Dinos, Even with decent phosphate readings?

[Kyleovski]

I’ve been battling this for a while now, thought it was dinos but not so sure anymore.

Parms:
Phos: between 0.05 and 0.075 using Nyos test kit
Nitrate: 0.5ppm salifert

Any ID?

That could be cyano.
Many colors and I get the dark type from time to time.

Ye thought it was dinos and worked hard to get nutrients up but it’s not subsided unfortunately

Microscope will be the best bet.

Ye think that’s the next step, LFS suggested I bring a sample in so I’ll do that this week as they have a microscope

I'm not sure from the photos. It could be a cyano strain.

How did it start? Did the Nitrate and Phosphate sit at zero for a while?

Once Dino's arrive, raising nutrients will simply feed them, you need something to outcompete them.

When in doubt, it’s fairly easy and safe to use chemi-clean to rule that pest out.

Just make sure you skim, extra air stone is helpful.

Nitrate low in my thinking. I’d bump that to 5-10ppm, pest stuff loves low/no or imbalanced nutrients

Ye I bottomed out nutrients. So should I dose silicates or something to get diatoms?

I had Dinos in my 13g Evo tank for over 6 months.

Yes, the thing that seemed to finally defeat it was dosing Silicate and keeping nutrients above zero (but not high) - around 5ppm Nitrate and 0.1 Phosphate.

I also dosed MB7 so I can't say whether it was one or the other or both - or something else all together.

It still took over a month to clear them up.

In your case I'd confirm the problem with a microscope before potentially making things worse.
