Can Over Filtration Defeat Bio Overload?

[AugNYC]

Hello new friends. After several years of maintaining larger fresh water tanks. I've decided to set up a SEPARATED 7g tank with my 2 favorites. A male betta & a male crayfish(again separated).I've installed a penquin 100 on each side.The tank was started
with gravel debis from an established 30g. Two questions... Is this a bio overload? & can overfiltration defeat bio overload?
Any opinions(not insults) are welcome. Augie nyc

Confused as to your interpretation of Bio overload. As for waste your not going to have a problem using a Penguin100 on each side as these are rated for 100gph . over filtration is not an issue. the resulting flow may be especially for the beta as they like calm water.,
More is better for filtration but you should take into account the preferences of the inhabitants.
What, if you could elaborate is your exact question again?? I'm feeling a bit murky here.

Your filters will only support enough bacteria to deal with the waste from the 2 inhabitants. The flow for the Betta, as mentioned is going to be an issue unless it is directed towards the glass or an object of some kind.

i've overstocked/overfiltered before and it was fine. so short answer to your question is yes. The good thing about having 2 filters is that you can clean one and leave one running, reducing the risk of re-cycling, however, thats a whole LOT of filtration for such a small tank. Even just one of those filters is probably twice what you need. The filters wont hold as much bacteria as they can as the waste wont be there from the fish to feed them, so its probably as well just to have one running imho.

Hello again/sorry I didn't check my replies sooner...The original problem that prompted me to reach out for opinions is the tank refuses to cycle & its' been like 6 months.(I bought a new water test kit when I set up the tank).I don't over feed & I only vacuum or change water when it's neccessary(I don't want to disrupt the cycle).As for the excessive current on the bettas' side,I only cycle his filter on for 15min 3x a day. He seems to enjoy the exercise.(it's like riding in a car with the top down).The odd thing is they don't SEEM to be bothered by the poor water quality(I've had bettas in a cycled tank that weren't as happy).

the filter off and on "15min 3x a day" it will never cycle.
A filter should be on 24/7 the bacteria need water flowing and oxygen, they can go short periods without but it wont work in the reverse.
