Here's two websites for the sand:
ReefCleaners.org | Clean Up Crews and Macro Algae - Sand (40 pounds)
Reefcleaners only offer fine grade sand which is kinda small IMO
. Its almost like sand you find in a playground.
If you want some larger grade sand, marcorocks offer coarse, but I have no personal experience with it so I don't really know how big the difference is.
If your on a budget, cheap lighting would work for FOWLR
. The lighting is mostly for your viewing, doesn't help with growth very much.
If you're using RO
water, there isn't any chlorine in the water so the de-chlorinator isn't needed.
I would suggest the fire shrimp for looks. It does clean but is nocturnal so it doesn't like to come out into the open very much. A skunk cleaner shrimp is very good since it can clean your fish also and it is much more active than the fire shrimp. My skunk cleaner climbs onto my hand all the time and just swims around like crazy during feeding time, very fun to watch. Both shrimps are compatible with each other so you can get both. If you want multiple shrimps, stay away from a coral banded shrimp since it will attack other shrimps and kill them.
