Concered GHA, now for cyano.....

[flatreefer]

Hello

So I had a big bloom of GHA, I managed to get it under control by removing it by hand and controlling nutrients,

Now I have cyano.....

Initially I had thought that because my nitrate is at 2.5-5ppm and phosphate is 0-0.03ppm(can't tell with sailifert)
That I needed to dose some phosphate to get my tank balanced properly

So I have been dosing it and I have noticed just more algea on the glass and more cyano

Parameters
Salt 1.026
Alk 8.3dkh
Cal 425ppm
Mag 1320ppm

Nitrate 2.5-5
Phosphate 0-0.03ppm

Tank was set up on May 1st 2021 bare bottom

I wouldn’t worry about a little bit, here and there to be honest. Siphon it out.

IMPO you're doing just fine.

Don't sweat the uglies.

ESPECIALLY in a barebottom, you're tank is still establishing it's overall natural biofilter. This is gonna go on probably for the first 7 months to a year. You'll be "fighting" uglies.

Just keep doing what you're doing.

Re: the Cyano, suck it out and let it be.

IF it gets OUT OF CONTROL everywhere and is smothering corals.

Try these best brand IMO.


Your phosphates are probably high too.

Doing drastic things can make everything so much worse.

Do you think my Phosphates would be high and give me a 0- 0.03 pmm reading? I have chemi pure blue media bag I could throw in?

Also bought a hanna phosphate checker used, my dummy didn't realize that it was the high range one and all the reagents are expired so I can't use it at the moment lol

No sorry missed your readings.

IF that's the reading then that's the reading.

Normally cyano and high phosphates can be found at the same time though for sure. not a necessity.

Everyone gets a bit of Cyano from time to time, even if they never notice it.

Agree with the others here that algae is part of owning a tank. It’s mostly about control.
