Hi Jim
Yes this was confusing for me at first as well. Here are a few recommendations.
I dont want to sound like a pusher here but you should pay a visit to the following thread within APC
http://www.aquaticplantcentral.com/f...v2005-new.html
Once you pay a visit you should read the articles in the order presented. Within the articles you will be provided with recipes for mixing solutions and explanations of how the PPS sytem may be used.
You should also download the XLS file as this will help you keep track of your dosing regimen and both Edward and I are usually here to help out with questions if related to PPS (Perpetual Preservation System)
In addition you may also choose to post your XLS data in the following thread
http://www.aquaticplantcentral.com/f...eets-here.html
this is where you get personalized service at APC and a look to see what your dosing and anyadjustments required if any.
And to add to all this there is yet another discussion thread
http://www.aquaticplantcentral.com/f...on-thread.html
Here you will find a wide cvariety of comments that will aid in your decision and knowledge.
Boy I do sound like a pusher, a thread pusher.
In any case my moto is read read read ask ask ask and then ask some more questions.
Good luck and keep us posted
