I think it might have something to do with my black clownfish possibly laying eggs. someone let me know.

its strange though, there is one string with little baloons sticking straight up.

Cyno!

 

[twocute2b4u]

yes, that is definitely cyano

 

[danielll]

is this dangerous? i will probably let it run its course if it wont harm my coral/fish/nem

Edit: yeah i got some diatoms, i think i am getting bad water. whats a totally non invasive way to handle cyano?

 

[rbredding]

yeah.. get it out of there...



kill it.. kill it with FIRE... !

Water changes, siphon out at the end of the photoperiod every day, and get rid of more nutrients than you put in.

cyano, no doubt. In the words of Ron, KILL IT!

the only thing i can recommend is selling me your clown there... that will fix all my little clowns girlfriend issues... probably not yours, but as long as i am being selfish here...

The best thing to do is to increase your water changes(weekly 20%), encrease water flow to those areas, cut your feeding by 1/3, cut you light time to 6 hrs and manually remove it right before lights are out(use a turkey baster) new tanks usually have a round of it before the good bacteria has time to grow where it can handle the bioload, older tanks get it when we encrease the bioload and do not export it out of the tank.

not diatoms, this is cyanobacteria, which is more closely related to bacteria than algae... they require nutrients to grow, specifically phosphates and nitrates... after your tank is done cycling, you will have an abundance of nitrates caused by the nitrification of ammonia to nitrite and then nitrate.

Regular water changes can help. Just make sure you are not introducing more nitrates and phosphates into your newly made salt water by using RO/DI water in your mix.

You may also consider a means of export through a refugium, where you grow macro algae like cheatomorpha or caulerpa (the latter grows well, but can become a nuisance, so I don't recommend it) to compete with the nutrient loving cyano and other nuisance algae in your tank.

Do you have a protein skimmer? make sure it is fully functioning, because a poorly functioning skimmer can cause this as well... at least, it doesn't help the problem any.
