Most probably diatomic brown algae. Often occurs in new tank setups. Otos eat it.

Having an algae crew is fine for keeping new algae growth under control but most of the work should be done by you. You need to go in and work on the algae, do a large water change right after and address the real cause of it. Addressing the real cause of the algae is the long term goal unless you like them. Give plants what they want to grow and you would have less or no issues with algae.

I don't think SAE will eat these brown algae.

last night cleaned the glass and did a 10% water change. IS it alright do larger water change 30%, worried it might upset the good bacterial trying to establish itself.

current the light total is 182w only- x 2 54w 5ft FL and x2 37w 4ft FL

now the algae crew is only the 12 mollies.

Forms in soft brown clumpy patches. In the freshwater aquarium, these are usually diatoms. Usually indicates a lack of light or an excess of silicates. Increased light levels will usually make it disappear. Easily removed by wiping the glass or siphon vacuuming the affected area.

that means i need to increase the light - 2-3w per gallon=3.2L

Some of the brown algae also grows on the interior of the inlet and outlet pipes of my ehiem ext. canister. Whenever I change the filter media, I'll have to stop the pump. After switching on the pump again, the force of the water somehow dislodge some of the brown algae and drives them into the main water column. My SAEs are most glad to eat them though...

Those are not brown algae. Those are slime consisting of bacteria.
