hi all, thanks for your replies - just wanted to say that everything is finally back to normal now! I've had zero readings for three days now! The ammonia level hovered between 0.25 and 0.5 for about 17 days and then all of a sudden (after a good clean, some removal of other suspects, a shell and a plant), went to zero. Then of course I had a nitrite spike! (Will this ever end I thought!) But after 24 hours that was gone too! Yeay for hardy nitrite munchers. So, disaster over - no fish lost - all is well. Thanks for all your insight and support over last three weeks or so! Lxx
hi fk, after 17 days of a persistent ammonia spike (here's the whole tale) and even with Cathy's very kind donation of gunky media, it went down and I thought horray, but alas is now back up again to 0.5ppm. I must now look to my actual filter as the cause as my tank is clean, nothing dead hiding in it, yet I have not over cleaned my filter I took it apart to check the impala and it was a bit gunky, but nothing major I don't think.
The water is flowing out the outpipe okay (a bit weaker than normal and the bubbles don't go as far). How can I tell that the water is being properly sucked through the filter sponges?
After a lengthy and mysterious ammonia spike and Cathie coming to the rescue yesterday, I'm pleased to announce my ammonia level is now zero. I think two rather pongy whelk shells were partly to blame. Boiled them yesterday for about an hour and they're not smelly anymore. Will keep an eye (nose) on them
So my question is thus:
Seachem ammonia alert - how long does it take to work? I bought on on Saturday and it sort of went to the lowest alarm colour after about 12 hours. And now that my API test is yellow, it's now not really any colour of any of the alert levels - grey more like. On their site it say it takes a couple of days to acclimatize. Is this what people have experienced?
Thanks for all the help with my panic over the last few weeks (esp fishlady and cathie). All is well and no one died
Hmm, the flow hasn't slowed per se, but it is quite a snug fit. Have removed a small amount of the media to give it a bit more room. Cathie's come to my rescue with the offer of filter media, so hopefully this spike (or rather now a 'table-top' graph) won't last much longer! Is it true that nitrite munchers are a bit hardier and may not have suffered as much? If they haven't had 'food' for a week or so will they die off?
Just had a thought - could the bacteria have suffered as I've 'over stuffed' my filter with additional sponges? A month ago I replaced the standard carbon filter media with a regular filter pad (I have a fluval U2 filter) which meant I had to stuff in a slightly thicker pad in place of the thinner carbon. I did this with both cartridges and when the cartridges are back in the filter it's a bit of a tight squeeze. The flow of the filter hasn't been affected though Sorry for all the pondering, I feel like Ms Marple
Would anybody mind giving me a piece of their filter media to kick start my cycle again? Here's the whole story, I would love not to spend too long cycling my tank with fish in it having been so careful fish-less cycling last year
I live in Hackney, work in Clerkenwell - can travel!
Thanks for all your advice and help. I've still got an ammonia reading (day 9 of spike) - it's not going up beyond 0.5ppm but I did a big water change yesterday 70% and that reduced it down to <0.25ppm. Nitrite is still 0.
No dead snails in the substrate and I've taken out the live plants. I'm just going to wait until the bacteria grow again and continue with water changes.
I have a few more q's for ya about water changes...
Question about PH, KH, GH of tap water.
I've tested my fresh out of the tap, de-nitrated, de-chlorinated water and results are as follows:
PH: 7.6 High PH: 8 KH: 12 GH: 17
My tank water this morning was:
High PH: 8.2 KH: 10 GH: 17
Is this okay to go ahead with the water change? The temp is the same.
Question number two:
Is it okay to use any of the (seemingly zillions) of test tubes for any test as long as they are well rinsed with tap water and then tank water (or the test water)? I want to ditch the boxes and just keep all the bottles together.
