hippo tang sick??

Here is an interesting quote oh hyposalinity:

"Hyposalinity treatment can be a useful strategy in systems where it is impossible to get the fish out and treat them by a chemical method. You drop the SG in the tank to below 1.017 (some say as low as 1.009 but IMHE 1.015 is about as far as I would take it) in small steps around 0.002-0.003 units per day. The infectious stages of marine white spot, the tomites, can't survive the low salinity and die off. It can take a long time to cure a tank like this, at least 4 to 6 weeks often 12-16. In addition this treatment is very stressful for shrimps and urchins/starfish/brittlestars and some fish species that are sternihaline and do not osmoregulate well at low salinities.

It also plays havoc with your water chemistry and we make no apologies for repeating a comment Simon Garratt made concerning hyposalinity and the changes it causes to dKH and pH in a post on UltimateReef some time ago.
“Hyposalinity treatment is not a good idea in a modern reef tank using the Berlin method. It has drastic effects on dKH and pH stability.

SG dKH
1.025 7.04
1.020 5.36
1.015 4.16
1.010 2.96
1.005 1.44

At a dKH of 4, your pH becomes very unstable over a 24hr period with large dips at night, even more so in immature systems that commonly has higher degrees of algae present than older more mature and heavily grazed systems. Whilst severely detrimental to corals (especially hard corals) these levels can also cause a multitude of other problems as well.

Low pH levels are dangerous to all crustaceans especially during moulting which usually happens at night, this isn’t just your shrimps, it’s also your entire population of critter life in the tank that comes under this group, including copepods etc.

It also plays havoc with sand layers and the LR, causing big shifts in boundary layer function, possible dissolution of bound phosphates, and an overall destabilising of the entire nutrient cycling abilities of the tank.”

I also think that I would go to wetwebmedia.com and search tangs with ich. Bob Fenner, one of the worlds renowned salt water aquarium people has posted a lot of information there about tang...especially blue tangs with ich. I had the same problem, took his advice and everything worked out. Copper kills the fauna in the tangs digestive track!
But if copper is the way you want to go...it can work. You must test daily and keep the copper levels between .10-.15 to be effective to low it wont work too high your fish dies. Not worth the risk IMO. Use HYPO


I trust Bob!

My info is from a leading published academic who specialises in fish disease and treatment.
And marine fish don't get ICH. ICH is a freshwater disease (Ichthyophthirius multifiliis). Marine fish get marine white spot (Cryptocaryon irritans).

It's actually 'prolonged' copper treatment that harms microfauna present in its digestive system.
The emphasis here being 'prolonged'. A week is not classed as 'prolonged' imo as I know many people who have successfully treated tangs with a week long dose of copper at the correct ppm.

 

[cav]

0.10 to 0.15 is too low for copper treatment, it needs to be in the 0.2 to 0.3 range to have the desired effect.

I am done. I am trying to give other options and share things that worked for me. If you know it all by all means have at it. We are here to help and share new experiences not to put other people, their ideas, and techniques down. What works for some people may not work for others. It does people good to hear other people experiences and what works for them. But you seem to be so closed minded about other peoples ideas that only yours can be right and if anyone challenges that you get harsh, mean and rude. Goodnight

 

[cav]

I fail to see how any of my comments on this thread have been harsh, mean or rude. I have provided ample information on marine whitespot and its treatment and the downside to hypo.
Yes hypo works as does copper, both have its pros and cons but out of the 2 the vast majority seem to use copper treatment over hypo as it has been tried and tested for years.
Depending on the strain of Cryptocaryon irritans there is scientific evidence that some can with stand salinity as low as 1.004.
I think some people need to get thicker skin and not take all comments to heart

What we have to remember in this hobby is that everyone has their own way. Doesn't mean to say one is right, the other is wrong.

It's up to the OP to read through all the advice given and make their own informed choice.

:iagree: Well said, Ali.

Lets please remember that we are not scientists here, we just want a route which works to cure a parasite, infection or disease. We are all free to state our own routes to deal with an issue, however, we should not be arguing our own specific route..Simply state it, and answer questions posed on that route by the thread OP.

If its like me, i would use hypo to deal with MARINE ich...and yes, being part of Bob Fenners crew, i have never had him question why i recomended hypo and not copper when a person emails us and asks for help on Ich. Why? because both routes work, that is a fact. So, lets just listen to what people say and not try push other idea's aside. Many routes to achieve an aim is what makes us a community, and not a golden rule book..

So, lets keep this thread constructive and not argumentative.

Thanks..
