Start it again, wash that sand in a water from aquarium? Od should i throw IT away and pit there some siporax or something different?
Do you have aby advices?

That's a nice looking dsb. That dark color is doing a lot of processing. What are your hopes for this tank? Is that a refugium? Do you hope to still run one?
You will get a lot of different perspectives on this. Some will say throw it away and start over I'm going to say keep it and just clean it up. Just the algae. But for now, don't disturb the Deep part of that bed.
Is the rest of your tank still running with coral and fish?

There is a TON of DSB information on Wet Web Media

Seven pages of FAQ on the subject there as well. Bob Fenner and company do a good job of answering questions.
