My PO4 allways .005 or less. Most times, I can not detect it with the Salfert kit.

In regards to the fish not being affected by high PO4 you are 100% right they will show no real sign of stress although it can lead to a general weakness of teh immune system as the fish are kept in conditions that are not native to them, nitrate in high levels will also cause gill deformaties.
The biggest issue for fish only systems is tank appearance, algal blooms Cyano, to name just two. Drop me an email at sales@aqua-digital.com and we can go from there. Dan - do a heat test on the PO4 then see the results, it could be higher than you really think. |

Take a sample of tank water
Heat to 80oC Allow to cool for 5 mins Take PO4 test What does this do? PO4 is bound into the water molecules, when not heated only the loose PO4 elements are tested, by heating it PO4 elements are released and as such giving you the TRUE PO4 reading. |

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.
 Boil to 80 degrees centrigrade not F  |
