I presume is ceramic ring. You should remove it slowly & at the same time, monitor your water parameters. The other thing to consider is whether your tank can handle the bioload w/o the cr & biohome that you are going to remove.

I will still hv biohome in my sump tank,200 bioball in my overflow box, skimmer and total 40 kg of LR,should be enough to handle the load somemore currently only hv 4 fish in my tank.

Bio balls are out-dated, & are considered nitrate factory. Try DSB & more LRs.

Bro,

u definitely have to remove gradually..... maybe 20% every 3-4 days, over a period of 2 weeks would be good...

CR also nitrate factory...if u are getting rid of your CR and bio balls, there is someone in the pasar malam thread who is looking to buy...sold all my bioballs and CR to him but I think he still needs more...
