This happens more than you might think. Then people construct
cat-proof
brackets for the DIY bottles. The fix is massive water changes for a
few
days.

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!

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?

Thanks.

Russ

I'd expect two or three 75% changes should do it. Two 30% would not do
enough (imo). All internal filter surfaces should be covered in a
bio-film which is somewhat slimy. An excessive amount is just too long
between cleanings I think. It's unlikely to be algae, as most algae
prefers high light conditions. It's unlikely to be Cyno (slime algae) as
a filter is too turbulent. Perhaps some diatoms (bacteria) but probably
nothing to worry about. CO2 injection can sometimes produce some very
interesting fungi and moulds.
