I've had a bad shoulder so my other half has been looking after our tanks, I've just done a test and my ammonia is 0.5 and nitrates are 40! We had some trouble with keeping the nitrates down a while back but got those down to about 20 with Amquel, I think my other has been doing the nitrate test wrong as he's been telling me it's 0-5, I should of thought it was wrong and tested myself. Now I'm back to with high nitrates and ammonia, whats the best thing to do now? Start using the Amquel again or try daily water changes? I don't really like using lots of chemicals. I have 4 leapord frogs and a peppermint in there that I'm worrying about. Hope someone can help. Thanks
