![]() I don’t know what the percentage of rocks you have add from the total weights of your rockery and if you cleaned them or cycled them but…..
Yep! That might be just it. The introduction of dry rock to the system will cause the rise and build up of phosphate and nitrate (decomposing of dead animals in the rock into ammonia -> nitrite-> nitrate) The cyano just loves these conditions. |

![]() I believe you are right. I don't understand that if it is the case then why cyno appears on the old rocks in the tank, not just the new ones? The question is just for my learning experience.
I tested nitrate with Salifer, it is 0.5ppm. I guess it is the end of the cycle. The cyno should clear up soon. |

![]() Cyano loves Nitrates and posphates. It is usually allways in your tank. Just kept in check by the ecosystem ballance. Add something extra(the uncured liverock) and that c an throw the ballance over the edge. Same with changing the lights. Different PAR all of a suddden, can let it grow untill the ecosystem comes into ballance again

![]() The cyano will spread in your tank in places where the water flow will “allow” it to grow….

![]() Beside doing water change and clean up the cyno, I guess I just let the system balance out again.
My first impression was the since the ceramic biological filter created nitrate, I wanted to replace it with live rocks. And I always thought that my tank is now 5 months old, it should have enough "good" bacteria not to throw anything off balance even introducing new rocks. I was wrong. I have another question. I placed rubbles at the back of the Red Sea Max where the RSM skimmer used to be; however, there is not much water flow there (very little water flow), this is because I took out the orginal RSM skimmer replaced it with the Tunze. Lived rock but minimum water flow. Do you see anything problem with it? Nitrate issues (dead spot)? |

![]() Yup changed my bulbs 4 out of 6 and my sand is red. Did a lights out for 3 days and a
large water change, no food and covered with a blanket and now I am slowly working up to more light and food. Seems to have helped alot. Opps, won't do that again! Thanks Dan |

![]() It really bothers me because I was not updating lights, I just replaced old to new light causing an outbreak in the cyno. And my snails (astrea and trochus) do not eat the cyno.
It must be the lights that causing this outbreak. Now I am testing nitrate and phosphate. My nitrate is .5ppm and phophate is almost zero (they have always been low even I introduced the new lived rocks). So people change the bulbs. How do they avoid this outbreak? Cut back the light time...? |
