Tank restart - Dinoflagellates

[Andeyking]

After increasing nutrients and having a large alkalinity swing the already stressed sps have STN'd so a restart is going ahead.

Whats the best way of doing this?
I was thinking of taking out all the rock and sand and discarding, then filling the water that was displaced by the rock with household bleach and running the tank empty with just bleach for a few days in an attempt to kill any remaining dinos.

How would you go about this?

I'm not opposed to doing whatever seems to make sense, but considering only what you posted: why restart?

A restart does absolutely nothing vs dino's nor will it prevent an alk swing.

As long as you nipped the source of both of those problems in the bud, you should just take the tank forward, IMO.

Do you know what provoked your dino problem?

Do you know what caused the alk spike?

Will either cause happen again?

Unless you're answering the wrong way on those questions, there's no good reason to put extra effort into moving forward. Simply don't make the same mistakes again.

And if you don't know what caused some or all of the things that happened.....then let's figure it out!

A restart will hopefully prevent a dino bloom which is what I aim to achieve.

Your supposed method of elevating nutrients has done nothing in slowing down the dinos. I have bubbles forming on green algae.

Do you know what provoked your dino problem?
Overdosed on carbon, stripped a young tank. Fresh rock started with colony.

Do you know what caused the alk spike?
Elevated nutrients slowed the uptake of alkalinity down drastically.

Will either cause happen again?
I no longer plan on using carbon as nutrient export. Chaeto will be used once the tank has matured for at least a couple of months to establish a good bacterial colony.
