question po about sa waterchange after cycle.
eto po ung huling test ko (April 21, 2014)
PH - 8.2
Amonia - 0.0 ppm
Nitrite - 0.0 ppm
Nitrate - 160 ppm
Last sunday po nag test ulit ako ng parameters and here are the results. (April 27, 2014)
Ph - 8.2
Amonia - 0
Nitrite - 0
Nitrate - 160
After a 20% waterchange nagtest ako ng parameters kahapon. I used RO water po and tested for the same parameters all results were 0.
Nagtataka po ako kasi nagtest ako kagabi at same results pa rin po nung April 27 test. 160 pa rin and nitrates. ano po kaya ibig sabihin nito?
BTW, nung nag water change po ako, nilinis ko na rin ung front and side glass ng tank ko sa loob to remove diatoms (Used rubber scraper kaya naiangat ko to palabas ng tank di po nahalo sa current water ko), rearranged some rock (ung ibabaw lng wala po akong ginalaw na rock na nasa bottom or naka contact sa sand.
note din po na naglagay na ko ng Livestocks few days before mag water change. (april 24 to be exact)
