I have vases with glass stones and fake plants in all of my bare bottom tanks and I love how they look and LOVE the bare bottom, but what I am finding is that food and debrise gets trapped in the vases and I am worries about rotting debrise fouling the water. I do try very hard to clean the vases out with water changes but i am finding that I have to take everything out of the vases and then put it all back together in order to keep it clean.
What i was wondering was if there is a product that would be clear and safe to use to fill in around the pebbles and plants so that I would not have debrise falling to the bottom of the vase but would be safe to have in the water?
I have read about people filling hollow ornaments but what is used?
Thanks in advance for any suggestions
