Cloverleaf CL3
Morning all,
I'm after ideas please....
I have a cloverleaf cl3... a good bit of kit and feeds my waterfall.
I'm thinking of changing internal media.
Current is ;
Vortex
Brushes
Japanese mat
Alfagrog.
The filter is downstream of drum , then moving bed, I was thinking of...
Removing brushes as they don't do anything, putting the jap mat in place and then having 2 bays full of alfagrog....
Any thoughts or ideas very welcome please..

To me your correct in the point of it shouldn't be doing anything so yes I would remove them and add more media it's more beneficial in my eyes even the vortex shouldn't really be doing much just my novice opinion

How about some CSM instead of grog . I've used grog before as it works and is cheap but found the crap it can hold is no ones business like . . Hear a few people say it still collected crap even after a drum with all the deep holes in it and that will just sit there rotting

Thanks whitey and AJM
CSM is an option,
Google reckons best in showers though, in the bay will be submerged.
Whitey, your right vortex is spotless after a year!

Ricky has said in one of his youtube videos that shower media submerged is no good,
as it will perform better nitrification in a shower, no doubt.
but it will also out perform most other media types on surface area alone by a factor of 10-100...
i remember reading momotaro also uses his shower media submerged in his filter bays too.
if you have the space why wouldn't you?
there is also an argument that some denitrification would take place, and better than it would in a shower, due to the slightly lower levels of oxygen.
and speed of water pass through.
they have been using solid blocks of pourous ceramic media in marine reef filtration submerged, for that purpose for some time now.
but don't underestimate brushes, they can trap a shed load of fine particles better than a tempest would imo....
but the vortex is largely redundant after a drum, i'd move the brushes into that and add CSM in the other chambers,
but remember that removing part of your old media will reduce you filters maturity.
how old is the new moving bed?

Hi Dave,
Drum and moving bed are 18 maths now.
CL3 is 4 years
Good idea to slap the brushes in the vortex,
Then have the jap mat next,Then CSM
Then final old grog...
Sounds like a recipe lol
