. The green fluid is water mixed with food colour. The third part will deal with the dimensions. A resume to all this and what it practically means, or which one is best under certain conditions will follow.. Your are welcome to comment on this.
