Hi everyone, a bit of background, I kept fish all the time I was growing up, years I had tanks running but then life got in the way but now I've settled down it was time to invest again.
I have a 120lt 90cm tank with an oversized internal filter box, the tank has been running approx 3 weeks, 1 week empty, 2 weeks with fish (6black neon tetras) I have 4 small plants (apologies but I know not what they are), 2 lumps of bogwood and 4 medium pebbles (off Brighton beach), everything was boiled for about an hour before placing.
I have approx 60% gravel and 40% sand ( I've always loved Julii corys so planned for them with the sand).
Now you have an idea of my tank I get to the confusing bit, nothing is happening, or it appears nothing is happening with the cycle, I added a bacteria booster when I added the fish and test the water twice a day (morning and evening) nothing is showing up, no ammonia, no nitrites and only slightly more nitrates than the base I get out of the tap. I've even bought 3 different testers to factor out getting a duff batch still no results whatsoever, not once.
Anybody have an idea what's going on? I'm at a loss and wondering if I should be concerned, any help anyone can give would be amazing.
