Yes. The sand will have much more benefit to the sytem as apposed to CC
. Not only will the sand trap much less detritus and other water quality degading items, it also has much more surface area for needed bacteria.
The gravel i have is TMC gravel of various sizes: fine, medium and coarse.
If i was to replace it i was thinking of getting some live sand from STM:
but i wasnt sure between the STM aquacultured live sand or the ultra fine marine white?
I would actually suggest you purchase the Sugarfine Aragonite and possibley a small amount of the live sand as a thin top layer. The only benefit there will be the claim of "calcious sediment from our rock bins"
which should benefit the growth of coralline algae. Since you have LR
, that in itself will seed the sand making the need for LS
redundant and an unneccessary cost.
If you were to change over and put new sand in,how would you put it in so that it didnt cloud the water column too much?
Just so happens we have such an article here >> How to change out your substrate
I've done this myself with 2 different tanks and it should be a snap. Preparation being key
