but it's only been a little over 5 weeks so I probably just have to wait. Actually I'm having trouble with the pH recently. I keep doing 20% water changes and keep adding pH Up but the pH keeps dropping to 6.0! Our tap water is like 7.4 so I don't know what's going on. I read that established tanks get acidic naturally but since I have 0 nitrites and 0 nitrates I don't know what's going on. Luckily the fish are ok (2 comets, 2 paradise).
I'm picking up on the pH issue.
The pH is linked to the hardness of the source water. Carbonate hardness (expressed as KH) acts as a buffer to maintain a stable pH. The higher the KH the more it will buffer the pH to prevent changes.
Chemical pH adjusters may work temporarily, but then the KH reverts the pH back, and the result is fluctuating pH which is serious with fish in the tank. [Don't know if you do or don't have fish in this tank that is cycling, but if you do please do not use the pH adjuster.]
Other things can also affect pH, and yes, it will normally lower in an aquarium with fish and biological processes. The extent (how much and how fast) somewhat depends on the KH as well as the fish, bacteria, plants, and water volume. There is quite an involved biological process occurring in an aquarium.
If you can give us the GH (general hardness) and KH of your tap water we can probably provide a bit more. Rather than spending money for a hardness kit, contact your water supply people; many have websites with the water analysis posted, and hardness should be included.
