Do you or anybody know what harmful affects the aluminum can have?There is some discussion on the marine pure leaching aluminum. Tandy Holmes-Farley experimented with it and found it to be true. I'm not positive what effects this would have on the tank just thought I would mention it. In place of the marine pure maybe you could use some small live rock rubble.
I do not. If you do a search on R2R for randy Holmes Farley and aluminum you should be able to find some info.Do you or anybody know what harmful affects the aluminum can have?
