Hello all,

I need some help figuring out a plan based on my system for finally getting rid of brown diatoms.

My current system is up and running with no issues whatsoever for a few months now and everything inside the tank has gone through QT. (I don't currently have any snails as I currently use the QT tank for something else at the moment but I am planning to set up a new one very soon but the snails will be added to DT after 80 days)

Setup:

180L Rimless tank 90cm x 45cm x 45
No light
Oase biomaster filter with heater (Almost 2L of Matrix bio media, one bag of carbon and one bag of GFO. The pre filter sponges are cleaned every 3 days)
Tunze macroalgae reactor with chaeto.
Dry rock and dry sand
2 clownfish
1 cleaner shrimp
1 Sand sifting starfish (was added 2 days ago)

Ammonia 0
Nitrite 0
Nitrate 0
Ph 7.7 (Salifert kit and was slightly towards 8)

Note: Set up is inspired by MikeyMikeMike

The tank was cycled using TurboStart 900 and feeding the bacteria with pharmaceutical grade ammonia (dosage and method was specific from a reefing article).

For the first month everything was still white and not a single spot of algae as the macroalgae was doing great and I was dosing weekly microbacter clean thinking that the good bacteria will colonise the rocks first and won't allow diatoms to catch on and therefore skip the ugly stage.
I would like to add that I don't actually know if that method worked as I didn't get another bottle when the first one was finished so that I can continue the treatment.

Current thoughts

I purchased a bottle of microbacter 7 and once I get it, I will start dosing.
Start growing a separate copepod population and dosing them to my tank.
Be patient lol

The images you see below are after the sand was cleaned using a vacuum and some parts of the rock that are white, I actually rubbed them with my finger to see how easily it comes off.
Also something very interesting, there are two spots that the brown diatoms turned green (images below)

Diatoms will normally go away on their own as the chemisty settles down.

MB7 is unlikely to make a difference in my experience, but is useful for biological diversity.

Your cat looks like mine.

I would say do nothing. Your situation looks normal.
