Thank you. I have had my canister going for 2 years but I also have two HOBs and 3 sponge filters due to my water not being right most of the time so I keep adding different filters. I may have too much filtration, I don’t know. I also have a lot of plants. My guppies have never done well in this tank. I have other aquariums that only have a Hob and 1 sponge  they are always good. With platies and mollies in them. I have one bare bottom with a mix of fish 10 gallon for grow out all is well with it. I think I will take off the canister and slow down the filtration and see if it help.

I already have one in my 75 gallon it’s the fluval also just heard from other people that they are not good with no reason for it. My guppies keep dieing off and the other tanks I have are all kept the same way just don’t have the canister filter so I thought maybe it could be why. Just wondering?
