My filter which was a top fin silentstream 20 gallon broke all together . I went out first thing and bought a Tetra Whisper IQ . They didn’t have another top fin in stock and I was desperate . I don’t want my cycle to crash .... I put the cartridge from the top fin into the tetra along with the new cartridge that goes with the new filter . Will this be ok ? It took me so long to get the tank to cycle !
