Fluval 105 V Fluval 106

[Sharpy1987]

Hi guys,

Im wanting to switch from an internal filter to an external one.

I have a Fluval Roma 90 with a U2 filter at the moment.

I have been looking at getting the Fluval 105 external filter which is roughly priced around £57, however, i've since found the Fluval 106 for £68.

Whats the difference? which one would you recommend?

cheers

I know the 106 is the updated version of the 105, but what the difference is I can't say.

I personally have a 205, and I can't see what they could possibly improve upon in the 206.

What size tank do you have?

although the fluval 105 filter says up to 100 litres, is it better practice to get the one higher? ie. fluval 205?

will this benefit my tank more or cause my fish stress with a faster flow in a small tank? (90 litres)

i have guppies and different variaties of tetras but wanting cichlids eventually

I've currently got a 60 litre tank, but I went with the 205 as I'm hoping to get a bigger tank some time this year and didn't want to have to buy a new filter when that happens. The fluval filters are adjustable so you can turn the flow down if you feel it's too much. Personally I picked up a 19mm T pipe from my LFS which fit into the outflow perfectly and creates a soft flow around my whole tank (at the top level at least) rather than a strong flow in one direction.

From what I can see the 106 is rated at 550 lph, but due to the way they test flow in filters it's best to halve it to get a realistic reading, so 275 lph. Ideally you want at least 5 times the tank volume in turnover an hour, though if you have live plants some people will tell you ten. If you can afford the 205 or the 206, I say go for it. You can always turn the flow down if you feel it's too much, and if you ever consider getting a bigger tank in the future, you may not have to get a new filter with it (depending on how big an upgrade you make).

Thank you, you have been very helpful! I will go for the 205. However, do you happen to know the answer to the difference between the 205 and 206?

I'm also looking at buying 1 of these filters and wanted a bit of advise. The gap in the back of my lid is 1.5 inch would the tubes and fixings fit please? thanks

I have a few platys and 3 porkchop rasboras, and they are doing fine in a 15 gal. tank w/ 106. Hope that helps.
