Flushed the plants and got rid of the stock drainage attachments.

I noticed several small bugs crawling over the surface of the soil after i had flushed the soil. I can try to get a picture but they are about the size of a pin head and remind me of seed ticks. I cannot give more details at the moment due to lack of a magnifying glass or eagle eyes.

Any idea what this bug may be and how it will affect the plant? Any safe way to eradicate them?
