I only use sponges and floss for my filtering media, and when I clean them I often just give a good rinse in the sink. The tiny amount of chlorine it is exposed to for a few seconds is not going to destroy the beneficial bacteria.
got a 320 gallon tank full of big american cichlids, it was filtered with nothing but 4 sponge filters for 2 years. It was perfect lol. I added an fx6 just recently not because I was having problems, but to polish the water and make it crystal clear (purely aesthetic reasons). Fitlering is way too overrated lol, i realized that if my tank, with that amount of biomass, was fine with just 4 sponge filters, any tank can be ok as long as you keep up with water changes and cleaning
I doubt any of those way fair tanks are in stock. They probably make them as they get orders for them. Then it will take three months to get it or longer.
