Hey Some One Can Recommend For Me What The Best Par For High Tech Tank ?

50 is a minimum if with good CO2. You can grow almost all species with this and would have some room for error.

90-110 is best;
Better growth, more coloration, higher plant density.

Although they both do, the latter would require a rich fertilisation regime with high/stable CO2, perfect maintenance, large frequent water changes and regular trimming to avoid algae. Basically, overall good and healthy growth to avoid algae.

Edit: I also vote for 100 PAR like @Phishless !

Please feel free to ask any further questions.
