I honestly don't think you can believe there is NOT a large bio-load on this
tank, the 3 tangs alone are quite the messy crew, but I may be way off on
that assumption myself. I think its the amount of turnover in the tank that
helps with any would-be problems. I'd hate to have a power outage for more
then 12hrs to say the least. a car accident took out a transformer a few
blocks over a while back and it was off for 8 hrs with no problems other
then my dreaded fears of what was going to happen to my tank, only real
concern ended up being the sump volume was within 1" of the top as I had not
rechecked it after adjusting on the overflow box one day. lesson learned.

messy or not its been discussed in other threads so ill just bring it up, conversion of
ammonia/nitrite and possibly even nitrate consumes alk *AND* your water quality is good,
the food they eat is also generally effects the bio load less vs some other large fish,
bio load isnt size, and as long as something consumes there leftovers. my FO has a high
bioload and just to keep the alk at moderate levels, I have to use one of the many
addatives there is nothing at all to consume ca.


or you really are totally off on your
dosing schedule


may be off but I have only been adding 25-30 ml daily. my 29 gets 7
1/2-10ml daily and I don't have this problem in it. and its full of softies
with the only real calcium users being a 6" pagoda and a 3 1/2" darasa clam.
the coralline growth in this tank is amazing me every day.

unfortunate for me it seams like "back to the kalk" on the
75.............which I hate doing btw.

try some turbo ca, itll raise the ca levels once you get them up alk will fall, and you
can go back to whatever your doing, though ill say again I *thought* b-ionic was a 2 part,
so dose the ca more than the alk part, if not go to a 2 part or build a reactor. me
likes reactors dosing anything is a pita!
