Dosed appropriately, they should be fine for your crayfish and snails.

There are various dosing strategies that are out there, some more common ones include Estimative Index (EI) as well as PPS-Pro.

How do those strategies work?

Read it... they both say use csm+b... which contains copper which I have been told is poisonous to invertebrates. .. snails as well as shrimp/crayfish...

EI dosing is essentially a strategy whereby you are dosing just a bit over excess nutrients, so that plants are never starved. At the end of each week, a 50% water change is conducted, thereby resetting nutrient levels and preventing them from accumulating.

PPS-Pro is the opposite, where you are dosing just barely enough to meet the demands of plants. This method requires a bit more patience, as you have to adjust the fertilizer dosage to the amount of plants (biomass) that you have.

Of course, both methods can be tailored to suit (e.g. biweekly water changes while still dosing EI, etc).

My Primer to Planted Tanks (linked in my signature below) has some basic information regarding these two dosing strategies, but I would recommend that you do a quick search of the forums for threads that cover these topics much more extensively.

I am unsure why you think EI is expensive.

For example, I am able to purchase 500 grams of potassium nitrate for around $5. This lasts me approximately a year, given that I use to dose approximately 120 gallons worth of aquariums.

CSM+B, potassium sulfate and potassium phosphate are similarly priced, meaning that I can fertilize my aquariums for about $20 a year.

Regarding CSM+B, as well as all other commercial trace mixes, they will inevitably contain copper. Shrimp food contains copper.

Invertebrates require copper as part of their diet, as it is required for proper hemocyanin production and function.

However, as with anything, the dose makes the poison. The amounts of copper that are dosed via CSM+B (or in shrimp food, for that matter) are low enough that shrimp should not be affected. Of course, there are exceptions (e.g. if you are trying to breed shrimp that have exceedingly stringent water requirements).

Well I'd like to dose as simply as possible without the measuring and mess... as far as the pricing went I was going by prices I found on ebay for pounds of the stuff I wasn't aware I could buy it in smaller amounts... someone said to dose csm+b and flourish and it would satisfy my needs...

Bump: I admit I know absolutely nada about aquarium plants... and ferts.
