today i changed my aquarium from saltwater back to freshwater (it is a 125 gallon tank)
i drained ALL of the saltwater out, took out all the Crushed coral, all the large rocks/coral
and washed the entire inside with freshwater twice.
i also washed the filter very well and the media extremely well
there was nothing in the aquarium at ALL
then me and my gf washed every bit of crushed coral (approx 15 gallons worth) very very well until the water was crystal coming out of each batch, i even tasted a bunch of the batches with no problem
put the crushed coral back in, put two very well rinsed pieces of large coral in and put all 125 gallons back in
with the filter running and everything we put the test fish in and it lived all of 20 minutes before it just died almost instantly and rose nose first to the top at which it was going from dead to alive like an on off switch every 30 seconds
i hurrily put it in a container of pure freshwater w/ a huge airstone
but within 5 minutes it was dead
it never really gulped for air at all, so its probably not oxygen related
the specific gravity is at 1.00
which is freshwater... right?
is it the crushed coral?
a chemical still lurking from the saltwater
i put a bag of activated charcoal in the filter to hopefully absorb the problem
im gonna wait 36 hours before trying again
any opinions are appreciated
also, im gonna keep large fish, should i run my protein skimmer on the freshwater tank? or is it not useful
