HOB Filter

[Pittsburgh88]

How many people run a HOB filter for a reef tank? I have one running that all it has is a bag of active carbon in it? Should I let this run 24/7? I also run filter floss in it and I usually change that about 1x week just curious to everyone elses routines.

I have run several tanks with HOB filters. I just run carbon and floss as well. No problem running it 24/7.

How often you change the floss? I just do weekly changes.

 

[saltyfilmfolks]

I change mine monthly.

I typically do once a week. It really depends on how fast it clogs and if nutrients are an issue in your tank. BRS did a study that showed filter socks are most effective at removing nutrients if changed every 3-4 days.

I usually change mine weekly or depending on how it looks to be honest.

I have a 30 gallon tank with a HOB. Runs fine, only have carbon and polyfill.

Mine is sumpless.
In my sumped tank 3-4 days is as long as. Sock lasts

As long as you have enough rock for biological filtration then you should be good.

You can even add a sponge filter to the intake, this will drastically cut down on the floss needed.

What type of filter is it?

Seachem Tidal Filter.

On my non AIO tank I run oversized aquaclear filter modded into a fuge. I can run carbon, and I do floss and chaeto and rubble.

Seachem Tidal Filter.

That's a pretty good filter.

I would get a sponge for the intake, double the foam insider, and either pack it with matrix or similar media, and then floss on top.

How big is the tank? Probably don't need carbon if you're keeping a good water change schedule.

75 gallon and I do weekly 10 gallon water changes.

I would only use carbon as needed. But that's just me, and there's more than one way to make a filter for a reef.
