This happens more than you might think. Then people construct cat-proof

Cheers,

I've just done another 80L (30%) water change this morning. I found a
dead wiptail this morning, but all the other fish seem ok. I've throw
away the co2 bottle as i really don't want this to happen again. I'm
going to invest in a Proper pressurised dosing unit.

I hope this is a good warning to anyone using these diy co2 kits to
make sure that they are housed properly! As my tank is close to the
wall i couldn't hang the diy bottle from the back of the tank.

How many days do you think i should key doing these large water
changes to get rid of any pollutants? I've now done two 30% water
changes. It is still cloudy but i can now see the back of my tank!

You mentioned previously that you had high ammonia levels after the
incident. I'd keep doing changes for at least 2-3 days past the point
when the ammonia drops back to what you would consider "normal", and
even below that. Yeast and sugar in a nice warm tank? The yeast will
love that!!

Also, when doing the change, i cleaned the filter media (in tank
water) and it was really really slimy. Do you think i might have an
algae problem as well?

How often do you clean/change the filter media? Slime happens over
time due to trapped food particles etc. in the filter media.
