hi guys,
i need to modify my refugium ###### sump to fit in my new skimmer.
Question, can i disturb my 3 mth old refugium sand bed...... ?
what my plan is, remove all the sandbed, micro algaes in the refugium, cut the glass partition in my sump to broaden the space.
once done, place back the sandbed amd micro algaes. once the sand is settled, run back the main pump....
will that crash my system?
need advise on this......
