What kind of Dino?

[BonsaiDave]

Ostreopsis I think? Trying to raise nutrients but can’t seem to. Have nitrate and phos (neo) coming Thursday but otherwise just over feeding (nitrates still 0-1), and using reef roids (phos still zero).

Yep, they are almond shaped and spin around like a tether ball from the end with the white tip. They are the easiest ones to identify, most ugly in the tank and most toxic. We used a UV sterilizer plumbed directly into the DT at 1 watt per three gallons of water and carbon to remove the toxins. Took two weeks to eradicate them.

@SY2932 Thanks for confirming. This is a 25g lagoon AIO. Looks like there are a few options for UV, I'll take a look.
