Yer -,well I feel quite annoyed - I have tried a few Lfs but particularly liked this one as he really explains everything well to me and doesn't push anything and also tells me what I shouldn't have. I bought the test the same day as Cuc so he knew it was marine!  Trouble is as a newbie you don't know enough to question what they say is a phosphate test kit! - know now lol

@HK_Fuey - I bought the DD Phosphate test kit - my water tested between 0.052 and 0.117 on the P-P04 range (and 0.16 - 0.36) on their PO4 range.  That must have been where my previous kit reading of 0.25 came from, PO4.  I don't really understand what the difference is but the one we use is the 0.052 - 0.117?  So I need to try and get that down - will water changes help that as well as rinsing the frozen food?

@Adenium Phil - did the rowaphos reduce your levels?

We use PO4, so on this test kit you want to be in the 0-0.04 colour range.

Water changes will bring it down (see previous explanation re. bringing down Ammonia with large percentage changes).

RowaPhos will also reduce it (it's messy, but it works really well).  However, that's an expensive way to reduce it initially if you plan on a water change anyway.  Put the Rowa in after the water change, so it's starting work on the lowest level of Phosphate.

Although my algae and diatoms have reduced somewhat now the phosphate reading is still higher than I want and still reading 0.16 on the D and D kit. I wonder if this is why my gsp is sulking and not opening?
Tank been set up 4 weeks now, though it was a bit longer actually but filled it 5th March,  trying to hold off with the first water change to be honest another week or two if can but dp you think it's better to do one this weekend? Ammonia and nitrite still 0 and Nitrate steady at 10.

I think it'd be worth you starting a tank thread, so any issues specifically about your setup can be looked at in one place.  We'd be able to look at what size tank, sump, lights, etc. you have, any previous issues, etc. and start to form a picture.

High phosphate can irritate corals.  Would want to know other levels, lighting details (type, wattage, schedule, etc.), etc. to get into it.
