Guppies - internal parasites/bacteria

[orange guppy]

Hi,
It's been a while since I posted, however within the couple of months some of my guppies have begun to have clear(it sometimes has a whitish sheen under the light) poo, I have read many things on forums over the internet and it's difficult to tell what exactly are the differences between fish who have parasites or bacteria. The fish, as i've lost a couple, waste away, their stomachs end up flat rather than the round underside of the fish and then they die. The fish are fed flake food once or twice a day and frozen bloodworm/daphnia and algae wafers around once a week. The tank is 10 gallon, water is 23c : ammonia 0 nitrite 0 nitrates vary between 20-40, i've never been able to get them under 20, ph is 6.5. There are currently 3 adult females and one adult male and around 20-25 from (a week old to colouring up) I am in the UK I have used interpet anti internal bacteria, and waterlife sterazin, with no effect. The tank has around 20% of water changed a week. Any help would be appreciated

Thanks in advance

There used to be a problem with guppies dying with similar symptoms and having no results no matter what meds were used. This is why, for a few years, you were hard pressed to find guppies for sale anywhere. The disease spread quickly and wiped out many guppies pretty much world wide. Perhaps pockets of it are still popping up here and there?

I have searched this, I know it probably is in the rules somewhere but at the moment I can't see it, am I allowed to post a link to a blog I found to see if we are talking about the same thing?
Thanks

It is a bit weird .maybe your right carylnz.never of that problem before.
Good to know.
As for nitrates, i would worry about your levels. They fine.
My tap levels are 40ppm.
My tank levels are much lower because of the heavy planted nature.
Perhaps you. Could try some java moss in your tank. As it grows fairly
Quick, using up the nitrates you have. A liquid fertilizer would help
The moss too. Not essential tho, if on a budget .
If real plants not for you then dont worry about your levels.
Your big 2 levels are the main priority & yours are spot on.

Have a check of ya tap levels for nitrates.probably already there,
.mite put your mind at rest.

I had noticed ammonia in my tests, that i never had before.
I checked all my kit was ok. Stepped up water changes. But still had readings
. I checked tap water & bingo it was there. Not good

A link might be helpful orange guppy and within the rules.

I think Ady has a typo there (he has lots really but specifically I am referring to this one) and means "As for nitrates, I WOULDN'T worry about your levels. They fine."

Thankyou for correcting my cock-up carylnz ... That will

I will stick to the pc in future...

Thanks for the responses, Java moss may be good to try, although I may leave it out of this tank as if the fish have a bad disease it may be on the plants afterwards if they die, thinking about it I think the tap levels are 20 ppm, I think I measured them last year to check. I didn't even notice the typo . I found this blog, and although snails haven't died in my tanks, and it doesn't seem to kill the fish quite as quickly I have seen almost all of these signs on my fish : http://keeper-of-water.blogspot.co.uk/2 ... guppy.html , is this the type of thing you were referring to ?
