hi everyone, i have finally moved my fish to the 60 liter tank to free up my 8 gallon for the betta fish that ive always wanted, hooray!!!!!!!!!! ive got 1 in mind he is ab fab!!!!!!!! i have a HOB filter that does about 400 liters per hour but i have been told that betta dont like that much water current as it is fast for a small tank so my question is what is a good basic rule of thumb for the filtration needed ( im thinking of making a sponge filter) per gallon or liter, thanks for the help coz that all thats needed before i pick up my wonderful boy:hmm3grin2orange:

You could just slow the flow of your HOB, put a piece of fine pore sponge over the intake of the HOB. That should put some resistance on the motor and slow its flow down. You could also take a rubber band and attach a piece of large pore sponge to the HOBs return to slow and disperse its flow back into the tank as well as pack the filter itself full of media.

I think a sponge over the input tube should do the job.

If you have decorations or plants that can fit in there, the current will be dispersed a bit and the betta will be able to relax.

I had 2 filters running simultaneously: Top Fin 20 (30 gph) and a Marineland Biowheel (100 gph). The current was fairly strong, but my betta used the decorations and plants to rest.

Or you could always go with the sponge idea. :c5:

If you have an air pump, you can pick up a sponge filter for a couple bucks.
