Vodka dosing.. HELP!

[dynamite]

I've been dosing vodka and Microbakter 7 for 4 weeks.. I started with 0.5ml in the first week then went up to 1ml in the second week and when I got to 2ml I started seeing this white film on the glass.. So I cut my dosing to 1.5ml.
I keep getting the white film and I don't know if I should cut my dose again.

My phosphates are 0.03 (Hanna Phosphate Checker) and my Nitrates around 20-25.

Before I started dosing vodka I had them around 30/40ppm
I never had Nitrates soo high before. I used to have them at 0ppm.
I went to FL for a month (It's been like 8 months) and then to Peru (6 months ago) and my neighbour took good care of my fish, he top-off the 1st two weeks with RO/DI and the other two weeks with tap water and he probably overfeed the fish.
I came back to an amazonas and diatoms everywhere! I have no more hair algae but I'm still fighting with some diatoms on my sand bed.. I want to get my Nitrates back to 0! And I can't seem to get them under 20ppm

Any help would be greatly appreciated

Here is a dosing schedule. Maybe you should read/do it better. Pretty sure I didn't double up at the star of week 2, & it sounds like you did see a drop in No3... so at that point you should've stopped adding mooore??? The white film is a bacterial bloom. Use the Scale for 80 proof.

Thanks! I was following that schedule, I guess I should cut the dose to get rid of the bacterial bloom. I'll see what happens I'll start dosing 1ml.

Are you just using Vodka or are you also adding sugar and vinegar?

Only Vodka but I'm thinking of changing to Probidio, only Biotim and Bio Digest. I don't know if someone has any experience with the method

how many times a week are you doing water changes? Maybe start doing 25% weekly to manually export the nitrates.

I wouldnt start switching methods all of a sudden - may end up doing more harm than good. Cut back on the vodka dosing and check your ro/di to ensure TDS is at 0.
