Using Superfish HOB without the basket?

I have the Superfish HOB 50 on my nano tank and wondered if anyone had removed the filter basket case thing and filled the unit with media and sponges?
I want to give it a go but can’t figure out how I would do so and still have the water flowing through it correctly. It has the rubber pipe that goes from the pump to the basket and I don’t know if it would be best to remove that or not?
 
Hi all,

Normally <"I would just do that">, but I can see it is a bit different with the design of the Superfish HOB filters <"Superfish Hang on Filter 50 - Hang-on Back Aquarium Filter">.

I'd probably recommend putting a pre-filter sponge on the intake and then keeping the basket arrangement, but adding your own sponge. Edit: I've just found something useful from <"the pondguru"> (from about 9:30).



If the basket arrangement is now sealed <"Superfish Hang on Filter Cartridges (2-Pack)">?

I think you have three options:
  • Carry on buying the replacement units
  • Take them off and just have a larger prefilter sponge. You can chuck what you like in the resulting space, but it may not work efficiently if not all the filter media is fully oxygenated.
  • Throw the whole HOB away and buy a new one, one where you aren't forced to buy consumables.
It is option two for me, and after that option three.

Thanks Darrel. Yeah I was thinking option 2 from your list too, and see if the water flows over all the media. I saw his video and it seemed a bit extreme. The baskets you linked to aren't sealed, they pop open. I have some foam and bio media in th basket in mine and the water goes through it and then surrounds it, was thinking all the water flowing round the outside of it seemed a bit of a waster as it could be filled with media.

That would be my favoured option.

Perfect, I'd probably keep the carbon sponge (it won't be "activated", but it is fine for mechanical/ biological filtration) and throw the floss away.

You would need quite a big tank to hide that filter arrangement. Personally I had to turn him off as soon as he started talking about Biohome.......

That honestly sounds fine, you will definitely have <"enough physical space"> for nitrification to occur and <"oxygen is much, much more important">.

If you wanted to maximise biological filtration in the basket? I'd go down the <"floating cell media"> route.

Thanks again. I'll have a play around with it tomorrow. And yes the Biohome push in all his vids gets a bit too much.
 
I have the same filter on my nano. I discarded the activated carbon sponge and filled the top two thirds of the space with regular course sponge with some matrix in the third below . Have kept the fine sponge pads on either side which keep everything in place. Not sure how effective it all is but the resulting water quality is fine. As its just a shrimp tank the load is modest. (BTW I have also put coarse sponge over the intake).

Hi all,
Darrel links to the Pond Guru??!!!
I'll be honest, I don't actually have a problem with a lot of things that he says, and he does <"have a product to sell">.

I know that people like (and trust) him, and I think that is because he combines,
I did suggest to him (via email) that he might like to rewrite:
...... Do not worry about plant growth being affected in a tank which reads zero nitrates - the nitrate is processed into soluble nitrogen which is easily used by plants, boosting their growth.
Because it is <"scientifically illiterate">, and if the <"denitrification arc"> was <"converting nitrate (NO3-)"> to <"N2 gas"> it would have the reverse effect, but he didn't reply and it is still on the web-site today (12-06-2024) - <"Biohome Media">.

In terms of that product, if you ignore the cost etc., it probably works quite well, but <"not for the reasons he says"> - <"7.5. Denitrifying Media, Biohome and De*Nitrate in the Aquarium">.

Hi all,
your a legend round
Thank you, that is a <"lot more complementary"> than a lot of things <"I've been called">.

For me, the issue is that we live in a <"post-truth world">, and it is really <"difficult to differentiate"> the truth from the lies. In the case of the PondGuru I have no idea whether he actually believes what he says. In the case of <"Seachem? I'm pretty sure they don't">, because they write their advertising <"very carefully"> to avoid outright lies.

One problem that scientists (and knowledgeable people generally) have is that they tend to use language and couch things in terms that leave space for some doubt, that is why it is the <"theory of evolution"> etc.

As an example I was asked the other day where "Global warming (climate change) had gone?" I pointed the questioner to <"Climate stripes - University of Reading"> and they said "well he obviously doesn't know what he is talking about, it is f*cking freezing", and I told them that you can both be right and that our cold weather doesn't preclude global warming, it is 40oC in Greece / the SW USA etc, but they preferred to belief <"their personal experience">, mainly because it reinforces their <"confirmation bias">.

<"People like certainty"> and, in areas where we don't have much expertise, we are more willing to belief some-one who doesn't <"have a scintilla of doubt">.
