Its 60 bucks for 1 L, Seachem excel would cost much less, unless the 1 L extremely concentrated.
..or you can just use carbonated water, plenty of co2.

I didn't know if DIY excel had been discussed yet. My dad's a chemist so I'll see what he thinks.

I have to mail order it which makes it more expensive for me.

If your dad's a chemist then can you just get a non-diluted solution from him?

Issues with isomers

One thing to note about the discription is that it is an isomer of said chemical. You'd need to check that this isomer would still behave the same way and be processed by the plants in the same manner since there are no guarantees.

Excel is 24% AI.

You'd need to buy a large amount to make it worthwhile.

www.Gregwatson.com is considering selling it.

Excel is 37.99 for 4 liters at Big Al's.

Why am I hesitant to put anything with "...aldehyde" into my fish tank?

LOL. But then again we put chlorine in it, sodium, and plenty of other elements that in thier pure state would be quiet a bad idea.

True.

That 1 ltr of 50% Guta would be equivilant to 20 ltrs of Excel. you would have to mix it 20parts water to 1 part guta. to get to the equivilant dosage of 2.5% Guta in excel. So that is actually a great deal IMO.
