I'm curious, because the other day I turned the filter off for maintenance...
Today, I was looking at the aquarium... and everything was perfect. The fish were happy, snails (mts pond and ramshorn) were out and doing their thing, and tons of new plant growth since yesterday.
I tested the water, and everything was PERFECT. Even the PH was 7.5 with a KH of about 6.
The KH and PH have NEVER been that high! IT's a dream come true since I've been TRYING to make them go up for weeks and weeks. (months probably.)
Oddly, the filter was off. (Apparently I forgot toplug it in)
So, I'm pretty sure the bacteria is probably dead... Is it possible the filter was responsible for the stubbornly low ph?
Also... if the ammonia stays 0... can I just remove the filter altogether? Or only use it periodically to clear the water when neccesary?
