Long story short im going canoeing and i was making sure everything was in working order. My luck would be that 3 hours before i leave, my 1 month old filter stopped working!!!! Its top fin brand that supposedly has lifetime replacement but i don't have time for this now. So i drove 20 miles to my closest store and the employee was new so not much help. I ended up grabbing a fluval 30 that cycles 150 gph (i have 30 gallon tank) Its quiet! It works! It looks super fancy yet simple. Comes with carbon and biomax and a sponge. So all 3 filtration in 1 (so was the top fin but that didn't last long). Now my question is...... How do i do this so i don't lose my cycle?? Please i just finally got cycled last week since i did fish in cycle. No casualties (thankfully) I did order a 2nd filter prior to have extra filtration because my mollies are dirty. Poop machines!! But its shipping from Hong Kong and wont be here till july 22.
