How long has your tank been set up? Is this the first algae to appear?

The tank has been set up for about two months, the first algae was on the glass, now its on my sand and rocks, I havent done anything to combat it exept watch my nutrient levels.

That’s what I was thinking, probably diatoms. But phosphate is really low, wanted to rule out dinos

is it an issue, and will they go away?

Ya , diatoms are usually the first to show up and usually subside with out intervention when the silicates the feed on are depleted. Copepods can help speed it up. You are dangerously close to bottomed out phosphates which will invite dinos. Get nitrates up to 10-15 and phosphates up to.05-.1

 

[kevgib67]

Welcome diatoms, your tank is maturing and moving forward. Over the next year to a year and a half you’ll get the nastier algae, we all did and you’ll get through it. Thats is why it is called the ugly stage. Many many threads on here on how to deal with each type of algae you’ll encounter.

okay thankyou, so should i do waterchanges once my nitrates are at like 20? to keep it in range

Ya, that will help keep it below 20.
