[Tab28]

Are there any obvious symptoms in corals from a high potassium level?

It can cause burned tips similar to fluctuations in alk and a severe overdose can cause RTN. Additionally, yellow SPS is said to get a greenish hue as the Potassium levels rise.. There are a few Potassium test kits available... I know Elos & Red Sea Pro make test kits off of the top of my head. Your should aim for a potassium level around 380. HTH
