Hi and Welcome to 3reef.

What test kit are you using?
How much are you feeding?
Do the fish look stressed?

Did you move this tank or was it set up as new?
Have you performed any water changes?
Have you used any Prime?
What is your water source?

How long have the fish been in the tank?

The tank is still pretty young so an algae bloom is not unheard of.

 

What test kits are you using? Some brands are better than others.

 

My Test Kit is Aip
my water is ROID that i make at home
i feed once a day frozon Food (PE Mysis) i wash in rodi before putting in my tank
and ever other day i feed Prime Reef Flakes at night
its a new tank started it with tap water with chlorine remover couldnt make the much ro water at the time .. i have did a 50% water change with rodi and all i use now is ro water
I do have 3 bags of
Chemi-Pure in the sump
not using any prime or anything like that
i add the clowns first the i added a fish ever 2 weeks after

 

I would double check that result against another kit, perhaps have the local fish store check an ammonia level. API test kits are really unreliable, you see a lot of error with the ammonia portion and reading .25 ppm.

Next I would proceed with small water changes over the course of a couple days.

Buy some Prime so you have it.

Buy some Microbacter7 or similar product like Dr.Tims and add per instruction.

When you get a chance to put up an image please do. We'll be more able to discern what type of algae issue you're having.

What type of snails do you have now?

 

I've had inaccurate readings from API. Salifert is a much better test.

 

Here is a few pics of my Tank

 

Can you get a closeup of the algae that's the problem?

 

Thanks for providing the images.

You have a nice bloom of Cyanobacteria going on. Possibly related to both low flow and the age of the tank.

With respect to the size of your tank you have little rock. Although I like a minimalist look you need to make up for the deficiency in biological filter somewhere else.

Definitely add more flow, those powerheads are not going to cut it.

Try to add more rock either to the sump or the display.

These problems will work out at the tank ages. Cyanbacteria can be a chronic issue if you do not intervene.

 

I definately agree with flow. Both power heads are ponting against each other at the moment. Add a couple more to get the water moving all over the place. For now you may want to move those two power heads to the middle and point them towards the front glass to create more of a convection style current until you can get more power heads.
