refugium

[dr evil]

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......

*tagging on* as I will be getting a new sump and intend to use my old DSB to put in the new refuge. How long should the sump be isolated from the main returns?

The last time I disturb my Sump, about half year back

it was already about a year old.

I dig out all the coral chips and replace by live rocks.

Lucky no casuality

Stop your pump from drawing water into the main tank

Do whatever work you wanted to

remove all water from sump

inject 'fresh' water
