Help: Foam and Drylok ornaments
I will be leading a skill-building project with 12 to 16 year-olds working on various aquaria. I wanted to add a DIY ornament segment using the 3D background procedure as a model for a smaller ornament (as they will be working with 10-gallon tanks).
Drylok seems to be the safest option so far, so I was wondering if this would work:
Taking the itinerary into consideration, I wanted to have them carve the foam and paint it with acrylic paint. The next day they would apply the drylok and silicone the ornament to a piece of slate to make sure it isn't buoyant. The piece will be allowed to dry for 2 full days.
The ornament would then be placed into the tank with the plants. Is this long enough for the ornament to become try? Would the fish be ok to add the day after?
Thanks for any help!
Also, I realize that fishless cycling is the preferred course, but it is not possible within the 2 weeks that this project will last. Therefore, they will be doing daily water quality checks and at least 2 water changes per week or as needed.
