Setting up a 50 for Angels and eventually Discus

First topic message reminder :

Just picked up a 50.. and redoing a 29... most of my tanks have been picked up used with an active gravel/substrate so cycling wasn't a problem. My goal for these two tanks will be to ultimately have 4-6 nice discus in the 50 and a few angels in a tetra tank. Both tanks will be natural plants of course. My plants of choice at this time (before all of ya with a ton more knowledge) are Crypts, Swords, and some Val... So, if you were in my position would you boil some soil in cloth sacks for the sub-strate or something else? My gravel topping will be close to 3 inches over what ever I put beneath it.. And do I even need anything underneath the gravel? I'll be seeding both of the tanks with the water from my 35 G water changes... the 29 over the course of a week with 2 w/c's on the 35.. and the 50 will take a bit longer.. or I might (sponge) a sponge filter off a local addict.. Any thoughts to add to mine or advice you'd like to offer up? Thanks in advance. Bill in Richmond, Va.

If you look online they will often have a stock check for stuff at the local stores depending how far away it is for you to go.

Three types of concrete sand.. no mention of the size of the granuals.. but.. wth.. give it a shot.. and they're only 2 miles away! Both lowes and hd...

Haha Nice well good luck I know the pool filter sand is #20 grit sand so something similar to that should work.

suggested is .45 - .55 mm... I'm not a metric guy.. but me thinks.. pretty tiny! <grin>
