Cannot get rid of cyano!

[RedCoralEdmonton]

Im not saying that your tank isnt healthy, only if you are having issues with cyano or any other nuissance algae, that the reason could be the way you culture bacteria to dry rock.....

Thanks for the advice guys. But wouldn't physically removing the cyano, remove the phosphates or neutriants causing it?

I've removed it like 5 times now and it always comes back 2-3 days later

Chemi clean!! Oh wait... I already said that.

Lol thanks. But I'm kind of keeping that as a last resort.

Cuz if I use a chemical to kill the cyano, wont it just release everything it's absorbed back into the water?

I tell everyone that while Marco rock is cheaper, you seriously cant fill your tank with fish for close to a year with large percentages. But this also has a double edge as Ive seen people put 75% marco/ 25% live and leave the tank empty for 6 months, which doesnt work either because you need the cycle to be created.... and after 6 months thinking it shoudl be populated and ready they have algae problems.....

So final note being, in my opinion, Marco rock is fine to save money, but you need to realise you will need to figure out that happy medium to create your cultures, without going over board and getting a bloom..... not for the inexperienced, or trigger happy consumer....

I over feed my tank and my phosphates are high because of it, which causes cyano outbreaks. So far in the past the thing that worked 100% for me to get rid of it is chemi clean. No ill effects from using it either.

I used to have very high nitrates and phosphates, and had cyano, hair algae, you name it.... That was over a year ago. But since using bio pellets along with MB7, have never had another cyano problem. And I added Marco rocks to my tank since then as well. From what I understand, MB7 adds beneficial bacteria to your tank which out competes the cyano.

Chemi clean is an antibacterial and will kill Cyanobacteria but will also kill good beneficial bacteria. Which can cause an imbalance in the tanks biofiltration and in severe cases cause tanks to crash. I like many others have had success using it and I would recommend this as a last resort. (just before you feel like pulling your hair out).

It will not release the nutrients back into your system it just breaks it down so it can be pulled by the skimmer as dead waste.

i havent read through all of this thread but i read that ro water still contains silicates
which are needed by the cyano to grow. id google what to do to remove silicates from your ro water. the product chemiclean mentioned above i have used and it is a great product removing the cyano and the grunge from glass and equipment also but you have to be prepared to do a large water change after. the skimmer will run way too wet (virtually unuseable) until you to the water change so and bubbler will be needed. just my 2 cents worth

I was sceptical using chemi clean. But after a loosing battle I took that route. Worked great. And has not been back.
Just be prepared for some water changes after. It took three wc before my skimmer was back to normal

Btw. Rowaphos removes silicates
