GF and Plants Friendly Substrate?

I also have an underwater gravel filter would this be ok with it too?

Thanks Mat

I've finally got some aquatic plants established in my tank that are
growing
and able to survive the goldfish. My goldfish are still under 3 to 4
inches
but they love to rip up tender plants.

I have pea gravel in the tank. The fish are getting bigger now and I've
read a lot of warnings here about the fish swallowing gravel.

My question is, what if anything should I put in the bottom of the tank
that
will work for the fish and the plants in the aquarium?

Could I dump a load of marbles on top of the gravel?

Thanks.

Underwater,

I've had the same dilemma as you. I'm considering one of the following:

Sand substrate
No Substrate
Pebble Substrate

Still yet to make my mind up.
