Sump

[spicyball]

Hi ppl, i'm wondering what to most ppl put in their sump tank. Is it a must to put those filtering mediums such as sponge and carbon in there?

[terryansimon]

if not, then put where?

[Mellow]

yup, people normally put in 'unsightly' stuffs like carbon and certain filter media into sump. In addition, u can hide your protein skimmer, and some of the equipments in your sump. kindda makes your set up neater...

LRs are natura bio-filters...

Ya.. I used to have bioball & bioring + cotton wool in sump, and my NO3 has never stop increasing.

So I replaced all bioball with LRs, leaving the bioring and thin layer of cotton wool at the moment. Now my NO3 is stable or at least don't double up in just 2 weeks.

Deepblue is right, using LR is a natural bio-filteration. Let the nature do the job for long term solution. As long as you don't overload.

Currently my tank has 60+kg and sump has 20+kg of LR for my 150gal tank.

LR for in sump, i rather keep micro algaes to reduce no3.....

im also having @ 80kg of LR in my main tank......

the question is, why do u need filtration in sump when u have plenty of LR in main....

doesnt it fit any purpose .....i rather reserve my sump space for other stuff....

Cause I dont want to mix the normal LR with my big LR from CFarm. Doesn't match at all.

And since the 1st compartment of my sump is design to put huge amount of bioballs, I can't put any useful stuff in except LR. Of course I still have sufficient space in the 2nd and 3rd compartment to put other stuff and 3 pumps.

On top of that I have a refugium with lots of macroalgae and sealettuce to export nutrient with 36W PL 24/7. Observed for 2 mths, seems like it doesn't help much, and cyano keep growing there until recently under control.

Another possibility maybe due to my 6"-8"DSB in main tank maturing.
