Hypo and Chemiclean?

[leewish]

Currently i have pulled all my corals and inverts and I am running hypo on my display tank. It was my only option given the tank is 180 with a good amount of fish in it.

Right before hypo I was considering adding chemiclean. I'm told its more of a last resort to use and a temporary fix if you don't find the source fo the problem. However as I read about it I saw that it depletes oxygen and you should continue to run your skimmer and put in airstones.

So my question is given I am running hypo right now which adds oxygen to the water, is now the perfect time to consider running chemiclean?

Hypo does not add oxygen to the water.

Ok. Thanks Steve. I was hoping you would respond.

I thought fish were able to breathe easier in hypo b/c of less salt creating more oxygen.

Thanks for clarifying.

They can osmoregulate (which is good) much easier. Not the same thing.

The solubility of oxygen in water increases as salinity is decreased. So, while lowering salinity doesn't add oxygen per se, it does increase dissolved oxygen. Improved osmoregulation is an added benefit to the fish.

While true, the context was in conjunction with Chemiclean. Algaefix and similar products remove oxygen from the water which makes the solubility of oxygen increase moot. As such, with fish having gills with likely parasite infestation, oxygen removal could be catastrophic.

Hypo does not add oxygen to the water.

Well, this isn't entirely correct.
While hypo doesn't actively add oxygen, the lower salinity allows a higher saturation level of oxygen in the water.
So yes, hypo effectively increases the available oxygen for the fish.

Except, of course, if a chemical that depletes oxygen is added. Which was the context of the original question. Lower salinity does allow greater dissolved oxygen as would lower temperature all things being equal, which, with a chemical additive, they are not.

Would you consider chemiclean in hypo or is it a bad idea? Its so bad that even my spiny box puffer (just lost) had cyano on his spikes. My thought was waiting til the last bit of dots are gone before I would use it but wanted opinions first. Did not want to do more damage to the fish.

Chemiclean is Chloramphenicol, a broadband spectrum antibiotic, and the given dosage is calculated for normal salinity. Doing it at significantly different (higher or lower) salinity is very risky business.
