Have a laugh at my expense!!

I recently purchased 2 lbs of PMDD from Greg Watson. Why did I purchase 2 lbs?? Well why buy one when you can buy two for twice the price. Anyways, after I purchased this stuff, I have been reading up on how to properly dose this stuff.

Lets say I add two teaspoons to 500 mL of water and dose 2 mL each day.


2 lbs = 64 tablespoons = 192 teaspoons = 96 bottles of 500 mL fertilizer.

At 2 mL a day, each bottle lasts 250 days. 250 days X 96 bottles = 24,000 days = 65.7 years!!


I will be 98 years old before I need to purchase any more fertilizer!!! Still, it was cheaper than 10 years of Flourex!!

You can always pass it down to your children and grandchildren.

And it's more practical than the two-gallon "family heirloom" size canisters of peanut butter from Sam's Wholesale Club.

That just reminded me of the 8 lb can of refried beans my buddy bought from Sams a while ago. He was the happiest person in the world when he brought it home. Showed it to everyone!!

Always preferable to read up on something AFTER making the purchase!

Here's to a long and healthy life of weed keeping.

After you switch to EI, you can use it on water change days - it will go a lot quicker when used at EI rates.

I use a tsp with each waterchange.

Still that would be 3 years worth for me.

Just double the amount of aquariums you have, and the fertilizer will last half as long

Is dosing such tiny amounts i.e. 2 ml rather difficult? I use commercial ferts right now so it's kinda hard to overdose. Also, is there a bulk chemical I can buy that is the active ingredient in Excel? I use a lot of Excel, and it is getting expensive.

Just whip up a custom solution that's dilute enough that you can easily measure the required amount. For example, my phosphate solution is calibrated so that it adds 1ppm to my 10g per teaspoon.

The active ingredient in Excel is gluteraldehyde. It's nasty stuff in concentrated form. Search for it on Google and this forum and you'll find plenty of info. I expect it would be hard to purchase without some paperwork and a company name to do it under.

You are definately a "glass is half full" type!



Well, I got the PMDD in the mail, and am preparing to dose. Of course, the LFS by me only has ammonia, nitrite, and nitrate test kits. If I have to get some test kits online, let's hope I don't order 20 years worth.

Anyone want to give me an estimated dosing amount of this stuff for a 29 gallon tank?

Hey olsaltybastard,

I've got a 30 g tank and I'm dosing PMDD (Sears-Conlin recipe). I'm using 0.75 mL per day, and this keeps my nitrates about 15 ppm. I find that I need to dose Flourish phosphate (haven't purchased dry K2HPO4 yet) 1-2x per week, adding 0.5 ppm per addition. I also occasionally supplement with potassium (K2SO4) if necessary (i.e., if I see pinhole spots on my leaves). I still have 2 large angel fish, 12 white cloud minnows and 2 cories, so my bioload is fairly high, which likely explains why I don't need to dose the large amts of macros that you typically see with the Estimative Index system.

Good luck!

Thanks Stan,

I just purchased pH, nitrate, and alkalinity test kits. I have to return the alk as it didn't come with the instructions or any color comparison sheet. Either way, now I can at least begin to test the water and see what's going on inside.
