Price being the same one should always choose Amazonia over Eco Complete. Amazonia is NPK enriched while Eco is not. This is especially significant for those who don't like fertilizing the water column. Amazonia is also a nicer substrate to work with as it's easier on the hands.
thing is its not the same price though, i can get a bag of eco complete for about Â£18 inc delivery,
the ADA stuff is about Â£35 inc delivery. Thats a monumental difference and on a 240L tank i cant justify that, its alright for you guys with tiny 60cm things but when you have double that (and being im only 17) i cant afford it.
if there was a better alternative that covers both grounds id be happy to investigate but sadly i dont think there is.
Hmm, that's odd. I distinctly recall some time ago that these were comparable in price. In any case if you plan to do the self-enrichment then there is no point in buying EC. Why not just use Akadama as JamesC has demonstrated? If color is an issue then you can use any similarly colored inert gravel. EC does have a high CEC though, but every thing else about it is marketing hype. As another poster pointed out, it's heavy (not the least of which is due to the fact that there is water in the bag) so shipping charges will be an issue. I don't see the point really, especially if you plan on dosing the water column.
One has to be careful to avoid "mind-set" on a product. Just because someone else reports success using a product, it does not mean that the success was a direct result of using that product, unless that product was specifically tested by isolating it's effects from the effects of other factors in the tank. Growth performance is a result of many factors, principally CO2 and often in concert with water column dosing. So if someone states that they had success using EC, it could easily be that their success was in spite of using EC as opposed to because of it. Something to consider.
