Hyposalinity for 28 fish?

[Michael Benz]

Hi all,
I'm breaking down my tank and need advice on do hyposalinity. I have a manageable level of Ick in my 375G. I'm going to clean out the sand from my display so I thought this might be good time to re-start with an ick free tank if possible. I will be nuking my rock.

Below is my planned setup and fish list. I've heard a few fish like anthias have trouble with hypo but I would welcome your experienced advice.
Tanks: 70G + 100G rubbermaid - probably about 150g total water
Filtration: Hang on filter + very large skimmer
LR? Should I keep LR in the Q tanks or will hypo kill the bacteria on rock?

Can the planned Q tank setup handle 28 fish?
Fish:
Clowns 2
Anthias 5
Tangs 6 (all about 4-5")
Angels 5 (all under 4")
Dwarf angels 3
3" Trigger 1
Wrasse 3
Bangaii 2
Harlequin tusk

This is pretty aggressive. Actually, I should say that you may have issues with aggression. Are you planning on splitting the fish between the tank and the rubbermaid container and sharing the water between the two?

As for the LR, the bacteria won't be a problem at hypo levels. Any other life on the rock may not do as well. If you have algae or critters living in/on the rock it may die and cause an ammonia issue.

 

[Michael Benz]

Yes, I had planned to split the fish between the 70g and 100g rubbermade trough, both plumbed together.

 

[Michael Benz]

I also may opt for a 150g rubbermaid + the 70g aquarium, might be better in long run.

Hypo is ok for fish when you drop the salt and actually work real good you will see your fish get the best colors as you drop the salt .. I did hypo for 6 week and use cupermine too ppl said is not good to do both but I did .. the problem is bringing the salt back up .. I low the salt to 1.009 but it took me like 30 days to bring the salt back to the lvl on my DT ... good luck

 

[Michael Benz]

Did you have any anthias?

 

[Cheche]

Anthias tangs and clownfish

That is an awful lot of fish but you'd be OK with both tanks. Hypo isn't a great treatment IMO as it ONLY handles ich. Brook, Velvet, Uronema, and many others are not impacted. As it is, Hypo is difficult to do well, as water evaporates or other human error occurs the salinity can increase which should re-start your clock. I've always had more trouble with hypo than copper but many use hypo with success.

Sorry for the trouble, I hope this was helpful.
