aquarium switch out, filter advice, livestock check

[kvnkne]

Hey guys, I have 6 aquariums in my home and Im looking to swap out. I have an 80 gallon bow saltwater with
150 lbs. live sand,
80 lbs of live rock,
using a marineland c350 canister filter,
2 maxijet powerheads
with 4x t5 1/2 actinic,1/2 reg light.
It has been set up 8 months. 2 months ago I had a huge crash due to cryptocaryon. Live Stock was:
2 Mated Occelaris 3 in.
1 Skunk Cleaner 3 in.
5 Green Chromis
1 Lemon Peel Angel 3 in.
1 Flame Angel 3 in.
1 Niger Triger 3 in.
2 Firefish Gobies
1 Red Bubble Tip Anemone Medium Size
Water parameters have not changed even during outbreak:
ammonia 0-0.25
pH 8.2
nitrite 0
nitrate 20
salinity 1.024
Temp 80 F
Now all livestock left is:
1 Chromis
1 Skunk Cleaner Shrimp
5 Turbo Snails added due to algae growth
I also have an outbreak of red slime but not all that worried about that.
Per the move, I was thinking of changing all this into a 75 gal. with an older wet dry trickle filter that has been set up as a fresh water tank for years, containing:
2 Oscars 6 in.
4 Silver Dollars 3-4 in.
1 Highfin Pleco 5 in.
There is no skimmer or prefilter on this trickle filter. I can install a pre filter before the bio-balls or just place sand and live rock into the trickle. It is an older model made from lake reef systems and no research available online about it.
My question is issues about the canister filter being the only filtration other than the sand and rock in the 80. Is that would it be in my best interest to switch the two tanks and inhabitants?
Any advice would be greatly appreciated.
Thanks

Here is an interesting article on the survival of fresh water bacteria in salt water http://jb.asm.org/content/21/4/287.full.pdf
The other problem I see is that a trigger needs a larger tank than even the 80gal to live a healthy life.
Bio balls are a great for ammonia bacteria growth, but without cleaning them they will cause high nitrates. Canister filter are not my favorite filtration they depend to much on mechanical filtration then bacterial filtration. So I say use the smaller set up. But you need to adjust your fish load to match.
Tip, set up a QT so you don't encounter more parasites or disease.
Good Luck

you need to get all your fish in the QT and treat them at same time. Let your DT stand fish-less for 6 weeks to kill off parasite.
