If it's not one thing it's another, I have been battling cyanobacteria for some time now, it has become a weekly routing to blow off all the rock with a turkey baster. I really didn't want to treat the tank with antibiotics to remove it, so I turned to Dr Tims products in hopes to get rid of this nasty infestation.
When I was at one of SFVR club meetings, Dr Tim was there giving a talk about aquarium test kits, but when the floor was open for questions it quickly turned to his products. A question was asked about cyano and he has a schedule of products that claim to get rid of this stuff. Another person in the audience spoke up and saying that it worked and he continues to have great success with it.
So a month and a half, two months later I contact Dr Tim(I know, I like to research and be sure before I jump in to anything) And because he doesn't allow anyone in his lab, I had meet him at a fast food restaurant where we sat in the parking lot discussing these products. And anytime I have the chance to bend the ear of an expert I take the opportunity, we talked about bacteria and it's many roles facets of life in and out of the aquarium. Very interesting to say the least.
Anyway, I bought an 8oz bottle of re-fresh and a 32oz bottle of Waste Away. Hoping that this will cure the cyano problem in the tank.
The schedule that he set for my 125 gallon is 3 separate doses 2 days apart of Re-Fresh at 2.6oz each, then 2 days later start with 1oz of Waste Away and if the tank doesn't cloud up 2 days later increase to 2oz, then 3oz and then 4oz. after that point set the dosing to 4oz a week from here on out.
The weekend before I started, I blew off all the cyano and this is what has grown back a week later. Dr Tim says to blow off as much cyano as possible before starting so I did so, only leaving 1 patch to see if it will erode away. I also took a pic of a patch of hair algae to see if it does anything to that.
This is the patch that I am going to leave:
Here's the patch of HA:
Here's a 10 day follow up. After making it through the 3 treatments of the re-fresh, and 3 treatments of waste away, here is a pic of the one patch of cyano that I left alone.
This is before treatment:
and this is 10 days into the treatment.
an obvious conclusion is that the cyano looks thicker and fuller than before and it appears to be pulling apart.
However what you don't see is that the places that I blew the cyano off of hasn't came back, this past weekend I would have been blowing patches like you see in the picture off from everywhere. and to be fair Dr Tim said that I should remove as much as I can before starting the treatment.
I'm hoping that progress continues because there are patches of cyano throughout the tank that I can't get to with a turkey baster, so hopefully in the long term it will all disappear.
So in conclusion it certainly appears that a dominant for of bacteria can starve out the food source for cyano. I will continue to update as I progress.
