Re: Nutrients + Equilibrium?

One of the tanks I tried the procedure in got a coating of diatoms on
everything. The others either showed no noticable change or improved.

Baking soda works fine, but my advice was for *if* you wanted to stick
with Seachem products. Baking soda adds a lot of sodium. Sodium can be
a problem in extreme cases. Alkaline Buffer contains bicarbonates of
potassium and magnesium as well as sodium, so it should offer a better
balance. It also costs more. Is it worth the extra cost? I don't
know, that's up to you.
Yet another possibility might be to get some potassium bicarbonate from

Well, different complaints prompt different advice. I suppose I could
get around this problem by giving the same advise for every problem :)
Your plants all turned blue? Change the water! Your fish are all doing
the rumba and you weren't invited? Change the water! Your E.
macrophyllus has grown emersed and now it's demanding a blood
sacrifice? Change the water!
> What is wrong re the extra magnesium?
There's nothing wrong with a little extra magnesium. However, if
magnesium is there at concentrations that are a lot higher than calcium
(and honestly I don't know just how much higher that is -- the
references don't say) then it can interfere with plant uptake of
calcium. I think it can even mess with the plants' ability to take up
potassium. All in all it's a good idea to balance the calcium and
magnesium. Calcium is usually found in fresh water at concentrations
considerably higher than the concentration of magnesium.

I'm not aware of any problem with chloride at reasonable concentrations.

Suite yourself. Did Tom really advise "resetting" the tank once or
twice a week?
