I have had my 5 gallon Fulval Spec filtered tank for 3 months now. Put the betta in 6 weeks ago. He's the only one in there.
It is a planted tank - fairly heavy planted.
I have been doing water change every 7 days... but this time waited 10 days, tested water, and my results are
a little more than 5 nitrate.
I've been dosing Flourish, Flourish Trace once a week at half strength.
The numbers are very steady. The water is crystal, crystal clear. The plants are growing well.
I feed the betta individual pellets one at a time, being sure he eats them before I give another. Every few days, I give frozen (thawed) blood worms, brine shrimp a bit at a time to be sure he eats it all.
I was doing 40% water change every week - but after seeing nothing change in 10 days--- ???
Do I need to water change this often?
How do I know when to water change .... when the nitrates climb up to, say, 20 ppm? 10 ppm?
I am wondering if with all the plants, the good filter of the fluval and only one fish if I might do more harm than good doing a water change each week, just because it's been 7 days.
Being the only fish in there I am afraid that he's not producing enough waste to keep it cycled. I was dosing a bit of ammonia every day till I put him in there.
