i stand corrected. glad to hear you had good experiences with them
if everyhting is 0, that is another reason taht you are probably going through another cycle. get some media from another tank if you can.
i was going to swap filter bags with another tank but people in chat told me that would just screw up the other tank
i have an idea....
you know those little black "bio-filter" sponge things in front of the filter bag... i will swap those out with my other tanks
sound good?
