Good to know! Thank you!

Thanks for the article.

I'm wondering if potassium sulfate be substituted for posassium chloride? I already have some potassium sulfate handy.

After reading the following information:
Quote:
Muriate of Potash: It's odd how this old-fashioned name remains in use! Muriate comes from Muria, the Latin for brine. Muriate of potash is potassium chloride containing between 50 and 60 per cent potash. It was deposited eons ago by ancient seas and should be considered a natural product, blessed by organocultists, but it is not. Its chlorine content passes off rapidly when applied to soil. As explained under soil organisms, however, muriate of potash is harmful to certain beneficial bacteria. Some authorities think sulfate of potash makes a better potash fertilizer.

I'm a little concerned about the potash. Is there any truth to this?

Hi,

I would like to say thank you for such a detailed post. I'm new to planted tanks and this is by far the most helpful site I've seen.

I'm about to give the top soil a try, but i was unable to find the 2 items listed below.


Dolomite (I bought Dolomite for orchids at Bunnings-then found out I shouldn't be using it..)
Muriate of potash (found some at bunnings as well but it is in a packet of soil)

Does anyone know where in melbourne-aus, I can get these from?

Also the Top soil I bought has something called a "Wet agent" can i still use that?

Hi _PhanToM_,

I'm in Brisbane-aus and couldn't find any suitable soil in bags at the Bunnings here. It all contains wetting agent, mulch and fertilizer. In the end I went to a local landscaping supplier and bought plain top soil. It's grey with a sandy texture and looks like the stuff in the article.

Dolomite should be available at K-mart etc. Why don't you think you should be using the one you bought for orchids?

I'm going to substitute Sulfate of Postash(K2SO4) for the Muriate of Potash(KCl) unless someone can come up with a downside. I've used it previously in my tanks as an ingredient in liquid fertilizer and nothing has died so far . I can't see why it would cause any harm and the chloride in the KCl won't be providing any benefit while the sulfur can be used by the plants. The Muriate of Potash doesnt seem to be readily available here in any case.

I won't be going nuts with either the dolomite or potash. Just a little sprinkle.

Hi Technics

The reason I dont think I should be using Dolomite from a garden store is because I read a reply on this thread.. it said.

Thanks for your response I will be going to K-mart tomorrow and will go look for top soil that doesn't contains "wet agent".

I searched all over Adelaide for top soil in bags and no one had any. Bunnings sell top-soil but you'll need to speak to someone there about it. They usually have a little sample shelf near the outdoor section.

Muriate of Potash is a old fashion name it is also known as; Potassium Chloride; Potassium Muriate; Potassium Monochloride.

soil with wetting agents in it is probably not going to work. Most agents work by eating through the waxy build up on the soil to allow the water to pass through easier. But they also can eat the waxy protective layer on roots, leaves and new stems, damaging plants. Wetting agents are used more in desert areas where water is more short supply.

maybe you could just grab a shovel, that's what i had to do in the end as i could never find just regular top soil.
