#ed_op#DIV#ed_cl#If my tank has cycled and is good to go, can I add more live sand to it like six months to a year later or will this cause problems for me?#ed_op#/DIV#ed_cl#
agreed, you do not want to add too much at a time or you will have quite a bit of die off and see a spike in your parameters. I agree with angie about a quarter inch at a time
If it were me,I'd keep the shallow sand bed in the display and do a remote DSB in the sump.SSB have been very succesful for me in the past,the ability to vaccum/siphon the shallow sand bed keeps the bed from getting clogged with detritus/organics.There have been many studies as to whether or not SSB's are capable of de-nitrification and according to them,they are.
