i was wondering about that. how long does it take for it to shoot the new plants off of it? in a medium lights tank? its taken off after it melted.I agree that a soil substrate really isn't needed for the plants you want to grow.
As for the crypt it's not a stem plant so you can't just trim and replant. If it has grown any "offshoots" you can divide those...otherwise you would have to move the whole plant, root system and all...
do i really need to do the plants? i might can just get new gravel maybe. how many of bags do i need of the kind from walmart?I bleach mine. You just have to know how much water to add with the bleach. I don't know if it will work on gravel but the plants can be bleach dip. Don't let it sit in the bleach water. You can also use other stuff to clean it but found bleach much easier to get. After, soak the stuff with conditioner to take away the bleach. I've grown all the plants listed with only 15 watts of light. No co2, ferts, nothing. I would just put gravel in the tank to be safe for shrimp.
it still says organic though. i REALLY dont want to redo this tank. i thought alot of shrimp like brackish water though.
