Hi. I started my 40gal planted tank three months ago. Now Cycling ok, PH 7.0 ammonia 0, Nitrite 0, Nitrate 5ppm, CO2 injection. Three weeks ago added six neons and a week later six red eye tetras. Today testing water parameters, my PH jumped to 7.8 ! it has been 7.0 all the time ! even if small fishes, could the livestock addition be responsible ?
