Dinos under microscope?

Dreams92 · Mar 7, 2021

Posting a few pictures to see if anyone can help ID these. Would be greatly appreciated.

The first pic with the single dino looks like a prorocentrum type dino...very toxic variety, so run carbon when attempting to clear them out.

The other pics are difficult to see clearly since the dinos are turned slightly.

Agree with Idoc but treating amphidinium and prorocentrum is essentially the same(except for the toxicity of prorocentrum). Keeping nutrients up, dosing silicates for a competing diatom bloom, dosing phyto/pods when possible.

Thanks for the help folks. Either of you have a link handy for the method? I only ask because I have seen about 1001 different ways people say they treat this.

Alright today trying to take a few better pictures just to be on the safe side. Any feedback welcome. Also got a video with some movement.

I'm not certain but I would lean towards prorocentrum. Treatment for them and amphidinium is identical although you might need to run GAC with prorocentrum as they are toxic. LC amphidinium are not.

I appreciate that! Do you have a particular thread for treatment?

I'm sure it's on the big dino thread in several places but it's pretty easy to summarize. Dose silicates (water glass or something like Sponge Excel) to produce a competing diatom bloom. Keep nutrients elevated with NO3 in the 5-10 range and PO4 in the 0.06-0.12 range. Dose phyto and pods to help compete against them. Additionally some people use H2O2 at 1ml/10 gallons of display volume once a day. I have not done that as I have large colonies of zoas and they in particular seem to dislike peroxide.

Prorocentrum and amphidinium are usually not an easy/fast fix. It takes time to get rid of them. UV is not effective with them and is not recommended.

Thank you!
