The website appears to be 'down' at the moment, I will try to read this thread later.
Google translate :

My aquarium is a bow front with external power head filter (1000 liters per hour), I do 30% water changes weekly.

I talked with my friend in the USA its hard for him to bring bottles (and powder) so I cant get any of the Seachem products or any dry ferts.

BruceF If you are going to use a SeaChem product look inot Envy and Propel or some of the micro products in the Flourish line.

I'll try to get a Seachem Equilibrium from USA too, once again will adding only KNO3 and KH2PO4 + http://www.pfertz.com/rootferts.html have positive impact on the plants or that will mean a problem (algae)?

fis Thanks @Darkblade forgot to mention that, I have 4 T8 bulbs: Osram fluora (grolux) 18w, 6500 K 18w and 2X 8000 K 25w, the aquarium size is 830x435x480mm, no algae problems so far.

Darkblade48 As mentioned by several others, you will need a trace mix in addition to what you are planning to dose. The macronutrients and the root tabs alone will not be enough.

In addition, you did not go into detail about your lighting.

You mentioned 2 WPG, but this is an outdated method of looking at lighting. What kind of lighting do you have? How many tubes? Also, how tall is your aquarium? For example, 2 WPG of T5HO would be considered high light, and a non-CO2 approach would not work at all. It is best to not even consider WPG anymore.

If you do not have a balance of light, nutrients and CO2 (or in your case, since you are not even planning to use CO2), you will get algae...

Tom Barr non CO2 method

I added once a week KNO3/KH2PO4. While trace mixes can be added, I decided to use SeaChem Equilibrium instead. It has Fe and Mn as well as Ca/K/Mg/SO4. I will add about 1/4 teaspoon per 20 gal tank once every week or two.
This greatly enhances the growth of the plants. I also will add about 1/8" and 1/32" teaspoon of KNO3 and KH2PO4 respectively once a week or two. Note, GH Booster can be used instead of Seachem Equilibrium

Seattle_Aquarist Hi fis,

I am not familiar with Tom Barr's non-CO2 dosing method so I cannot comment on it.

Seachem Equilibrium may be difficult to find in Macedonia. If you can't locate it you could use Tom Barr's GH Booster which consists of:

50% K2SO4
25% Gypsum (CaSO4)
25% Epsom Salts (MGSO4)

Dose as necessary to maintain about a 5.0 dGH hardness.

Hope this helps!

fis Thanks @Seattle_Aquarist

So basically if I manage to get SeaChem Equilibrium all I need to dose is 1/8" and 1/32" teaspoon of KNO3 and KH2PO4 per 20 gal. once a week (Tom Barr non CO2 method) and there is no need of K2SO4 and MgSO4?

If I don't manage to get Equilibrium, will only KNO3 and KH2PO4 + root tabs have positive effect on the plants or it's better not to use them at all (may cause algae bloom?)? The tanks is running since August and I don't have any algae problems (I had only diatom algae but not anymore). I do 30% weekly water changes.

Seattle_Aquarist Hi fis,

You should be good with:

KNO3 - macro nutrient
KH2PO4 - macro nutrient

K2SO4 - used for extra K; also used to add hardness
MgSO4 (Epsom Salt) - used for extra Mg; also used to add hardness
CaSO4 - used for extra Ca, also used to add hardness

It would be helpful if you had micro nutrients as well.

Dry Fertilizers - Help Please!

Maybe this will sound funny to some of you but I have some questions

I have a 44 g. (175 l.) tank, 2 wpg and no CO2 and I would like to start dosing dry ferts, but I have a problem. I can get only 4 elements K2SO4, KNO3, KH2PO4 and MgSO4 and I can get products from http://www.easylife.nl/en/freshwater...lant-nutrition and http://www.oceannutrition.eu/en/By-W...YPE=Freshwater , http://www.sera.de/uk/pages/products...izers-373.html and next month a friend of mine will get me some http://www.pfertz.com/rootferts.html from USA. That's all I can get in Macedonia . I have some easy to grow low light plants: Anubias, Echinodorus Ozelot, Egeria Densa, Vallisneria, Java Fern, Java Moss, Crypt Wendti, Bocapa Monnieri, Hygrophila corymbos and I like to make them to look better (last anubia leafs have little holes, egeria densa leafs are small and near to the steam, Hygrophila is losing older leafs easy and new once are too yellow, some fall easy).

What do you suggest? Is it OK to start with dry ferts + root tabs? Will I need something else from Easylife, Sera or Ocean nutrition? What method to use and how much to dose? Or should I stick to low tech no fert tank?

Thanks in advance!
