Hi Guys,

I boiled and soaked my Mopani wood for 2 Weeks!

I'm doing a fishless cycle but the tank is getting really brown with tannins.

Since there are no fish WC are not necessary unless a result us too high.

But is too much tannins bad fir the cycle?

Thank you,
From newbie Patricia

Not in my experience, guess some things leaching out of wood could by affecting pH drastically.

Should I test for pH more frequently? For example when I test for ammonia?

It really isn't necessary to test the pH all that often. As long as the fish are slowly acclimated to your water and the pH remains stable, most fish are fine with just about any pH.

You'll need to test the pH of the water. If the water is too acidic the bacteria slow down or stop. This can cause a pause in your cycle. A water change and redosing with ammonia up to 4ppm would probably be a good idea.
 
I would test the pH but likely it is still in a suitable range, unless your tap water is very acidic to begin with.

How much of a water change? 50% or more?

Test the pH. looks to me like 6.8 or 7.0
