Dinos?

[Shua71]

I would like some opinions on this algae. So about 3 weeks ago, I downsized my very neglected 75 into a 25. I used rock from the 75 and bioballs as well from the sump. The 75 was bare bottom so I added some new pink Fiji sand. The 75 definitely had red cyano but not Dino’s.

About a week ago, I began noticing brown algae and thought they were diatoms. Now I’m starting to notice they are stringy and bubly. I do have red cyano still. I assume the brown stuff are dunks but looking for another opinion. I tested my phosphate and they’re at 0.4, so extremely high.

I’m prepping to do a water change now. Haven’t been able to do one as I broke a RO filter housing when swapping out the filters. Bought a replacement off amazon and of course they sent me a cracked one. Please let me know any suggestions. Thank you

Just based on the physical appearance I would say it's dino BUT a microscopic exam is needed to determine for sure, and what type.

What are your nitrates?

Once you get your RO filters. I would vacuum the sand bed.

What does your CUC look like?

I will have to test nitrates. Just did a 5 gallon WC yesterday after getting the RO up.

I don’t really have a clean up crew yet. Got a large electric blue hermit and 3 nassarius snails. I’ve read that inverts are very sensitive to Dino’s and they can potentially kill them? If you have suggestions let me know.
