Hi I desperatly need some help. All my fish are dying. 6 died today. I don't have any idea what to do. It is a large tank, I think tropical (set at 28 degrees celcius). I've changed the water a couple of times but they keep on dying. They are all swimming near the top... Is that normal? They don't normally do that. What should I do???

I'm not familiar with "water ager." What conditioner are you using?
Do you test you tank for ammonia, nitrites and nitrates? Are you familiar with the nitrogen cycle? What are your normal hubandry practices (frequency and amount of water changes)? What model filter are you running? How big is the tank? What do you have in it? How long have you had the tank? Have you done anything different to it lately (changed conditioner? Added new fish?)
If your tank has been established for some time, excess ammonia or nitrites shouldn't be a problem unless you've done something to kill off your biological filter. Nitrates, the end product, need to get pretty high to be harmful, and are ultimately maintained at safe levels by your water changes.
If you don't have test kits for the above-mentioned chemicals, get them, or at least take a water sample to a fish store that will test it for you.
Fish swimming near the top may indicate a lack of oxygen in the tank. Is your filter moving water in the tank?
Give us more details on the tank. I know I asked a lot of questions, but we need the info to help.

Thanks heaps for your help.
It's about a 2.5 foot cube tank, tropical freshwater fish, one big red devil, quite a few cichlids (i think). Temp set at 28 degrees celcius but it's been pretty hot the last couple of days.
It's my dads tank and he is away. We've had it for a few years. Haven't done anything new to the tank. No new fish.
We've changed the water, water age-r is a conditioner (probably an aussie term).
The filter is definitly moving.
It's 3am and I don't think I can get much more done tonight. I'll call someone to come have a look at it tomorrow.
But thanks for all your help,
Let me know if there is anything else that can be done...

How high is the temp? High temps can result in low oxygen levels, which will force the fish to move to the top of the water, where the gas exchange takes place. Additional surface agitation may help. 28C is about 82F, which is pretty warm, so if it's gone much above that, this could be the problem. Low O2 will stress fish, and make them more susceptible to other ailments, as well. If the tank is actually a cube, 30x30x30, it's about 115 gallons, and fairly deep, meaning it will take more to get the lower levels of the tank turned over. What kind of filter is on it? Where is the intake and outflow?
