Adding sand substrate to a gravel tank
I have a 100L tank at the moment with pea sized gravel but on changing my ideas on stocking the tank I would like to keep corys when I do stock it (currently doing a fishless cycle) and so I would like to include sand in the tank. I do not want to completely replace the gravel with sand, rather push the gravel to one half of the tank and fill the other side with sand so i have both sand and gravel to have a bit of variety and keep all the tank inhabitants happy :)
Is this kind of thing possible? and what is the best way to add the sand to the tank? I have 0 experience with sand so dont want to just pour it in or something and then it sprays all over the tank. I would also rather not drain the whole tank as I dont want to mess too much with the plants/ornaments and am halfway through a fishless cycle.
This is my tank below, I was thinking of sweeping the gravel from the left side to the right and filling the left side with sand as the filter intake is on the right and sand on the left would minimise risk of sand intake and impeller damage.

I see nothing wrong with your approch; I did the same procedure when I added gravel to my sand substrate (and UGF units. The gravel is the underlayer for the sand - really works well. Never thought it would work in the lon grun but does even with vacuuming.)
Getting the substrate all to one side is easy and I did not remove my discus (but I did move a lot of wood and fake plants for each side.) That all said, you do realize this will do little for the corries - they will also work over the gravel and damage their whiskers, anyway. I still think the sand/gravel will look fine but if you are just doing it to spare the corries I'm not sure it will help much.

OTOH it's a lot better than not doing it. You'd need some kind of boundary between the gravel and the sand otherwise it will mix. Pebbles work.
As to sand, pool filter sand is nice and convenient, needs no rinsing. I'd take a large plastic soda bottle, rinse it well. Cut of the bottom and you got a funnel to make it land where you want it.

"I'd take a large plastic soda bottle, rinse it well. Cut of the bottom and you got a funnel ..." tallductie, now that is clever! +1 to that!

brilliant idea with the plastic bottle! thanks!
If I put sand in the whole tank so the entire substrate was a mix of gravel and sand, would this be safe for corys to use??
