lochdan Posted September 4, 2013 Report Share Posted September 4, 2013 Hey guys ... don't use the stuff myself but am in a discussion with a guy who has accidentally overdosed his tank with his API brand PH up chemical. I suspect this product uses Sodium Carbonate which I know has minimal toxicity to humans but how does it affect our little fishy friends? Given this may be a pretty large overdose ... what corrective action is needed? I'm thinking a decent sized water change (50%) but thought someone out there might have a more educated response than my "I guess that might work" answer Link to comment Share on other sites More sharing options...
Matmatmat Posted September 4, 2013 Report Share Posted September 4, 2013 I've not had it happen and I'm sure no expert on anything.. But every time I ever over dosed anything I did repetitive big water changes to dilute what ever it was. Link to comment Share on other sites More sharing options...
Donny@ageofaquariums Posted September 4, 2013 Report Share Posted September 4, 2013 depends on what fish they are, the volume of water etc many fish wouldnt care, but it would be so cloudy lol I would 50% water change, maybe more if fish were dying if they are not tho 30% will likely do it better still remove fish to another container, with their filter Link to comment Share on other sites More sharing options...

Donny@ageofaquariums Posted September 5, 2013 Report Share Posted September 5, 2013 Well I'd still water change it out long term a really high KH is unsuitable for an oscar. Link to comment Share on other sites More sharing options...
lochdan Posted September 5, 2013 Author Report Share Posted September 5, 2013 (edited) Thanks Donny .. that was the advice passed on last night The guy was smashing in sodium carbonate because his ph was 6.6 and he had been led astray by an 'expert' telling him he 'needed' to get somewhere between 7.2 - 7.8. Armed with this advice, and with his PH stalled at 6.8 he just kept adding more and more chemical. Sometimes I just feel sorry for the fish Edited September 5, 2013 by lochdan Link to comment Share on other sites More sharing options...
Donny@ageofaquariums Posted September 5, 2013 Report Share Posted September 5, 2013 without an actual test of the water its impossible for me to know the waters KH 7.2 to 7.8 is not a bad range to keep an oscar in Reefers are fond of saying never dose something you cant test and its good in theory but yea in practise its hard there aint no IAL test after all.
