Yay! Today I will begin my journal of how I will battle a self induced Cyanobacteria outbreak in my reef tank.

First I'd like to say that i would not recommend attempting this without prior reefing skills. It can easily become more than one might want to handle.

So to induce this nasty slime I began to over feed and I left the lights on a couple extra hours a day, at 14 hours.
This quickly made the sand and rock grow red slime, thus the battle begins.

Today I began to take my first action.
My sump is in the basement and the display is on a cast iron stand capable of holding 2 90g tanks, so I have room to work with under the tank.

I cut the drain that ran from the 90 to the basement and stuck it to a drilled 20 gallon tall. I then added a new drain from the 90 to the 20, thus completing the water's route.

In the 20 there are no pumps and 30LBs of live rock. I lit the aquarium with a 150w metal halide that is 10,000k and probably old, is it was used. The good thing is old bulbs are a recipe for odd algaes. My goal is to essentially transform this "presump" into a cesspool of diatoms, hair algae, and Cyanobacteria. It is merely another form of Algae Turf Scrubbing.

Once I had the tank full and running I began to siphon all the nasty i possibly could into the 20 gallon and seed the stink so to speak. Or convenience I zip tied one end to the 20 and I just hang the hose on the stand for quick access during the battle.

Here is the beginning of my progress. The light is now on for 24 hours until it gets a good biofilm and I will move to 16hrs.

Here is how my tank looks right after I siphoned it clean:

This may or not work. Only time will tell. I am going to not take the display lights off of their normal schedule. I am going to rely solely on siphoning growth into the 20 until it establishes enough of a grasp to contain itself without maintenance.
Stay tuned for updates. This could get ugly!

This morning the sand is much less nasty than it was before.

The rock is also much more purple without the slime I let build up.

There is a bit of hair algae on the rocks, but since the slime covered it before I am hoping the fish will do their job and eat it while the 20g is building up its disgustingness.
I'm hoping to solve this issue without changing any of the water during the battle. I am trying to relocate it, not eradicate it. Which seems to be working because its making nice slime bubbles

very interesting concept and it does appear to be working. are you going to eventually take the 20 gallon back off line?

No it will be a permanent stink tank. I'm hoping it will keep the Cyanobacteria and algae in it at all times rather than appearing in my aquarium.

Cyanobacteria is responsible for the irradiation of most of the ancient oxygen intolerant beings before out atmosphere was breathable. I believe using it as a means of purification will benefit my tank more than any mechanical or chemical means. I hope to eventually be able to turn the skimmer off and sell it for some corals :)

Upgrade/downgrade!
Went to 2x 75w equivalent (meaning only 52 total watts of actual light) 6500k curly outdoor bulbs. Check out the upgraded wicker pendant!

And I ditched the frag rack and re-awuascaped for fun, I literally have not moved the rocks since I filled the tank up!

That's with the odd color dusk tubes. Looks like eggs to me.
The sand isn't doing to bad either.

Its gone from slime to brown diatom powder, so it seems to be slowly reversing!
I siphon what nastiness builds up if I'm just staring at the tank, always keep up if you have a plan. Persistence pays off, or so I hope.

The lights to the display are not on yet, so I will show the progress of the cyano scrubber.
The light change dramatically increased growth! The rocks went from brown to red overnight.

The light swap made my temp drop to 75! Guess its time to plug in the dusty old heater I haven't needed at all this year. Looking forward to a smaller electric bill for sure!

I Feed 3-6 cubes every other day or more just to make sure the tiny critters I may or may not have definitely get food and the ones that do get full and don't really mess with eachother or corals

The yellow light doesn't really capture the red very well but you get the point.

Basically the environment down here is working great! I might actually try a little more towards the red spectrum if this does not fully eradicate the stuff in the display.

An air bubbler may also be my next addition just as an experiment.
Oh and there's the damsel. Being a damsel.

Ok, I took a few days off to ignore the progress to see if It was really working. Water never boils when you stare at it right? Lol.
Check out the rock!
No crud on it, just new coraline growth!

I also changed the light a 3rd time to this 24 inch aqueon modular led with 1 white and 2 color max bulbs I had lying around (because its crap) but crap lighting seems to work best on algae!

And the cyano farm

The glass is almost completely covered with a film of green and red slime. I took out the scraper for the new biocube lol.

Current feelings of this approach;
Very pleased.
Maintenance is at an all time low, aside from top off and dosing.

My tang is growing into an adult now, so he is creating mass sprays of poo..this seems to be keeping up with that very well.
I have not stopped feeding at all either nor done a water change yet.
The water is very clear! The corals are all open. I even found a frag of black sun coral behind a rock that I swore was dead when I lost it months ago! It has actually regenerated from a skeleton to a skeleton with black dots sticking out of its branches. Maybe it will come back?
