First off thanks for all the great advice on this forum. I have been lurking for 2 months now learning as much as possible to get my first tank set up.
So I have now had my tank 2 months, a 70l Jewel Rekord 700. I managed to complete a fishless cycle in about 4 weeks and have been adding fish over the last 4 weeks. I first put in 7 Neon tetra and 2 cory catfish. I waited 2 weeks and then added 4 guppies.
I have been using the api master test kit to check my levels and so far everything is going well; PH 7.6, Ammonia 0, Nitrites 0 and Nitrates 20 (I think!!).
My question is; how often should I be doing water changes (so much conflicting advise). I have put in a relatively large piece of bog wood and my water looks like tea. I did soak it for a month but it is still leaching tannin. I understand that it can help with PH and soften the water however I had hoped the water would now be clearing up. So should I take to wood out or just wait and let the filter do its thing?
