For the benefit of anyone that doesn't have a degree in science here is EDTA http://t1.gstatic.com/images?q=tbn:ANd9GcQL2EpAVyqTCo06XhAIo636Tce8R-wows44j40Y30vxWOzCfbU&t=1&usg=__rQbDkuPIio2sRDHhez4Jt3hO_p0= The M is a metal and can be Iron or magnesium or something. Darrell, whilst I have the...

ATPase is what kick started my fascination with biochemistry/structural biology. Had to do a presentation on it and was blown away.

Yes I meant tonic salt. Anyone happen to know what salts are in tonic salts?

Oh and to add, you might be surprised how much salt it takes to make water brackish or marine!

One small teaspoon will not do the damage you suggest Garuf. If you use RO all the time it can be useful to add a small amount of tonic salt. I have also read this is beneficial Grandb3rry and used to do this with no ill effect to plants or fish.

Quick roses question, if the leaves have lots of black spots and the leaves are dark green or yellow is this a deficiency or a disease?

Heya Chrisi, Yes try fridging, or try freezing some. Try using water that you pre-boiled (and left to cool). Try using a sterilised bottle. Or try all of the above!

Cheers for clearing that up Cegipedia :D

I may be wrong, but then again I'm in the lab all the time and if I pick up a bottle of say epsom salts (MgSO4) I wouldn't expect it to be a mix of dry powders magnesium oxide and dry powder of sulphate.

Well John thats the thing. Chemical formulae are just that. Its not just this and that "mixed together" they should be chemically covalently bonded together. From what the ingredients say I would have thought the phosphorus is covalently bonded with oxygen and the potassium the same. If KH2PO4...

See I was thinking about the difference between AE and garden ones. Look at the label, it says Potassium phosphate. Look at the ingredients and its Potassium oxide and phosphorus oxide. This is not the same as potassium phosphate and I do wonder if plants are able to utilise it as such. I don't...

I was looking for chemical structures to show why the percentage of N changes and found this:- http://bcn.boulder.co.us/basin/data/BACT/info/NO3+NO2.html It is a good page with useful information on urea and ammonia. I might add that just because urea has more N %age wise it does not mean it...

Wow it is some nasty s**t http://en.wikipedia.org/wiki/Glutaraldehyde Quote "A polymerized isomer of glutaraldehyde trademarked as polycycloglutaracetal by Seachem Laboratories, Inc. is the active ingredient in a product called Flourish Excel, a fertilizer for aquatic plants. It is claimed that...

Where do you buy TPN+ from? Unless you get that free too :P

I'll go with other, as my tank has a high stocking of fish so I don't dose anything atm... I would dose Tropica plant nutrition+ but cannot find it anywhere... Grrrr...

Well done Ceg for an accurate and very helpful summation, the thread was going off the rails a tad and perhaps would be better locked now? PS I did not know anything about PMDD, so cheers for that!
