It will definately not be enough of you are thinking of setting up a DSB.

DSB should at least be 3/4 the size of your tank with sand up to 4 inches deep

And I can see that some of your macros are starting to die, probably because of insufficient light or other trace elements

what's other trace element do we need ? iron ?

no offense....

but u are seriously way way way way out in setting up a refugium....

to my knowledge and way of reefing...

for a DSB to work.... it must have a huge surface area in addition to the deep sand... water must be allowed to flow slowly over the sand.... macro algae.... quantity the more the merrier.... light pref to be on 24/7....

for a sump yr size.... at least half of it.. should be refuge.... to make it at least decent...

That means i need to add more macro algae excluding DSB. Will this help?

[jd_n]

ur sump doesn't have the space needed for a sucessful refugium. so dun waste money buyin more macro algae.

Yes, I agree. You should get a new sump with bigger area for the sandbed if you are going to do biological filtration
