80F
1.025 sg
Penguin 100 Bio-wheel
One Maxi-Jet 600 ph
20 lbs lr (semi cured - has some die off but does not smell)
20 lbs Aragalive sand (aragalive sand has 400,000,000 bacteria per 20 lb bag)
After 19 hours of cycling

It seems to be going through a very fast cycle. Does this seem normal? :notsure:
