Sand for sump refrigum

[leonard2k]

hi there

Recently i trying to make my water crystal clear but it might take some time.

there is a few things that cause the water at my main tank to have micro particals

1) very fine sand (quite a bit)

2) Pods

3) fish's shit

4) micro bubble (very little)

i will like to ask what sand to use for sump refrigum?

i have a 4 compartment sump,

my 3rd is empty, 4th is return pump but there between them i can put filter sponge

notice those fine sand settle at my 3rd compartment, i might as well make it as refrigum compartment

what sand do u guys put in?

live carrbiand sand? i see see at some place they are quite fine.

As i see at some place that sell coral chip, they have this c-3 size which i think is just nice.

maybe i can get any sand that size similar to c-3

any recommandation?

Try getting Grade 0 - 1 for DSB. Alternatively if you are willing to pay more, you can try out caribsea mineral mud or Two little fish new sand substrate for your DSB which provided additional mineral to your tank as well as it helps to stabilize PH .
