New to salt water

[S8oxl]

Good morning all

I'm new to the marine world, I got a aqua one about a year ago.
The setup is a follows below

195 l
Live rock
Marine sand
EcoTech vectors S1 return pump
EcoTech Radion light
EcoTech Vortech
Quantum nyos skimmer

Water readings

Saline :- 0.24 / 30
PH :- 1.0

I have no coral just fish sorry if I get names wrong !

Yellow tang
Blue tang
Puffer
Clown fish
Gobi
Queen empress fish
Pajarma fish
2 shrimp
1 blood scrimp
2 turbo snails
1 hermit crab
1 snail with long tounge
1 like lizard fish skins sand

I do a 25 ltr water change every 7 days
I feed them frozen cube 1 a day
Problem is I have the brown Algie I cannot remove and tank gets dirty so fast !

Any ideas welcome

Thank you

Suggest you research tangs in small tanks because I believe your way overcrowded for that sized tank. Also, water parameters are essential when looking for assistance. Good luck.

You need to know what your Nitrate and Phosphate levels are. Likely an excess. Then you need export them faster than the algae can use them for growth.

195 liters, as in 50 gallons?

If so, get rid of the two tangs. Get rid of the puffer too, unless it's a dwarf/toby. I don't know what a queen empress fish is, but if it's a queen angel, get rid of that too.

That would certainly help the algae problem.
