Wish i had the ability for both lol. Thats on my to get list, is the rest of the test kits, currently just have the beginner api kit. But soon, cuz i wanna get some corals in the tank by the end of the summerphosphates could be an issue which might cause some algae problems. I'd test for them and see where you're at.
You can always run some GFO to clean them out.
