Removing coral chips

[IIIEEE]

Dear all, I am thinking of replacing my coral chips with biohome. I remove 1/4 of the coral chips and placed 2 kg of biohome into the sump. I noticed that one of my fish actually has a bit of fin rot. Hmmm. Could it be due to ammonia spike?? Can someone advise on the procedure of making the change?

Another question would also be, I am planning for a refugium. Can I just get some Chaeto and have an LED light set to shine on it for 24 hours? Or it will be better to be on a revise cycle. Thanks for your advise

Hai, I would suggest minimum arrangement our sump to avoid stir up or resurrected badthing from sump (bacteria)... siphon dirt should be ok...

If afford to stop return pump a while until your maintenance works done and makesure all the residual clean up. should be safer

About refugium, pls find below some nice refugium and sump setup from melevsreef. and yes you can uses chaeto and LED light set to shine on them.. 24hours or 12 hours.. Slower flow rate will be good..

Ya me too feel that u have actually accidently stirred up your sump to result in this...

Even when I siphon dirt from my sump I also do with minimium movement wor.

chaeto needs a dark period to be more effective, that is what i gathered from trawling e net anyway.
