nicmack Posted November 8, 2007 Report Share Posted November 8, 2007 Did some water tests in my tank the Ph is fine, Nitrite at 0 but the ammonia shows levels at 0.25 is this getting to the dangerous stage? Quote Link to comment Share on other sites More sharing options...
Ianab Posted November 8, 2007 Report Share Posted November 8, 2007 Not really dangerous.. yet. Thats probably about the lowest level the kit will detect. Is the tank new and still cycling? Cheers Ian Quote Link to comment Share on other sites More sharing options...
SpidersWeb Posted November 8, 2007 Report Share Posted November 8, 2007 Fish will tolerate 0.25ppm @ pH 7.5 I've found, but anything more caused gills to burn. If your pH is 7 or below it has a much less toxic effect on the fish (but do not use pH adjusting chemicals). Ammonia and Nitrite should always be 0 unless the benefical bacteria hasn't got a big enough population (e.g. new tank, sudden changes in tank stock or feed, filter turned off too long). If it goes to 0.5 or higher you should do partial water changes. Ian has asked the real question here, how long has the tank been setup?

jn Posted November 8, 2007 Report Share Posted November 8, 2007 If your tank is just starting to cycle you'll start seeing some nitrite at some point so keep testing for that too. Quote Link to comment Share on other sites More sharing options...
nicmack Posted November 9, 2007 Author Report Share Posted November 9, 2007 tank has been operating for a year but I added a second cannister filter to the standard aqua one filtration system however the new cannister filter is going trough the old filter, they are working in conjunction so I wouldn't of thought I would get an ammonia spike Quote Link to comment Share on other sites More sharing options...
Ianab Posted November 9, 2007 Report Share Posted November 9, 2007 Sounds like the change has upset the filtration in some small way. Maybe there is a lower flow rate through the new setup? I suggest you just keep an eye on it and it should go away in a few days as the new media starts to cycle. If it gets worse do water changes as a temp measure to keep the level down and double check your filters are operating right.

nicmack Posted November 9, 2007 Author Report Share Posted November 9, 2007 yeah its been operating since labour weekend sunday so I am going to pull out the old filter an give it a good clean out and the impeller head etc as it might be blocked it started out with a much better flow but I think its got blocked with gunge I should clean it out using the tank water right?

Ianab Posted November 9, 2007 Report Share Posted November 9, 2007 I should clean it out using the tank water right? Yup, just rinse out most of the gunge in a bucket of old tank water. Dont try and get it really clean, just unblocked. Do that whenever you notice the flow has slowed down. Otherwise leave the filter and it's gunge alone to do it's job Cheers Ian Quote Link to comment Share on other sites More sharing options...
