Juwel Filter Sponge Order

[firsttimefishboy]

Hi, new fishkeeper. 96ltr Juwel tank is now cycling. I have put the sponges in order in the filter according to juwel.
They say the fine should be on the bottom and the coarse half way up but that seems to go against what i've read about filter sponges on this forum. Shouldn't the coarse sponges be at the bottom to catch all the larger debris?
Any advice helpful.
Thanks.

I'm also a beginner, but on my RIO 125 the coarse sponges are on the bottom with the white poly pad right at the very top. There are two plastic filter containers in mine.
From memory the one on the bottom houses a blue and green sponge. The top houses the BIO mech stuff, one blue, 1 black (carbon) then the white fine poly pad.

Hope this helps

Thanks, that makes a bit more sense as I thought all the crud got dragged through the vents at the bottom.

It's good to know for sure the exact path and flow direction of the water inside your filter, then you can better understand what you filter designer had in mind and decide if you want to second guess it with your own stack. A very popular design is to have the intake put the water at the bottom of the filter box in an open water area (which allows really big sediment and debris to be free to collect) and then have the water go upward and hit the most coarse media, which might be large ceramic rings or a very coarse sponge. Larger debris then gets trapped and the water flow slows down and small streams of movement are randomized across the media volume. Next comes the true biomedia, which is usually also a medium-sized debris trap (sponge, ceramic gravel etc.) and finally the fine mechanical media, usually a polyfloss pad or bed or some sort of multi-density sheet.

I'm a beginner too, but in my vision 180, Bioflow filter, it has an inlet grille at the water level front, which lets water *down* through the filter, so my media goes poly pad at top with two coarse filters underneath (top basket). The bottom basket has the ceramic media on top and two fine filters at the bottom.

I can actually see particles being sucked into the top space of the filter, from the water level grille, so I assume that I have the arrangement correct!

I dont use the nitrite or carbon filter.

There is also an inlet at the bottom /side of the filter, but I think it just circulates some of the water without filtering, for more flow generally, but less filter flow (to allow the bacteria time to work).
