Hikari Seaweed extreme

[elrohiras]

Hi all, spot of advise. I have been adding a small pinch of Hikari Seaweed Extreme with defrosted mysis as my daily feed for almost a year, mostly to get some veg in my tangs and other herbi/omni fish.
I have always struggled to keep phosphate levels down at 0.02 ish where I want them (currently up again to 0.08). I see the Hikari has 0.5% phosphorus.
I'm guessing this could be contributing, even though I'm currently dosing NoPox. I also give nori on odd occasion.

Any suggestions on a seaweed alternative that would not add phosphates to my system?

I think frozen food adds a lot more unnecessary phosphate, as more of it doesn't get eaten and goes into the water than with pellets, especially if you don't drain the frozen food before feeding. I think any organic food will add phosphates to the water, not sure you can get away from it.

I normally defrost and rinse it in RO water, I just noticed the Hikari Coralific Delight also contains phosphorus which I use weekly as well.

I would have thought pellets would have had more, being processed and all?..

I think phosphate levels is correlated with protein levels AFAIK, so higher protein foods should contain more phosphorus? But not really an expert in organic chemistry.

When you thaw your frozen foods, chuck it in a tea strainer and rinse it with some R/O water. The frozen foods contribute to a lot of Po4

Interesting read, thanks

So tested my phosphate with a salifert kit today and get 0?..
Red Sea pro still 0.08.
Who to believe?
Nitrates at 0.1

If your going to keep looking at your Po4 in that low area i find the Hanna ultra low range phosphorus checker is good value once you get a system worked out to do it right... HI 736.....this one http://hanna.co.za/shop/checker-hc-/checker-hc-checker/21/hi736-checker-hc-phosphorous-ulr

Phosphates up again, took the plunge today and got a second hand Bubble Magus mini 7 reactor and some Seachem Phosgaurd. Will set up later today, will probably remove chaeto from fuge to make cleaning easier if it works.
