HELP WITH LIGHTING

[carlosguy]

So i have a small 13.5 gallon nano. Its a fluval evo. I have some softies some lps and some sps.
I bought a few acros to see how they would do and some are doing ok while others browned probably due to lack of light which was expected. HOWEVER, i got a monti cap that was doing really well for about a month, then i up'd my lights and it seemed to lose color and turn a light pink (from red).
The change was this
from ONE prime HD --to--> One prime HD and 2 reg AI Primes

its been 2 weeks since iver taken down the other two lights and am currently running just one ai prime hd at blues 115% for abour 4 hrs and white up at about 25 for 3 hrs then a gradual decline until its off.

Alk is always at 9-10
calc 430-450
phos 0
trate 0

i run gfo and carbon in a reactor and a filter sock

sooo,, is this just not anywhere near enough light? is 3 primes enough? should i get a hydra 26 or what should i do

to clarify, they were fine with the single HD, then i added two more and they seemed to lose color, so after about 2 weeks of running 3, i went back to just one

3 primes on a 13 gallon? WAY TOO MUCH

I have a single regular AI Prime on a 10g and it's plenty.

So you have 3 lights on this nano? What are the dimensions of it and what light settings are you running?

but even for sps? im not sure wat the par on each is but i think its something like 100 each when running at full power.

The par on a regular AI at full blast is around 250 IF I remember correctly. You don't need insane amounts of par for SPS. Some can tolerate it, some prefer it, but not all need it. Anything in the 150-200 range is usually good.

I definitely agree that it is way too much light now.
