Weighing foam caves

Can I use lead weights to hold down the foam pvc caves or will it harm the fish.

Leadwill harm fish

 

^ agreed

 

Picture? If it's foam, could you dig a whole and shove some pebbles in?

Don't use lead

Don't use lead

or glue rocks on.

Not sure how the op could glue them. Super glue melts foam, so does hot glue

Possibly aquarium silicone

 

Lead would take forever to leech enough to do anything. Plant weights are still using lead. If you're worried about it just use tungsten. They make tons of fishing weights in tungsten in case California bans lead for fishing.

You could also tie fishing line to it and suction cup the fishing line to the bottom.

 

If silicone works, just silicone to a piece of tile then bury the tile. Makes sure to wait 72 hrs to cure before you put it in a tank. (Not sure if silicone will melt foam)

 

Silicone won't melt most foams

 

Heck it depends onthe glue, ive used hot glue on foam without melting, but depends on foam type
