PAR readings for TMC Mini Led 400 and TMC GroBeam 600

PAR at 400mm in air is 61 uEinsteins/sec/m2,
This is almost meaningless since not many tanks are running as permanent "dry starts" ... perhaps this is some sort of misprint ...
PAR through water will be very different
 
Interesting. I am really struggling to get much growth out of my plants. Rio125 with 2 x grobeam 600 - 60cm from substrate and 20cm from water surface

2 Grobeams 600 for 125L should do the job. Aaron, do you adds ferts, do you add co2?

Michel.
 
Yep, blast tank with CO2 and EI dosing.

Without going too far off topic I have decided that I don't like the open top look and associated evaporation.

The LEDS spill a lot of light all over the lounge. So I have ordered an iQuautics 4 x T5 replacement light unit .

Will give that a blast. Had much more success before with T5
