hey there hennie hows it going?
i have an issue i thought you can help me out with.
see my tank is having a cyano problem...but its not the usual suspects.
What EXACTLY does cyno live on?
reason i'm asking is my 680lt tank and nano both have cyno issues during the last month or two...nothing major has changed except in the nano there may be a build up of phosphates as the chemi-pure elite has worn out and i noticed some algae growth on the glass...but ive replaced that with GFO and the algae has receded but the cyno still persists.
Now to throw a spanner into the works i dont believe that cyno is dependant on po4 as in my 680lt reef i know my po4 is zero because
1.ive tested it.
2.there is no pest algae at all gha etc
3.i dose lanthanum chloride and the fact that its dropping my alk so much as compared to when there was po4 indicates that my tank indeed has no po4...
so how important is the alk part?if i raise it enough(10 or how high exactly) should the cyno disappear or am i still missing the root cause of the cynao?namely what is it feeding on?
oh yes the only change in the 680lt reef is that ive increased the lighting a fraction....1-2mm aragonite/crushed coral mix on the substrate for the last four years but recently ive removed most of it and replaced with playsand....infact that is when i first noticed the cyano the next day...that was two months ago and i though by now it would have settled.so maybe silicates?but shouldnt gfo also absorb silicates?
what about if i start dosing bacteria...not seachem stability as it doesnt seem to be working but i mean stuff like prodibio or micro bakter 7 will this outcompete the cyano for food and how do i make conditions more favourable for these other bacteria instead of the cyano?
