please help, problematic tank!

Hi Guys, new to this site, hopefully you can offer some advice, here's the deal;

30 gallon interpet/resun river reef nano tank. airstone, fish only, 7 kilo's of live rock, 6-8 weeks old...

current water conditions (an improvement on yesterday)

ph 8.2
ammonia 0.1
nitrate 10.0
nitrite 0.3
salinity 1.021
temp 27 degrees celsius

we experienced a spike after moving the live rock and doing a gravel vac

stock

stars & stripes puffer (2 inches)
porcupine puffer (2 inches)
common clown (1/2 inch)
valentini puffer (1 inch)
humbug damsel (1/2 inch)

everything was fine until about 3 weeks ago when our porcupine puffer started suffering from whitespot/ich. although tbh it could be velvet. have tried 2 different medications now, firstly esha oodinex wide range (seemingly no effect) then waited 48 hours and tried octozin flagallated protozoa on the advise of my lfs. seemingly still no effect, the porc and the s&s both seem lethargic and look visibly ill... as I'm typing this they are both sat almost completely motionless. however not breathing heavily...

any ideas?

Regards



Ben

done that, 2 pumps running, a reasonably big airstone plus a koralia nano powerhead/fan

without the meds how do i treat the ich/velvet
