I have 3 weeks and loosing the battle against what it looks like Diatoms, Params are PO4=.07
NO3=4.6
I tried microbacter 7, Phytos, now in addition microbacter clean, pods (2bottles so far since they are expensive) will try another 2 bottles next week (and my Royal Gramma keeps eating them) cleaning socks every day since I have to much algae on them running and small UV reactor since I dont have enough resources to buy a bigger ice cap UV, I dont know if I should swipe the sand bed to help clear some of it its all over the sand bed really bad its forming bubbles but its not Dinos.
Here some pictures, please give me some advice before I try swiping the sand bed, since now its starting to move on rocks.

Diatoms will vanish on their own once excessive silicates are used up. The only thing you need to do is to make sure the water you use to top off evaporated water and to perform water changes is appropriately deionized. To verify this you need a TDS meter for pure water that should always read 0ppm TDS on freshly made RO/DI.

If your tank is just a few weeks old you are going to have a diatom outbreak which is the beginning of the so called "ugly phase" and expected. There isn't really anything you can do to prevent it and you will just have to sit it out.

New sand is often still very saturated with silicates and will leach silicates into the water for some time. With some patience it will get better eventually. Note that after the diatom phase you will get green hair algae and only after that algae is gone you will get coralline algae and the tank is ready for the first robust corals. It is possible to introduce corals early but this comes with a risk.
 
This is my third tank and I never had such big problem yes I do use RoDi I have the BRS 5 stage filter and I do have a TDS meter testing 0 I was fine for like a 2 months but it just break out really bad, please help me with some doubs I dont know if I should siphon or not? Just peel the layer of brown slime it concerns me the bubbles but I’m very shure they are not dynos, so should I peel the top layer??

I can't see much on that microscope recording. At 200x magnification it should be possible to differentiate diatoms and dinos based on movement speed and rough shape. 400x is better.

If it's diatoms they are pretty harmless and they usually create dust and very very short "hairs" by clustering together. Slime is rare for diatoms iirc

Manual removal is okay regardless of it being diatoms, dinos, chrysophytes, cyanos, or anything else. If it is so severe I would say dinos or chrysophytes.

Ok got peel the slime layer every how often should I do it or just the first time and then let the microbacter clean and pods do the trick?
If dinos or chrysophytes what should I do?

You can remove the layer as often as you want. If it's dinos it will grow back very fast.

For chrysophytes it would be the same as for diatoms: get rid of the silicate source and go from there.

You don't need to add any more pods if there is food available they will reproduce and keep a stable population as long as you don't have a dragonet in your tank or a pipefish.

Are your nutrient levels still above 0? If the problem is severe I would expect at least one nitrate or phosphate to bottom out.
