Posted	White Spot and Protozin
26-07-2005 10:41 by Matt	I have had an outbreak of white spot in my tropical tank. Water conditions seem fine, so I have treated it with Protozin and I have two concerns. Firstly protozin is a deep blue colour and quickly colours the water blue, however after about 20-40 minutes the water is back to its usual colour. Is the protozin being filtered out (I have removed carbon from the filter)? Also the white spot seems to be getting worse, I have treated on days 1,2, and 3, and was expecting the sports to be clearing up now. With a fourth dose on day 6 just to finish the job off. Is it something that needs to get worse before it gets better? Any help would be gratley appreciated.

You could try octozin if this fails it works differently from other remedies or alternatively WS3 if you can get hold of it, its a concentrated remedy or alternatively contact waterlife direct and discuss your problem with them they may suggest a higher dose than usual to deal with it.
26-07-2005 15:10 by Matt	I have only got a Fluval 104 filter, now with just the foam pads and biomax media after removing the carbon. No zeolite, so I can't see what would filter the protozin out. So I am right right in thinking the the blue colour should stay longer? Thanks for the help anyway, I may need to contact Waterlife, after all it's their product. Cheers
27-07-2005 07:50 by Alan	The blue colour doesn't stay long but it doesn't mean the chemical arent working but it would be best to discuss it with waterlife as I suspect you may have import spot which is a resilient form of white spot.
27-07-2005 09:58 by rob	the white spots on the fish will not be killed by the treatment as its already passed the stage that the protozin can kill these have to die off naturally its the following generations of the parasite that the medications kill off this is why you must complete the full course of treatment and not stop when you find no more white spots on the fish or you will get a new infestation a week later
27-07-2005 12:52 by Matt	This must be some sort of super white spot. Yesterday morning all fish were looking fine, spotty, but not in bad health. However last night some of my tetras (bleeding heart and neon) were looking oxygen starved, so I increased aeration. This morning 5 tetras were dead and few more well on their way. I can't beleive the speed it all happened. Interestingly my corys and plecs are fine, no white spot at all. Could this be due to their different skin types, as they don't have scales?
27-07-2005 13:07 by Alan	One of the worst things about white spot is that it can get into the gills this is where severe damage can occur. Have you completed the treatment now? As Rob says it is important to complete the treatment as the parasite can only be killed in the free swimming stage. The import spot I describe is resilient to most treatments at normal dosage hence why I suggested contacting Waterlife to discuss your problem. Are you certain it is whitespot it could be velvet and I'm not sure if protozin can deal with both but it probably would as most treatments operate on a shotgun method killing a variety of organisms. Some fish are not susceptable to whitespot or have a certain level of immunity to the effects of the parasite just because you are not seeing the effects on them doesn't mean they are not infested. There are some more options available have you increased the temperature of the water? It is always a good idea to do this when dealing with whitespot it speeds up the life cycle of the parasite meaning the treatment will hopefully dispatch the parasites sooner. If you have no luck with Waterlife try using a treatment by another manufacturer I have had good results with WS3 and esha products in the past it may be the infestation you have is resilient to the combination used in waterlife's treatment but won't be to other treatments. Your problem probably results from some failing to iradicate whitespot in a tank or with one of the fish you have properly in the past creating this resilient strain. This problem could go all the way back to the exporter of the fish in south america or where ever else your fish originate from.
06-05-2006 20:27 by ajrel	I have the same situation as Matt. I am using Protozin, have fish with spots, and wonder why the blue colour disappears after about 20 minutes. Also, I am finding that the tank is hazy (day 2). I am supposed to treat days 1, 2, 3, and 6. After day 6, should I do a water change?
06-05-2006 20:33 by kell	have you took the carbon out of your filter
06-05-2006 20:37 by kell	also it should say in med instructions when to do waterchange.
08-05-2006 09:50 by Alan	Do a partial change on day 8 if the spot has not gone do a series of water changes diluting the remaining remedy and then stop using waterlife as I have found their remedies to be ineffective recently. Try one of the following: Esha Interpet Sera costapur WS3 Or go for the raw chemicals normaly sold as pond remedies you want a malachite green formalin mix or alternatively go to town with a copper based remedy any inverts will be killed by a cooper based remedy though and also any mormyrids and possibly some knife fish will be effected badly and probably will die if you use copper.
08-05-2006 09:52 by Alan	As far as the colour going with protozin it is not a problem, it is only the dye dissapating. When using a Malachite formalin mix have the lights out as malachite green breaks down very quickly under light.
