I have two Fluval 307’s on my 75 gallon tank. Why? Well, for starters I like redundancy. I also wanted to experiment with different filter media – one of the filters uses mostly chemical and mechanical media with foam pads and activated charcoal plus resin mixes i.e. Chemi-Pure, Fluval Clearmax Phosphate Remover and Purigen. The other filter also has foam pads, but I put in more biological filter media like Seachem Matrix and Marineland Ceramic Filter Rings. As you can see I like to use a mix of products. 🙂
As far as the filters go they are very well designed. I hadn’t had a canister in several years and this one is definitely a step up. Once it is set up the media is easily replaced without having to disconnect the hoses. The units have 3 trays to allow use of various filtering media as well as internal sponge filters to reduce particulate accumulation on the tray media. The canister’s head and seal are all easily opened and closed. The unit is quiet and uses very little electricity (about 15 watts for the 307) which meant I was able to use hook each one up to some old UPS battery backup units I had and have the filters keep running when we had a power outage.
The hoses are not the typical ones. These are ‘ribbed’ and accordion-like is the best way to describe it. They work well and the only gripes I’ve heard are from people trying to connect them to other items like inline heaters and UV sterilizers that have standard tubing. It can be done, you just have to sort out the measurements. Fluval has a new inline UVC clarifier of their own now but I haven’t tried it yet.
I set the filters up in an overlapping pattern and adjusted the nozzle directions to try to get the water flowing all over the tank and avoid dead spots.
The final result is a healthy tank that is forgiving of my occasional overly generous feedings.
I am very pleased with how well the Fluval 307 filters perform and the design excellence. If I ever manage to get some additional aquariums I plan to try out their other models and series.
As a final note let me say I am not independently wealthy. This equipment was purchased in stages over a year and I used some gift cards and reward points I’d accumulated. I also was fortunate enough to trade some tools I wasn’t using with a guy I met at a SCAPE club meeting which meant I didn’t have to pay for the aquarium, stand or gravel.
Since I am on the subject a quick plug for the SCAPE (Southern California Aquatic Plant Enthusiast) club. If you are in the area they have regular meets with auctions and trading. If you attend a meeting you can request a membership card as they have negotiated discounts with some local fish stores. The online forum has a Tradewinds subforum where people will seek to buy, sell, trade and even give away items; members will sometimes team up to negotiate group buys. The members actively trade and breed a wide variety of fish, plants and live foods. You can find them on the SCAPE Forum and their Facebook Group page. There is an unofficial Discord channel created by some members though it isn’t as active as the other two options.
