So a 75 gallon tank was given to me! I'm pretty pumped and all I need is a better filter, or more filter to get it going! I currently have a 30 gallon with a whisper 20 at 110 gph, and a top fin 30 at 145 gph running side by side. I found what I think is a great deal on another filter (please correct me if it is not) for 30 bucks. It's a marineland C-160 canister rated at 160 gph. Here's my main questions. Can I fishless cycle running only the C160 on the 75 gallon? Then also, once the cycle is complete, running the three filters together on the 75... Would I have adequate filtration? Thank you for the insight!
