Cyano suggestions

[Reef Altitude]

Hey everyone,

I am having some cyano for the last 4 to 5 weeks in the 200 gallon tank. It's around 9 months old now and has sand. Parameters are all stable and have been. Phosphates and nitrates are medium low but not zero. Coral all looks happy, lots of growth and polyps.


I do run a little more balanced spectrum and was not vacuuming the sand. We have nassarius snails and a dragon goby.

Looking for eco system style recommendations (don't just say Chemi clean or something ) and willing to take some time to get things balanced out.

I am dosing microbacter7 but not holding my breath haha.

I used Brightwell Razor and MB Clean a while ago to get rid of mine.

Water clarity and Cyano fix

This is a thread I came across on R2R Cleared this to make sure it was OK to link. I've found some threads on here that have involved the topic but this one gives the formula and how to for DIY "coral snow". Used as described it will clear your water and there is a cyano formula as well...

It seems like this works by reducing nutrient generating "stuff" suspended in the water and then coating things with bacteria slime to prevent cyano coming right back.

Because my nutrients are pretty medium low already would this drive then down further?

 

[billyocean]

The snow does nothing as far as nutrients or parameters..it just binds particulates. If you are worried about p04 or n03 some diy trisodium phosphate and sodium or calcium nitrate can be dosed. Or you can grab some pre-made Neophos and Neonitro for convenience

I'm dealing with a similar situation in my frag tank and I'm upping water changes and raising my nitrates (NO3). I used to use sodium nitrate but this time I'm using Neonitro. My goal is to get NO3 somewhere around 5. I've been dealing with it for a little while (not really doing anything about it) but I recently swapped out my frag racks and nice clean plastic frag racks are apparently a magnet for cyano to grow on for some reason.

It seems to love nice clean surfaces.

 

[billyocean]

The nasties love clean surfaces indeed!

One way to improve coralline is to dose magnesium. Coralline covering racks or whatever helps vanquish all of the unwanted stuff there. It takes a ton of mag to actually raise your mag but if you start dosing (depending on tank size) 30 ML a day for let's say a 100 gallon tank it will explode corraline growth and coral loves it. It won't effect your mag numbers either.

it seems most coral like no3 to be 15 to 20

I am now running my skimmer only 12hrs now to keep my nutrient from bottoming out. Still dosing neo nitro and now Phos (eye balled), when I think it need some. Lol.
