Hob Filter For Cory Tank

Will be setting up a 20 gallon long tank to house 6 to 8 cories. The tank is only about 12 inches tall, so I'm a little confused about the 160 to 200 gph suggestion for HOBs, and the length of the intake tubes on these larger filters. Right now I'm looking at the Fluval C3, rated at 153 gallons gph, with an adjustable flow. Read in a review that the intake tube is 16 inches long. Would I cut the tube, go with the C2 or find something else?
Thank you!

 

You can cut the intake tube to the size u need. Ide go wit the larger filter.. I run a fluval206 an AC50 and a dual sponge filter on my 20 long

 

I'll get the C3 and add a sponge filter too. Thank you so much for your advice.

 

IMO unless the flow of the filter is affecting the inhabitants or the other parts of the tank in a negative way, no filter is to big ( within some reason)

 

The C2, C3, C4 was Fluval's attempt to make an improved new HOB, since the Aquaclear had already been out for a long time.

I still think the Aquaclear is more versatile than the C-series HOB's.

An Aquaclear 50 + a sponge filter in the other corner would work great.

 

I don't think the C3 will work for you if it has a minimum intake length of 16 inches in a 12 inch tank (depending on where the start of the measurement is). If the measurement starts 4 inches higher than the edge of the tank it should be fine, but if not there isn't really a way to cut the tube to make it shorter. There are little clips on the piece that goes into the filter that hold onto the "extension" part of the intake. If you were to cut the main part you would lose those "clips" and the intake tube wouldn't work as designed, also it wouldn't be usable for any larger tank in the future. Cutting the extension would do absolutely nothing for you as it already has a minimum.

 

Thank you very much for that info. I'll stay away from that one then.

 

I would go with the new gold standard of HOBs, the Seachem Tidal filters. The Tidal 55 would be perfect.

Suggest Seachem Tidal Filters for just some of the following advantages: Self priming w/submerged pump so it’s quiet and will always start after a power failure or maintenance, removable no spill media basket for easy cleaning and locks in place and won’t push up flooding your floor, variable flow control from 20-100% in 10% increments, built in skimmer, self cleaning impeller and comes with the best bio media, Seachem Matrix for nitrate reduction.

I was looking at those online. My 20 long is just 12 3/4 inches tall. Plus I have to subtract from that for substrate. Would you happen to know the total length of the filter with the intake tube?

 

Looks like the tidal 55 would work for your depth of tank

Look at the measurements for O

Just wanted to thank all of you for your help. I visited a semI local small aquarium shop this weekend. They had a tidal 55 in stock. Even unboxed it and measured the intake for me. It's going to work for sure. Love supporting any local non big box store, so I went ahead and purchased it. Thank you all again very much.

 

I think you'll be happy with the Tidal. I really like mine. I have a 35 and 110 currently, and soon will have a 75.
