So when I took the under gravel plates up after years of use and barely found anything I was hallucinating? I test my water regularly I am not ignorant and I do not appreciate being called so by a moderator. What problem exactly am I not seeing ? My water parameters are perfect.
I also never said to run a UGF on its own that would be silly. I run a HOB and a canister and an under gravel filter. Also I have run under gravel filters on my tanks since I was 6 years old. Besides when the power goes out what are you going to do? I just battery power my air pumps and bam I got a bio filter running. Sponge filters are neat and have their place I am not going to argue that.
Not everyone can afford an eheim 2080 and a 2262 like you have. Your filtration would make an undergravel filter unnecessary however for john every man most will need added bio if they are on a budget.
Id like to see you argue with the owner of capitol aquariums my LFS all their tanks run sole under gravel filters and have for 30 years successfully as many people have as well.
PS Which HOB has more bio capacity than a under gravel filter on say a 55 gallon? AC110 ?? No I think not
Secondly I chose non coated gravel as many do when they pursue under gravel filtration so please tell me Whats this ignorant thing that I am missing with all my testing and 16 years of experience with under gravels ?
