Well I'm in UK and they are off the chart but DEFRA says 50ppm is the legal limit?!?!?! :/ :/

I'll certainly have a look at the papers and see if I can help! My dissertation paper was on mosquito reproduction :/ I'll check ammonia tomorrow and if it's gone will assume all is well, only thing is high nitrates in tap water but can get products for that :)

Only thing is, tap water nitrates are pretty darn high, so prob gonna have to get nitrasafe or something as doing water changes is not going to bring them down!

I think the algae product is definitely the culprit. I don't actually have that much algae, just some brown on the leaves (which I manually rub off gently) and the odd bit of green on the walls which I scrape off, I was just being over zealous :facepalm: I tend to run the lights for a few hours...

Ok I am potentially a complete pleb - I wasn't doing the nitrate test right - I was shaking the test tube for 30 secs rather than bottle number 2 :/ :/ I did a comparison against the tap water seeing as I just did a 50% water change and the tap water nitrates are quite high but the colour is...

I put in API algae prevention which removes phosphates. I have quite a lot of plants so maybe they yummed up the remaining nitrates, and the ammonia>nitrite bacteria went on strike cos of no phosphates? So confusing! Just doing 50% water change now and hoping for the best!

Thank you! I think you're right, I think removing phosphates has upset those lil bacteria guys. No water changes done as yet. pretty sure I'm doing the test properly as previously was getting readings 10-20ppm. Also the ammonia now not really dropping is a bit weird as before was dropping to...

Ok so my fishless cycle was going well........I was dosing about 3ppm ammonia regularly and it was dropping to zero within about 12-24 hours. Nitrites were off the chart. Then all of a sudden nitrites were zero but whereas before I was seeing about 10-20ppm of nitrates these were also zero. Now...
