MarinePure and Dinos

[Shua71]

Has anybody had experience with marinepure causing Dino’s?

I transferred all my livestock from my old 75 gallon with sump to a 25 IM Lagoon. I used live rock from the 75 and also took the marine pure and loaded up the rear chambers with them to get more bacteria. I added dry Fiji pink sand. About 3 weeks in, I started experiencing cyano and Dino’s. I shut off my tank lights for several days and the Dino’s disappeared.

They’ve since come back about two weeks later. I’m waiting for a nitrate test kit to come in to test nitrates. My phosphates were at 0.3 when I first transferred everything over. They’re now at 0.1.

I know the nitrate test kit is probably going to tell me but has anybody had marinepure cause Dino’s?

I assume you have dinoflagellates on the substrate? Or are they also on your rocks?

In my experience new dry substrate is often overgrown with diatoms and/or dinoflagellates a few weeks after being added. It's something I was observing many times over the past years but it never grew out of proportions so dinoflagellates stayed on the substrate and after a few weeks it passed on its own. I consider it a small "ugly phase" of new dry substrate

The MarinePure was in the same system as the LR? If that's the case it would be difficult and purely speculative to say that it contributed.
Posting a microscopic image to ID the exact dino type would help in identifying interventions that are specific to the type.

It’s all over the tank. Sand rocks glass corals

I’ve had the diatoms for several weeks now

Thanks for the response. Yes the marinepure and rock were all from the 75. Both were 5+ years old.

With the description I believe it is Ostreopsis

If you have a microscope and can provide some images I will be able to help you with the identification.
