Help, contaminate from manual co2 in tank!!!
I have a 260L Jewul Vision tank, fresh water.
I use a manual co2 which has yeast, sugar and water in. A much cheaper alternative to the other co2 kits. Problem is, we have just had kittens which knocked it over which, due to the volume of stuff has forced some through to the tank (probably a couple of days). I noticed when i got home 14:00 (04/02/05 tonight), that the tank was really really cloudy with several fish dead. I did a water parameter check and it turns out that i now have levels of ammonia and nitrites which i never have as i do regular water changes and i check the water every week. I've done a 30% water change and put in some toxivec which is a pollutant remover (I've never used this before, and was recommended by my local fish shop). My gut is telling me to do another change tomorrow morning (probably about 100%) change as alcohol, yeast and what ever else has made it's way into the tank. The tank is still really cloudy. I've now found another dead fish, and i think all my shrimps are dead. Any advice would be appreciated. Thanks Russ |

Then people construct cat-proof brackets for the DIY bottles. The fix is massive water changes for a few days. -- www.NetMax.tk |
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 |

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. -- www.NetMax.tk |

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. |

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 have two 2L soda bottles mounted inside one of those large white 10L buckets that restraunts use (I think they use them in the building trade too); they have a sealable lid, so I just made a hole on the lid large enough for the air/CO2 piping to go through, and it has the added advantage of containing a bottle explosion, should one occur, and keeping the ambient temperature stable (if you put an aquarium heater and some water in there in cold weather). I have check valves on each bottle line before the T-connection and one past the T-connection to the tank, this prevents either the CO2 getting into the tank, or the tank siphoning out into the bottles. I am also quite mindful of the temperatures of the CO2 and the tank, because one being warmer than the other can cause siphoning. i.e. you don't need to have your bottles tipped over if the tank water is warmer than the yeast mixture, for it to get into the tank.(rare btw., it's usually the other way around). I also use tank water for the bottles so this temperature variation is kept to a minimum. As a tripple safe guard, I have inside the bucket a 375ml glass jar, half filled with water, which I can hear (bubble counter) but also acts as a gas exchanger/buffer. I don't have cats or any animal other than the fish in the tank, so maybe I am being over cautious, but I have heard so many stories on the internet of yeast mixture getting into tanks because of various over looked things. I guess I am paranoid about, firstly, yeast mixture, and secondly, carbonic acid getting into the tank and killing everything and having the gas exchanger there is peace of mind for me. Also my bottles are lower than the tank (on the ground) which is against advice about housing and operating these rigs, but once again the exchanger is a "peace of mind" buffer too. 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. Well one thing's for sure - it won't happen again at your place ;) I thoroughly recommend mounting the bottles inside something the kittens can't get into, and if you use a buffer/exchanger and check valves there is less chance of the kitties pulling the lines and causing a siphon. If you put an inline joiner in the aquarium line, if the kitties pull the line, it will split outside the tank and all you will have to worry about would possibly be drunk kittens, some yeast on the floor if it siphons out, and a pH rise in the tank ;), which is better IMO than a cloudy poisoned 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! I have never had this type of accident (touch wood) so I can't comment from any sort of experience, but I read something on a site the other day which went along the lines: There isn't anything a 50% water change can't fix and 50% changing never killed anything - or something like that. So my advice (not experience) is to up it to 50% water changes until it clears. I would imagine the bacteria in the filter were killed off by the alchohol, so when it clears perhaps a complete media change? These are only suggestions, as I've stated, they are not from any personal experience with such issues. 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? I have heard of the CO2 slimes after an accident like this. I really recommend you outright replace the media. I'd say the yeast spores that remain in the current media will always generate this slime long after you have the water sorted out.

You ought to see what a cherry jello/CO2 mix does to a tank. Massive
dilution works... Bob "Russell" wrote in message om... I have a 260L Jewul Vision tank, fresh water. I use a manual co2 which has yeast, sugar and water in.

Russ I use one gallon juice containers. Much more stable. I haven't had a problem since I switched from 2 litter soda bottles. I use 3 jugs per 55 gallon tank. A real pain ...have to upgrade to pressurized CO@ pretty soon ;-) bob |
