Would it make any difference that my tanks are around 81C right now? It being summer time and all.

If your tank was 81c right now, that being 19c below boiling point, I would not worry to much about your PO4 as you will be having boiled fish for supper tonight.

:lol:

Boil to 80 degrees centrigrade not F :wink:

LMAO, it too early, need coffee. Ya C not F DUHHHH

You could write a recipe for boiled Nemo

"Dont fall off the wagon Bruce, fish are our friends not supper"

:lol:

LMAO, I soo hate it when my friends joke about cooking my fish.:D

:wink:

Post up your heat tested PO4 results, will be interesting to see the difference.

Well, I heated the water till just started to see a couple boil/ let cool, about 4 hrs. The reading is off the chart. I would guess 6-7 judging by the shade increase from the last one on the test sheet.

Now, if heating it gives true PO4, why doesn't the directions call to heat it? I mean, if the kit is not accurate as described? Thought Salfert was one of the good brands.

Hiya

You may have over played it a bit, only let stand for 5 mins then test this is important.

In regards to why manufacturers do not advertise this fact, i have no clue, but one thing for sure is that when fauna release all their range of test kits you will have all info available to you on how to perform accurate tests
