Malgré le peu de réponse, je continu à m’intéresser à la question et voici l'échange avec Seachem.
I want to buy the Equilibrium but I would like to know if you use K2SO4 or KCL?
Also you use something other than MgSO4 (I think it is not possible to do without SO4)
Thank you for your email. The product Equilibrium is derived from potassium sulfate K2SO4/ calcium sulfate CaSO4, magnesium sulfate MgSO4 / ferrous sulfate FeSO4 / and manganese sulfate MnSO4. You can read more about Equilibrium on its product page here.
Thank you very much for your response and the information.
I saw on a forum that you use the KCL on a product.
Which product is it ?
Thank you for your response. Likely, the product you are thinking of is Replenish our GH supplement for fish-only systems. Chloride salts are easier to dissolve in water and beneficial to the fish, but some may harm plants. For that reason, we have Equilibrium for planted tanks and Replenish for fish-only tanks.
Hello, It's me again, when you say "derived" for K2SO4 or MgSO4, ect ... is it to isolate and remove sulphate (SO4) to create K2O ?
I apologize - I may have been unclear in my previous email. We include on our product page a guaranteed analysis of Equilibrium, and a list of the chemical compounds from which that analysis is derived.
We do not put the Equilibrium through a special chemical process to isolate and remove the sulfate, nor do we create K2O. As mentioned in the guaranteed analysis (see the clipping above), Equilibrium does not contain any K2O. Certain fertilizer laws require that companies list the amount of potassium as "the amount of potassium that there would be if it were in the form of potassium oxide". However, potassium oxide makes a poor fertilizer, so most companies do not use actual potassium oxide in their products.
Thank you for the accuracy of the information.
Finally it's K2SO4, MgSO4 and CaSO4 if I understand, right ???
I'm very planted tank.
SO4 is sulfate and before I used powder, I stopped because SO4 contains sulfur 32,065 g / mol (18.4%).
I had 70 dead fish very quickly.
The parameters of my aquarium are always correct and this is not a dosing error.
Ph = 6.8
KH = 3
GH = 5
K = 20ppm
Ca/mg = 3/1
NO2 = 0
NO3 = 5
PO4 = 0.5
I thought that sulfur was responsible for this problem.
Indeed, sulfur is accumulated at each water change (amandement)
When I do a water change, I use 100% osmosis water and I add powder CaSO4 / K2SO4 and MgSO4 to be with the same parameter in my aquarium.
Just the sulfur in the MgSO4 is enough for the plants.
Everything else is not consumed and accumulates at each water change.
Friends using Equilibrium and not had a problem I stopped powders and I will anyway change the method with équilibium to try.
I wanted to be on for sulfur problem, from what I understand there is also in equilibrium.
I hope not to have bothered you with my story.
K Potassium 39.0983 2 44.8737 %
S Sulfur 32.065 1 18.4008 %
O Oxygen 15.9994 4 36.7255 %
Thank you for your reply. The components in Equilibrium are derived from components listed below in the analysis, but we are not able to divulge the exact final composition form of these components as that information is proprietary.
That being said, the forms of these final components are extremely safe as is using sulfates in an aquarium when dosed appropriately. The concentrations of all components in Equilibrium are in trace levels appropriate to remineralize aquarium water to make it suitable for keeping and maintaining healthy aquatic plants. Not to fear, the levels in Equilibrium are designed to mineralize the system without building up when dosed as directed. I hope you will find this product to provide a nice balance of nutrients for your system.
Have a nice day!
