Mainly Rotala Macrandra seems to suffer from shrivelled growth shoots. Increasing Boron seems to help loads. Tropica have the ratio of B:Zn at 2:1 whereas most DIY trace mixes tend to have more Zn than B. Adding more B to get the 2:1 ratio seems to work. May be coincidence or not. All my other plants couldn't seem to care less. I use RO water which may be part of the problem as other people who use tap water don't always have this problem, probably because the B is in the tap water. Unfortunately I can't use tap water as half my plants just die in it as it's so hard.Amoeba said:I remember you mentioning the Zn:B ration before, but did not find any details.
Could you tell a bit more about the species and the symptoms?
Its not a substitute to TPN+, its a substitute to TPN, just the trace elements. You still need to dose the Macros on top of this.stuworrall said:ive bought some to give it a go on one of my tanks. pretty good saving if it works as well as TPN+
Yep and you can buy some dry salts and make a Macro mixture for a fraction of the price alsostuworrall said:ah, cheers paulo. must have misread the first page. Ive been doing 2/3 TPN and 1/3 TPN+ for a while on my tanks anyway so I can try it with this mix as Ive got some of the +
