Orb,
Don't get confused
That said use what works. 5 drops per 10 gal is okay. You should be able to see it on the tests which is the important point
The initial version of this post included an inappropriate admonision to orb regarding hijacking the thread. I did not ever intend this to be as harsh as it appeared (hence the smily face

) I also simply read the prior post too quickly and thought thee was an intent to add a discussion of another tank cycling. I do not beleive that was a correct read after re-reading the materal so my apologies to orb and any one else offended by the remarks made in haste.
