It's of my opinion that Cyanobacteria never goes away until you've killed it with antibiotics. I've dealt with my fair share of the stuff when I was getting my 75gal underway. Fixed my lighting problem - cut down to 8hrs a day and added more natural 6500k lights. I do a 50% water change every week... have since the beginning. I cut my feedings down to once per day from twice a day. I also removed all of the BGA I could, manually.

At first this appeared to be working, but it eventually came back and started to take over the tank little by little. It got on the plants, all over my rocks, and on some parts of the sand.

The only thing that worked for me... and it got rid of it for good was BGA Remover.

It only took one dosing of this and BGA was gone forever within 2-3 days. Also, it's beneficial bacteria safe.

I had very similar experiences.

Thanks Kevin

I did a good cleaning tonight but not able to get it all.

I have actually been trying to find that product in Canada to avoid hassles at the border.

I too had issues with BGA comming back all the time (even with weekly 100% water changes and mid week 50% W/C) until I got my nitrates under 1 ppm; since then it has never come back. The scrubber does the trick (and helps with the phosphates but that substance does not seem as critical after running some tests with higher levels.)

Antibiotics worked for me. Be sure to use one for gram negative bacteria. Increasing water flow also helps to prevent cyanobacteria.

I just found a small spot of it in my tank on one of the rocks. May need to scale lighting back a smidge. Seems like it could be food settling in that spot on the rock though.

I ordered up the ultralife algae remover, and then I think I will add an air pump and bubler to stir things up a bit.

I'll let you know how it goes once I receive it.

Good luck! I think you'll be pleased with the results.
