Need some help with my Aqua-one 320 tank . I had to get a new tank to replace my smaller one in my study, due to tank leaking and cost of this was far cheaper than getting another orb or ube and its a great looking tank. I decanted the water from the old tank (19l) into the new one (28l) and topped it up with treated water 3 weeks ago. Every week I do a 10% change.

Does anyone know if Protozin & Melafix combination affects ph (poss lower than 6.0), nitrite (around 0.25ppm) and nitrate levels around 80ppm) ? Ammonia level seems fine less than 0.25ppm. I just tested tonight after 2 treatments and levels are as above, which aint good.

Normal tap water ph is really good here and I have no problems with my bi-orb (although after this I will be testing as soon as I clean the test-tubes)

After my 10% change yesterday, I found white spot yesterday on my 3 Black Neons, started treatment above immediately, but 3 neons & 1 zebra danio are now gone. Last danio has a red rear fin like blood patches on it and the fin looks as if its dropped at the back (like a broken back) and Siamese Figher has also just passed away. Black molly, algae eater and apple snail all look okay.

I have done a 30% change to bring the levels back down and have turned up the temp a bit to help speed up white spot life cycle in the tank.

One thing about this tank though, its an undergravel filter only. First time using this type of filter and reading about them on the net, im beginning to get very nervous about this. A lot of people are saying they aint the best to put it midly.

I have an Elite Stingray 5 underwater filter from my old tank, that is a biological filter. I think i will add this into the tank also to help filter out some of the bad chemicals... This is only meant for tanks up to 19l, but with the undergravel filter in place, then hopefully this will help things without me having to go to the expense of buying something else. My tanks holds 28l minus displacement etc so hopefully this should work.

I dont have any bogwood in my set-up, in fact everything in there is artificial, with the exception of my rainbow rock, which was in the old tank (and also have one in my orb), but even then, at the 1st sign of white spot I removed the rock as I didnt want it going blue like the one in my orb did when treated previously.

Anyone have any thoughts ?
 
How many fish have you got in there, and what kinds? 28 ltrs is quite a small tank.

When you swapped over your tank did you move any filter media or gravel?

Sounds like your danio has some sort of bacteria infection. This coupled with the appearance of whitespot does sounds like there is some sort of stress situation in the tank. Don't know what would make your ph crash though. :no:

I did have 9 fish in there in total (1 siamese fighter, 1 swordtail, 1 black molly, 3 black neons, 2 zebra danio's & an algae eater), all of them used to live in the 19l tank I had before this one. I realise it is quite a small tank, but these were all small fish and had all lived together in the smaller tank for about 6 months.

I originally set this up to house my Siamese as he was attacking everything in my main tank and I couldnt bring myself to get rid of him, im a sad sentimental bugger that way :)

When I moved them over, the only things i moved was the water and the decorations within the tank.

I have done the 1st three days of the Protozin treatment and the last one gets done on Friday, I have also been adding in some Melafix as well to try help any disease situation.
 
Whats your tap ph to your tank, it's cycling so you will have swings in ph, plus the red patches on the danio was septicemia i'm afraid.

PH usually is around 7.0 -7.6, so thats why this is confusing the hell out of me. Not sure its septicemia though, as the patches are going now and the fish has been very active the whole time (reading up on about this on the net)
