Dinoflagellates or diatoms? microscope ID

[Joe Timms]

Good afternoon.
Could anyone help me identify the bacteria in my reef tank?
I have a 180l aquarium which is filtrated with an external fluval fx6 canister filter. The tank is just shy of 5 months mature and is currently stocked with a pair of black ice snowflake clowns, 2 pyjama cardinalfish, a saffron coral goby and a cleaner shrimp.
For lighting I am using 2x AI Hydra52 led lights which are controlled via my phone using the AI director. Please find attached some pictures of the bacteria. My thoughts were first dinoflagellates due to it's stringy nature in the water current and its rapid spread in a young low nutrient tank. However I haven't seen dinoflagellates look like the bacteria I have photographed under the microscope. Any help will be much appreciated. Many thanks Joe.

Looks like diatoms to me.

Diatoms and ones that need attention in the way of maintenance and a clean up crew.
Start by blowing the surfaces loose with a turkey baster. Fllow up with a siphoning of loose matter and the diatom itself. Reduce white light intensity a little for about 4-6 days and add the following snails:

3-4 turbo snails
4 astrea snails
3 nassarius snails
4 trochus snails
3 cerith snails
6-8 blue leg Hermits

BEFORE DOING THE ABOVE, TEST YOUR PHOSPHATES AND NITRATES WHICH MAY BE ELEVATED.

ARE YOU USING TAP WATER FROM FAUCET OR RODI WATER ?

Its a porcelain Crab is common in many waters and has a flat, round body with two large front claws. These crabs have a pair of front arms called maxillipeds, which have ends that are feather-like in appearance. They use these appendages to filter the water for any passing food. They are peaceful and interesting invertebrates for the marine aquarium.
Porcelain Crabs live together in pairs typically found within or under rocks in nature. The ideal setting should have plenty of live rock for both hiding and feeding, and will not contain any fish or invertebrates that may bring harm as they are very peaceful invertebrates. They are reef safe, and will not harm other invertebrates or corals.
The Porcelain Crab constantly filters the water for planktonic food, but will also scavenge for larger meaty portions. Offer the crab small bits of fish, shrimp or meaty food,

Thank you for the identification

Amazing help! Thank you so much. Phosphates are 0 and nitrate is at 2 ppm, I'm sure there are phosphates but no doubt they're being sucked up by the diatoms. I am using RO, however my local shop are awaiting a new membrane so the water is reading a TDS of 38. Thank you again for your response.

I am having similar problems but mine does not look the same - I found this on Reefs(.)com and based on that article I think you do have diatoms.

Side note: I don't believe I have diatoms
