browsing aquariumfertilizer.com i found that they have PMDD premix and i have heard other people dosing PMDD around here on the forum.

is PMDD like "one stop shopping", "the easy way out", "one fert. to bring them together, one fert. to rule them all" for fertilizer?

You are going to hear maney varying opinions on this. The PMDD mix is great for a casual aquarist that wants to have some healthy plants.

The idea is that dose the tank daily, and that's all. I'm using the pmdd mic from aquariumferilizer and it working great. This is the first time I've seen good growth from the plants in my aquarium. Everything is green and healthy.

that is exactly what i am looking to get into for now!
 
One piece of advice that I learned after making the switch to this.....don't forget the phosphates. ;o) While things were going really great growth wise....I started to develop green spot algae. I have since scraped it off the glass, started dosing phosphates and as of now <knocks on simulated wood> no reoccurances of the green spot.
 
Chris,

I would look at the nitrate and phosphate levels in your tank before you go PMDD. PMDD includes both of these items in the mix. I plant heavily in discus tanks and, due to diet have a relatively high phosphate level. Nitrate is average and, if not dosed goes to zero in a day. My phosphate never drops too far if I don't dose.

That being said, you may want to go with the raw ingredients then mix it yourself. This will allow you to leave out the stuff that is already naturally occurring in your tank. What's the benefit? Well, you can actually get a near perfect balance of nutrients by only adding what you need. Too much of one thing and you'll have algae!

Just my way of doing things!

Best wishes!
 
Actually, PMDD mixes do not contain phosphates, which can be a problem for high light setups since plants need phosphates and there usually aren't enough phosphates occurring naturally.

If you're going to order the PMDD mix, also order some KH2PO4 to have on hand.
