new lava rocks

[xxwolfpackof1xx]

i wont cause any spikes, but it will leech, a little tiny bit, like all rocks on earth they weather, so you're looking at a few hundred years until they completely disintegrate. if that gives you any idea . also you're using charcoal so anything you put in the water is getting absorbed out of the water column anyways.

sweet looks like the tank has a new addition i wish i could cut my anubias in half ( its to large to put on one rock) and get it to attach itd look really nice

i wonder how you are growing plants and also using charcoal though. the charcoal will absorb the nutrients in the water your plants may need. something to look into.

I bought a bag of lava rocks at home depot and rinsed them and boiled them and rinsed again. I have them in both my cichlid tanks, some in a corner of a tropical tank which is the baby fry hang out now and in my sons cichlid tank. ( 75, 2 55 g and 40 g) all my water parma are good and haven't had any floaters....
