Hello! I’m afraid you’re going to have to give us more information. How many gallons, how many koi, what kind of filtration, where do you live, “established” for how long.....? City or well water, what kind of plants....? Any other chemicals beside liquid barley?

Can you post a few pictures for us?

Eighteen inches is a little shallow for koi.

Welcome @bradcope88 , as @Mmathis stated we need more information. Could you post some pictures of the water in addition to the information she has requested?
