Some of MFK members did that and his tank look great, I think he did it for his 75G cichlid tank.Has anyone ever used slate to like the bottom of your aquarium? No substrate just the tile.
I wouldn't do that, you will have a nitrate factory under the slate in long run.Was just thinking of fitting it in without the silicon. So it could be easily removed if I changed it around.
but all he has to do is ift the tiles out and siphon during WC. If he does once a week, won't be enough nitrate build-up to any ill-effectI wouldn't do that, you will have a nitrate factory under the slate in long run.
I would place them in an empty no water tank for few days. you can using that time to change thing to your setup before silicone them in place. I used this method for my 40B setup, I put everything together without water and of course light on to see if I like the look or not, change it around and silicone glued them in place then fill up with water .
