James, is there any reason why you add extra K as potassium sulphate as the DIY tpn+ has over 3x as much as the tpn+? Is it possible to leave this out but maintain the same benefit? Are the ascorbic acid and potassium sorbate just there as stabilisers to prolong the "shelf life" of the product...
Understand about the lighting and the generalities of the rule. As long as a high light plant will grow healthily, albeit slower, I don't really mind. There does seem to be a lot of guess work in this- bit of trial and error will be fun.
Flicking through the Tropica catalogue and picking out a...
Ideally I would like to keep light levels down so that growth rates are down, but as I understand it certain plants won't tolerate this even if they are given adequate co2 and nutrition. Essentially I would be happy with a low light low tech tank but with a wider range of plants available to...
Thanks for that, certainly clarifies a few misconceptions I had. Will have to pick up a good plant biology book up some time.
What I am hoping to do is be able to grow a range of healthy plants, but not require the intensive dosing regimes of EI. I plan to start co2 first and then later up my...
Will a plant itself with low NPK but with sufficient co2, light, and micronutrients grow healthily? If a plant acclimatises to a low npk environment, then surely you would not get the decomposition, as the growth would slow to accomodate the amount available. As I understand it higher plants use...
main reluctance for adding macronutrients is the potential risk to the fish, as I thought that higher nitrate is detrimental to fish. However have read tom barrs article rebutting this so less worried and more ready to top up, however ideally without 50% weekly water changes- have to do more...
What would be the effect of using only additional micronutrient fertiliser in a 2 wpg tank with co2 (30ppm), N/P/K being provided by fish waste?
Would all the plants grow until the NPK is a limiting factor or would this imbalance suit algae disproportionately leading to problem algae?
