Epsom Salt... Query...

Wat is the dosage like?

Magnesium Sulphate (MgSO4 +7H2O) is commercially known as Epsom Salt. Magnesium is required for the optimum growth for plants and yield whereby getting more fruitful returns. Don't know if it's good for fish in the long run?

Epsom salt, or magnesium suplhate heptahydrate (MgSO4.7H20) is a laxative and also used as to faciliate electroyte balance within the water.

Magnesium is good in trace amounts in the water for our fishes. It can be used prophylactically in our water to help facilitate osmoregulation, as part of the ion exchange mechansim.

Magnesium is also required in trace by both fish and aquatic plants, and therefore a trace element. Thus, for people like us keeping planted tank, we do dose magnesium sulphate in there.

It is also responsible for general hardness in our water, thus I'd usually adjust my magnesium dosing according to the gH I'm trying to achieve in the water. Right now I'm using Seachem Equilibrium, which contain mainly calcium and magnesium salts, and dosing enough to raise the general hardness from 3dH (tapwater) to about 5dH weekly.

In my opinion, it is alright to maintain about 5ppm of magnesium in the water. Unfortunately, I've yet to come across a test kit for Mg.

Ohh.. so empsom salt is a laxative...

then better dun use....

Thanx bros!!! Luckily i listen.... Thanx..!!!

Thanx hobbit for your clarification though its very very deep.....

Not too clear about what u were trying to say there...

Hi fish fish,

No, I don't mean you shouldn;t use!

In high amount it has a laxative effect, but at low concentration like at 5-10ppm, it should be beneficial for the fishes!

In fact, some may even recommend using epsom salt for cases of fluid retention, for symptomatic relief.

Haha, I use MGSO4 weekly instead of NaCl.

Hobbit,

So for healthy fishes, would u recommend using 1 table spoon of this salt for a 5ft tank after every water change instead of dosing with aquarium salt???

Pls advise...

Hi fish fish,

I've never used that much before. I'd use about 1 flat teaspoon in my 4 fter weekly, till I switched to the current Seachem Equilibrium.

With it, I usually add till I acheive about 5dH in gH. My tapwater is 3dH in gH. However,the Equilibrium also contain calcium salts which would also influence the gH.

Cheers,

Kenny

is this only for planted tanks or does it include bare tanks?

[Hobbit6003]

Hi agitato,

Yup, I'm using in my planted tank. I think for fish only tank, it should also not a problem.

Using the Seachem Equilibruim, it does recommend up to 1 tablespoon of it per 80L of water, which would have risen the gH by 3 dH. But do bear in mind that Equilibrium also conatin other salts and not just MgSO4.

Cheers,

Kenny
