Coarse or Fine

What is the advantage if any to using fine or coarse sand for my fowlr 100g Ty

 

many!

do you want a deep sand bed?
when you say course do you mean crushed coral coarse or just sand with shells in it??

 

No I don't want deep 1-1.75 in but when I checked at macro rocks.com they asked coarse or fine Bahamas aragonite,Ty

 

I have had both and like corse better because it looks more natural.

 

Ty for your opinion,I'll go with coarse:

 

fine is possibly a bit more comfortable for sand dwelling wrasse species
also kinder IMO to any LPS type corals you want to place on the sand bed
its also less likely to have issues with rotting food, falling between the particles

the biggest drawback with very fine sand, is keeping it where you put it, in set ups with good flow

 

Very true. Also, though, I find snails tend not to like to crawl along fine sand and eat algae, so, I always end up with algae build up. Not the case with coarse sand. Snails don't seem to get stuck in it and are more willing to clean it. A medium grain is a nice compromise, so, that is what I use. Doesn't seem to cause problems with the sand-sifters, CUC cleans it and it dosn't get blown around with my MP40.

 

coarse for me alot more flow and I can vacum it if i want alot of people dont like to do this but it has worked for me so i do it lol

 

Base the decision on your stocking of the tank. Burrowing fish like some gobies won't like a sand too course.

fine, yea its more likely to blow around but coarse grows algae on it.
