Hygrophila Polysperma

Just a quick review on this cracking little addition to my community tank

My water paramaters (Central Scotland)
Calcium (mgCa/l) = 11.35
Magnesium (mgMg/l) = 1.28
Hardness as mg/l (CaCO3) = 33.56
Clark degrees = 2.35
French degrees = 3.36
German degrees = 1.88
Hardness level = Soft

The plants were approximately the same height as my wee yellow/pink castle and they have more than doubled in height in just over a month! The ones in the middle of the tank have grown better than the ones planted nearer the edges of the tank... It might be a circulation problem but I'm not bothered since they are all growing at some rate, just not as quickly as others...



A side view looking across the width of my tank, the fish love swimming in among the foliage. The harlequins continuously try to lay eggs under the leaves but they are always followed by hungry neons and cherry barbs...



I'd highly recommend this plant for beginners and experienced fishkeepers alike... A very hardy plant that I have grown easily with no added CO2 or fertilisers. Just an airstone that runs when the lights are on for ten hours daily (No direct sunlight into the room either).

Lookin' good. H. polysperma is a good nitrate muncher, too.

The plants in the centre are probably growing faster because the light is brighter there, in most tanks at least the lights don't cover the whole length.
If they grow too tall, you can just cut them of, perhaps one by one, near the bottom, they will regrow and generally branch from where you cut them. It is about the easiest plant there is. It will also grow attached to wood etc, or just floating around.
