The power of the heat test ;)

If you do not do a heat test for PO4 you will not know what your value truly is, this is so important and leads people to think algae issues are not PO4 related as they see a zero value. As the above shows, unless you do a heat test you are not getting the true and accurate value.

Ok so carry on as planned using the Ultra power phos to the instructed amount for 7 -14 days or until you get zero reading under heat test conditions.

Ok my PO 4 are at 0PPm testing at 80 C and just before I headed to Mexico for 7 days I put in the last of the PHOs with a new batch in and now Imts sitting at 0 now so that is great just going to wait to see what Mike's recommends for the next level..

MIke Im out:sad:

Yep its powerful stuff :) If you want rid of PO4 then this stuff really kicks ass and is cheaper than most other brands too!

You now need to go onto maintenance regime of it, and then look at nutrient reduction ways to keep better ontop of the PO4, such as Ultra Bio, Ultra Bak etc.

Will sort out a tub of 500ml for you to continue the review for the next month.

thanks so you are suggesting that i use the bio and the BAK again to bring it back to ZERO Results again . if so I can do that
