Do i need to change the coral chip if i had place it into the tank for a period of time?

Hi Bro,

If you meant coral chip placed into the sump, these used to be commonly practiced as some believed that it will support nitrifying bacteria and also assist in buffering the KH.

However, with the advancement in reefing husbandry, most reefers no longer uses coral chips as its been known to trap detritus if not clean periodically.

As for its buffering capabilities, its been proven that bacteria biofilm build up on the coral chip will reduce the abilities for coral chip to buffer a reef tank before its too late. Coral chips will need a pH of 6plus in order to effective buff up the tank but by the time our tank pH reaches below 7 - our tank would already crashed.

HTH ;)

thank for the advice.

How about the bio ring?

Hi Bro,

IMHO, bio ring especially the sintered glass type are excellent harbours for nitrifying bacteria. Thus they will be great to control ammonia and nitrite levels in our tank provided you ensure that there are no detritus build up.

But do note that the end-product of nitrification is Nitrate, so it is better to complete the cycle by having denitrifying activites in your tank. This can be done by having Denitrator or macroalgae refugiums or anaerobic zones in some part of your set-up etc.
