Changed Substrate. Ammonia rising, what to do?
I finally change substrate from gravel to blasting sand last night.
I checked ammonia last night, neg. This morning, neg. This evening 0.25ppm.
I have 2 HOB filters that were fully cycled and kept running after the change.
I used Tetra Safe Start Plus (The small bottle that says it treats 20 gallons).
The fauna does not seem stressed yet.
I am hesitant to change water due to using the safe start. I will check everything again in the morning.
Is this normal? When do I get worried?
I have purigen in both HOBs (has been there for awhile). I have Prime, but I read that it is not recommended to use along with SafeStart.
