why does this keep happening every time i try to make a new post! why does it start a thread in someone else's thread??? Mods you should try to fix this!!!!!!
I would not use tufa rock. I would go for ocean rock which is denser and will displace more water but dosn't have the same problems tufa has. tufa can absorbe organics and phosphates etc and dump them back at a later date.
ahh interesting! One of my friends who has a 30g sw tank told me I should get some, and I thought I should have a second opinion. I don't think i wanna mess around with that stuff then. Thanks for the tip
