33 Gallon Reef

[Sidius]

You are likely right (same thing another experienced reefing friend recently told me). It was just an observation as it seemed to happen almost over night after removing the chaeto. I've done an extra water change this week to bring them back down to 10ppm now (I typically do a 4 gallon change every Sunday). I'm testing every other day with Salifert test kits purchased from J&L about 6 months ago.

What prompted me to start testing was basically within a day or two of removing the chaeto, I had a green film algae growing on all my glass to the point I was having to scrape it a couple times per day (I'm pretty anal about clean glass but it was very noticeable). Prior to that I hadn't had to scrape the glass in weeks. It very likely was be caused by a trochus snail that died and it was just a coincidence. I'm still trying to get an accurate count. I will remember the tip about the Alkalinity usage. I have just ordered a Red Sea Reef Foundation test kit and will track that as well.
