What would you consider to be high phosphates?
Curious as mine seems to be hanging around 0.1+. I have no corals as yet, at least nothing i bought but there LR hitchhikers.

Phosphate levels should always be as low as possible, below 1ppm for reef tank.
Tap water, fish food, medications, infrequent water changes are all factors that could cause phosphate to rise.

My tanks nearly done cycling and I'm doing abt 20% water change a week buut my phosphates are staying at 0.1. Is this a cause to worry abt?
