I want to use a Seachem 35 filter on a 20 gallon high, is there something called over filtering?
is it bad or good though? I didn't say a 75-gallon filter, I said a 35FishBoy101 said:Yes, there is such thing is as over filtering, but you don't have over filtering. I'm planning on adding some more filters to go with my 75 gallon's filter. A 35 gallon's filter won't have much of an affect on a 20 gallon.
I voted yes because a 75 gallon filter on a 20 gallon isn't the best choice of filtration I feel.
Im planning to add 1 betta, 6 panda corydoras, and 8 neon tetras or 6 dwarf red coral platyor 9 ember tetras. Is that enough "food"?Mudminnow said:Although it may seem like it, I don't think FishBoy101 and I are in disagreement here. I think it has to do with what type of filtration we are talking about.
In my response, I was focusing on biological filtration. I don't think it's possible to overdue that, because beneficial bacteria colonies can only grow as large as the food available to them...no matter how big the filter.
If we are talking about chemical filtration, I could see how one could over filter. DI water for example is too clean on its own and will stress fish.
There are other things filters do besides just filter too. They provide flow. If your filter is providing too much flow for the inhabitants of the tank, then it could be said to be over filtered.
The more biological filtration the more bacteria.Mudminnow said:Not to my knowledge, no. If your filter is bigger than you need, the beneficial bacteria colony in it just won't grow as big as it could have. I personally like to run oversized filters, just in case my bacteria colony would need to grow larger to handle more waste for some reason.
