Suthdown - tropical sand - ammonia/nitrites

Recently when I was swimming at Hervey Bay I discovered that if I dug my
toes into the sand up to my ankles my toes were in very cold sand. The
water temp at the time was disgustingly warm, almost warmer than my skin
temp.

Give it a little while for bacteria to get going and it will clear up.
The fact that it's taking a while to clear shows it's very fine
particles.
And down the road that will be a plus for ya. It is frustrating
and worrysome. But it will clear up for you.


This is my plan at this point, Ric. I am going to wait and see what
happens.
I will probably put there some piece of base live rock from a different
fish tank to speed things up... and maybe a couple of blue-legged hermits.
I plan to feed these little fellows and hope they will feed the bacteria
action
with their feces... ;-)

Have you read anywhere about temperature of sand in regards to DSB ?
When I was mixing the sand with my bare hand I have noticed the surface
is warm, but the lower layers of sand are very cold - are there any
problems
related with this issue and did anybody try to solve them using heater
cables ?
