Should I buy a new filter?
My betta died some days ago because I brought 5 neon tetras from Petco.
I do not know if he died from stress / exhaustion (he was chasing those neons like there is no tomorrow) or if he died of some deadly bacteria I brought with the neons, but I want to start the tank from scratch.
I did not throw anything away but I washed them very well.
My only concern is water filter. It has 2 filters: one glued to the filter, the other a sponge that can be taken out.
Is there any chance for the deadly bacteria to survive in the glued filter?
Now I am drying everything and I plan to start cycling the tank in 2 weeks from now on - to be sure that nothing is alive. But, would drying all the stuff inside be enough?
Thank you for your help.
