How often are you feeding the fish? And what are you feeding?

 

How often are you doing waterchanges?

 

Phos reactor, i wouldn't use one personally. Your phos is at 0.04, any lower and you can have even bigger problems.

 

Are you using any media that reduces nitrates? 

 

 

If reducing frequency/size of waterchanges and increasing feedings doesn't raise nitrates then dosing nitrates is the next step

hi i am feeding every other day, 2 frozen cubes shrimps... mixed in Red sea A/B then syringed  into the corals..when defrosted 

i did add cheato  a few weeks ago and removed it today.

water changes i was doing 50ltr every 2 weeks.. 

phosphate reactor has about half a cup in it and changed every 2 weeks  ( phosguard  )

i think the cheato was sucking all the nitrates out..

 

how do you remove your phosphate's

should i turn off the skimmer..

should i remover the filter sock for the time being

You need phosphates and nitrates. 

 

Phosguard and other phos reducing media should only be used as needed.

 

A sterile tank devoid of nutrients and algae is not healthy.

 

Red sea ab + is supposed to be dosed into the tank directly in high flow not syringed into the corals.

 

The filter sock just removes particles not really nutrients.

hi should i turn off the phosphate reactor,  even tho its at 0.04.. 

should i  leave the skimmer off totally and let the nitrates build up

how do i control the phosphates and nitrates.

i will stop direct feeding the corals today..
