i don't really have a problem with algae on the glass, that stuff i have to clean maybe once every 3-4 weeks. Im pretty sure that its cyano though. I have had the lights off for 48 hours as some have suggested. They said it helped them so i am trying it. It seems to be better but then again it doesn't need like to exist, just to turn green. We'll see here when i get the lights back on tomorrow or tuesday. thanks for all the help dudes! appreciate it.

IMHO you need to let all the cyano die off which usually tanks more then a couple of days.

After that initial "shock" treatment, then adjust the light and feeding so it stays away. Start with 1/2 of both then if cyano comes back reduce both, if cyano does not return increase both.

my .02

maintain Fw and marine system with a strong emphasis on balanced, stabilized system that as much as possible are self substaning.

have maintained FW systems for up to 9 years with descendants from original fish and marine aquariums for up to 8 years.

With no water changes, untreated tap water, inexpensive lighting by first starting the tank with live plants (FW) or macro algae( marine)

Let's be clear what you are actually dealing with. As I said in response to the video, the floating blob looks like cyano, but what is on the substrate may just be algae.

Cyhanobacteria is due solely to high organics. Blackouts and similar "fixes" willnot work long-term because until the source--the organics--are dealt with, cyano will return and return. But cyanol is the green/black slime.

Algae is very different. This is due to light and nutrients being out of balance for the plants. Algae will (or should) appear in any healthy aquarium. You cannot avoid it, or you will have an unhealthy tank for fish and plants. You simply keep it under control, and here the light (intensity and/or duration) and nutrient balance are the factors.

That's the reason I emphasize reduced lighting and feeding after the initial black out.

Seriously this has worked over 95% of the time on all my fw and marine tanks since the late '70's. And for many other people as well.

Most of whom were extremely surprised and initially thought "it couldn't be that simple".

What happens is you don't have the same environment after the initial blackout by changing the lighting and feeding. You rebalance the tank so the plants are in control again and the cyano stays away. For years and years.

Still just my .02

maintain Fw and marine system with a strong emphasis on balanced, stabilized system that as much as possible are self substaning.

have maintained FW systems for up to 9 years with descendants from original fish and marine aquariums for up to 8 years.

the stuff on the substrate is the same stuff on the plant, or at least thats how it looks to me. The way it peels off when i rub it between my fingers is the same as the stuff on the plant, they same color, same consistency. Trying the black out. Its been this way since fri. For you that have done the black out, how long did you go? I notice there are some small brownish clumps of what i assume is the cyano that is no longer photosynthesizing. I have been vac-ing frequently. tomorrow morning will be the next.

sure it will go away but will it come back, treating the problem is easy- solving it usually isn't as easy

Usually I notice improvement after the first day. And again usually almost totally cleared after 3-4 days with total clearing in a week.

But for stubborn cases I have had to go 2-3 weeks. In one case the tank was still dark green after 2 weeks. Then in a couple of days it was totally clear.

My current 55g on the porch gets 3-4 hours of almost direct sunlight as the only light. It took almost 2 months to clear up but that is the "outlyer". I also had to (obviously) cover the tank. the other tanks I just killed the lights.

Went to the LFS where i got my dwarf sag and glosso today...first time back since i got the glosso...Guess what! They have Cyano in 5 tanks including one that i got my plants from...I bet it piggy backed its way on my plants...I am about 99% sure thats how i got it bc my nitrates never dropped that low for any period of time. My tap water has trace amounts of ammonia, which gets converted to nitrates within a few hours.
