Alright so i currently have pool filter sand in my 75 gal but after seeing the effect of how black sand brings out the color of my fish in my 20 gal i kind of want to switch to black sand. So should i switch to black sand or keep the pool filter sand?
Btw i have a wolf fish and tiger Oscar in the 75 and i wanted to get the wolf fish darker with the sand.
