my boy and i had a debate about the hobby today can you guys help. here it goes -- i have a 180 with a few fronts dats and sevs all about 3-5 inches-- my filtration is 2 fx-5 and 1 xp4 hooked up to a supersized uv sterilizer. in the xp4 i have lava rock and i clean that once a year--one fx5 i have nothing but carbon that i change every 2 months and in the other fx5 i have it stuffed with scrubbies that i clean every 3 months religiously when i clean the fx5 with the scrubbies i "rinse" the gunk and goo off inside the filter water then i dump the dirty water rinse out the fx5 then i fill the fx5 with water siphoned out of from the tank---my boy believes that im killing off the good bacteria because the scrubbies are exposed to the air which isn't good according to him---i say because i rinse the scrubbies in the old water and fill up the fx5 with aquarium water my bacteria is not affected ---my fish are happy and healthy water is crystal clear like the fish are suspended in mid-air----WHO IS RIGHT ON THIS ONE THERE'S A CASE OF BEER ON THE LINE LOL
