The pet store may not tell you this if its the pet store i think it is. Don't replace the biomax! Don't rinse it under tap water!
There is a chain of pet stores in my area that are also in newfoundland that sold my buddy biomax (a new pack every month for several Aqua Clears) for about 6 months. He was advised by them to replace it monthly

I also don't use carbon (expensive waste in my mind, unless you are removing meds), but that is a personally choice. I personally would replace the carbon with more biomax.
It says on the box to replace it every 3 months. I already know that is BS. I asked my ex's dad. He keeps 1,000$ sting rays, many different species, african cichlids, arowanas, and an asian looking cat fish

He told me that biomax never goes bad.
And I kno not to replace all my media at the same time, and not to clean it with tap water. I will rinse the sponge out, and maybe the carbon, with the tank water I siphoned out.

You don't need carbon in the filter. I would reserve those for after you treat with medications.
I've never had to replace a sponge, could you return those for your money back?
Well I have carbon in it right now to obsorb water impurities.
Doesn't it also cut back an any tank odor?
And as for the sponge. those were like 3$ for the 3 pack. Very cheap.
And I can use one to clean the algae off the inside of the tank.
This is to all.*******************
Is it mating season for goldfish?
My small goldfish has a white is bump coming out of its reproductive area.
I looked on the gab site and that should be the females convex.
It releases a chemical that make the male nudge the female in that area with his head. correct?
The other goldfish doesn't have that any convex sticking out, however I cannot see something like a hole there that the males should have.
The believed "male" is nudging the believed "female" in her private area, and following her around.
