Hello.
I've been running my ATS for about a month and a half. I'm starting to get a nice layer of turf in the middle on both sides (where the light is most intense). I'm sure if I did more with the light intensity and distribution it would have more turf throughout. An odd occurrence that I've noticed is some bubbles building up and almost creating a bit of foam. When I rub it off it looks like little peices of cyano. It grows in the areas of less intense light and after I rub it off it will build up again in no less than 1-2 days. I have a very high flow rate for my scrubber (35-40 gph) so I'd be surprised if it was cyano since cyano prefers low flow areas. Any ideas what I've got growing? Is it a good/bad sign??
In all my nutrient levels have been well maintained. In fact when I started my ATS I was using carbon dosing to manage nutrients but it seemed to be too touchy and the corals often seemed stressed. I started the ATS one day, stopped the carbon dosing the same, and my nitrate and phosphate levels are still quite low yet the corals are now thriving and don't look stressed from the aggressive and (sort of) unnatural means of nutrient removal that the carbon dosing was creating.
I'm building a 420 DT set up and already have my ATS set up to start cycling the rock as soon as it arrives so I'm hoping someone can help me with my odd bubble/foam build up.
Thanks.
