high phosphatres

[JCnflies]

hi guys and thx in advance for your help.

Two days ago my phosphates were 0.5 and now, after a day of phosban, they are at 0.3. Other than a water change, is there anything I can do to decrease PO4?

Also, I think one of the reasons I got the high phos rate is that my RODI filters needed changing. Are ther any other possible causes I should be aware of?

what do you feed your fish?

 

[JCnflies]

too much, I guess NLS, mysis, occassional spirulina/brine bloodworm (my mandarin devours it), live baby brine 2x weekly, seaweed once a week or so. probably more NLS than anything else.

one thing i realized i did wrong was, after my corals started to die, i continued to feed at the same levels. I should have cut back.

I forgot, frozen rotifers, too

Do you use a phosban reactor? They are cheap and work well.

 

[JCnflies]

no, but do they take up muchroom? I have very little room left under the stand.

I tested the water again today and the phosphates are between 1 and 2 Hopefully when I check tomorrow, they will be between 0 and 1 - or even less!

Now to get the nitrates down under 10

phosban reactor takes up very little room. It's only about 3" wide, about a foot tall.

I'll check them out, thx Is there one you recommend?

It is called a phosban reactor. They cost like 40 bucks at aquahut and you need to get a small pump. It can hang on the back of your sump or it can be mounted somewhere else.

 

[JCnflies]

cool - I will check it out I am guessing that they are great at controlling phosphates

The do work very well but be sure to follow the direction carefully when adding the Phosban- it must be rinsed! Also get the correct sized pump & don't overpower it. The 2 little Fishies brand phosban reactor is available many places, including online and most folks run it using a Maxijet 400 PH.
Good luck with it!!

If you get a small valve you can put it on the exit of the pump, before the reactor and control the flow very well.
