Hey

Just wondering if anyone ferts their tanks with a PMDD mix? If so what recipe are you using, and how do you gauge if dosage rates of the various components are right?

I've seen various suggestions for determining appropriate dosage including monitoring iron or nitrate levels, observing the plants for growth rates & deficiencies or routinely dosing to excess then compensating with large water changes.

I'm considering starting a more consistent ferting regime, primarily for my 180g, but if I get decent results I'll probably end up using it on all of my planted tanks. Until now the 180g has been reliant on Dino Dung and fish waste. The tank is still very low light so I don't think I will need to add a carbon source and while I have got quite a few plants growing in the tank atm, I think they would do better with a bit of a boost from a regular ferting regime... PMDD seems to be the most cost effective option atm for achieving this with a big tank.

Any thoughts / suggestions / input?

PMDD whats that ?

PMDD = Poor Man's Dosing Drops

Basically just a recipe for fertilising aquatic plants... sounds like it could work out pretty cheap compared to comercially prepared alternatives

A basic intro article can be found HERE]http://www.aquabotanic.com/PMDDprimer.htm[/link], and more info [link=HERE. Happy reading

thanks gone but does the epsom salts harm any fish ?

Hi,
The Epsom Salts that are added are the source for the
element Magnesium Mg. In the dilution mentioned in
all the articles for PMDD it is not enough to cause
problems with the fish. Additionally with regular water
changes it won't reach a dangerous concentration.
