Aquarium Advice FINatic
That would have been a good idea. I wish I knew that last week! LOL! I' m done cementing the wall so I guess I'll just cross my fingers now and hope I get it siliconed heavy enough the the floor and walls so it doesn't float away!
awesome! Can't wait to see it.
One last alternative to silicone. At the end of my video I showed what I did. I'm not sure if it will work for yours but might be just what you need since its not a background.
I cemented some iron weights to the bases of my "rocks" and it worked out very well.
