I bought a fluval canister filter, it was kind of just an impulse buy. I'm scared to use it though. Now you may be wondering why, well, it isn't the replacement of parts or even the maintenance of the filter. Before I got the filter I made sure to do my research but there's a common issue I kept stumbling upon. Leaking. I read pages and pages and pages of people talking about fluval filters and in general canister filters leaking from various areas. Wether it was from a part in the cord, from the area where the o-ring lies or wether it was within the canister area itself. I understand that canisters have many benefits, one of them being the advanced filtration they provide. From what I read though, these leaks have caused stands to be tarnished, carpets to be drenched and floors that have become ruined. The tank that I was planning on to use is going to be placed in hardwood. If a leak occurs it will ruin my hardwood flooring. So to avoid this, I was going to place the canister in a bucket so if it leaks the bucket collects the water. Another issue is, what if I am not at home and the filter leaks rapidly and surpasses the buckets capacity causing the water the overflow on the floor. That also means I would loose water within the tank harming my fish and possibly killing them. I'm not always home so I can't keep a super close eye on the leaks. Aside from that I also read issues about canisters being loud and making a groggy noise when air is trapped. The last thing that I read was to keep canisters running you will run in to times where you have to replace parts. For example it is recommended to replace the o ring yearly. For me, I looked at the prices for replacement parts and they were very expensive. Parts like the impeller. I also read about many fluvals that had priming issues. All of these things have kind of discouraged me to use the canister filter. I was thinking of refunding the filter and getting an aqua clear instead. A lot of people say between HOB filters and canister filters it is personal preference. As I said, I won't always be home and I want to make sure my fish are always healthy and fine even if I am not at home. There aren't a lot of issues that arise with HOB filters and they're relatively cheap. My second last question is if a HOB filter powers 120 gph and a canister filter also powers 120 mph why is the canister better? To end off finally (l0l) I'm torn on wether I should keep my canister or switch it out for a hob. Should I keep the canister/ why should I keep it or should I switch it out? Maybe I shouldn't have read those pages about leaks lol. Lastly if you have made it to the end of this, thanks for reading all of this.
