Hi all, firstly, George if you are reading this I researched this light and others similar to it and made my decision. The review video you posted had a small sway on this decision so I do not hold responsible at all for my issue in any way, but I’m hoping you or someone may have the key. I purchased the chihiros vivid 2 in October 2020. The light is very good and I’m happy with my purchase...but.... I cannot get plants to even remotely turn red, I have tried everything from upping co2 to drastic levels, limiting nitrates, adding iron, moving light closer and farther away form surface, and intensity. Also done these in various combinations in 2 week intervals. Nothing works at all. I’m now scratching my head and cannot see why this is happening. It’s my 1st time using leds and iv always been on the side of fluorescent for planted tanks but thought let’s give them a go. In the past iv had absolutely no problem with getting plants to redden up. I have a good few various species in the tank I have h.Cuba that is doing really well so I don’t think it’s any issue relating to co2, distribution, ferts, etc. Plants all pearl within a hour of lights on and growth rate is excellent. Species I have been using as markers are, rotala rotundifolia and Ludwigia palustris. Neither will change. Both green
Light is chihiros vivid 2 130w led rbg
Tank 800x400x400mm approx 100litres
Ph 7.2 pre injection, 6.5 at end of photo period
Kh3-4 gh7
Ferts delivered with ei dosing @ 10ml per day of each macros 1 day micros the next
Slightly modified mix more phosphate to control green spot algae that is almost none existent now
Co2 wise drop checker is yellow by end of photoperiod, no issues with fish, on hour before lights and off an hour before light off
Dose excel everyday apart from Sunday @ recommended dose
Iron dosed for a month, aqua vitro at stated dose level
Water change religiously every Sunday @ 50% sometimes 60% and nothing dosed that day
Photoperiod is 6 hours, half hour ramp on 40% red, 30% green, 40% blue
Fish and shrimp stock, 2 endler guppies, 5 ottos, 5 amino shrimp, 5 red cherries, 1 albino rainbow shark
So my questions are
1. Are led’s generally powerful enough to do what I want to do?
2. Am I doing something wrong that is stopping these plants turning red?
3. Is it time to sell the led (which I don’t want to) and go back down the fluorescent road?
Any help and advise would be greatly appreciated and many thanks for reading
Thanks Andy
