Are my Nitrates too high
Hi there, just a quick question.
Last weekend I did a 'spring clean' of my planted tank (trimmed some plants, vacummed around the substrate and in-between roots, cleaned the filter and media etc).
I cleaned the filter using the water that I removed from the tank in order not to kill all my bacteria.
I did a 50% water change, and generally gave it a tidy up.
Just now I decided to test the water prams to see how things were looking and I got the following results:
ph - 7.6 (has been this since day 1)
High Range ph - 8
Ammonia - 0.25
No2 - 0 ppm
No3 - can't quite work out the colour/number (somewhere between red and purple - so between 40 and 80ppm) - so lets call it 60ppm
This is much higher that I usually get - generally it's around 20/30ppm.
Is this expected after doing quite a major clean up, and big water change? Have I done something major wrong, and killed the filter bacteria?
Should I be worried and do a 25% water change now, and also tomorrow - or is it nothing to worry about and it will decrease back to normal in a few days time.
edit: my tank details if this helps:
Tank - Aqua One Eurostyle bow front 80
Dims - width 42cms, length 80cms, height 64cms
Volume - 185L
Lighting - 2 x 24w T5
Filtration - Advance 750
