I'm looking to have a mixed reef of LPS, SOfties and SPS. Any dangers that I might not be aware of such as Toxins released by one coral that may affect another?

purigen is from seachem. it is a premium synthetic absorbent. it is a polymer. it removes soluble and insoluble impurities from water at a rate of 500% better than all others. with minimal impact on trace elements. it raises redox,and polishes water. it darkens as it exhausts and is renewable with treatment of bleach. for marine and fresh water. this is loosely parafraised from product lable. i have not regenerated any of mine yet. be carefull of bleach. this will last up to 6 months before you have to regnerate. the only down side that i can see so far is that the polymers are very very small so you have to put them in a very fine mesh filter bag i run mine in a a canister filter. i was afraid of clogging if i put it in my media reacter.

Although there is some truth to this as Xenia are somewhat of a "Nitrate sponge", don't worry about it much. Any coral that dies off and melts away will result in Ammonia which will be broken down into Nitrate in your system.Just got done reading a thread about how they can release nitrate back into the tank if a colony dies off.
