Too Much LIGHT ??

hi guys new reefer. my tank is really starting to come up well al the algae and stuff has died off now ad my fish are fat and getting huge cant say the same for my corals they seem a ltitle limp i dont really have much sort of just a tester to start off with before i start spending more money on it n e wayy ..... i have a metal halide 2 250w globes with 4 t5's 2 blue and 2 white running sdown either side and 2 moonlights i think they are. i have my t5's coming on from 8am to 8pm.. my halide comes on at about 11 am to around 4 pm i thought this would simulate the middle of the day. any way is there a way to dim the lights orsomething and is this light schedule ok also i never turn the moonlights off

 

Hi Chris B - how big is your tank - its seems large if its the one on your Avator?

doesnt seem like to much light to me based on what I see others running on tank specs and in the "show of your fish tank" section on this forum

I dont own Halides so Im not sure about dimming issue -

 

umm the tank is 4 foot by 2 foot high i want to be able to dim the t5's

 

Hi Chris - Im pretty confident when I say T5s

 

im pretty sure that didnt make sense

 

Yep, hadnt finished and accidental click of mouse

I dont think T5s are dimmerable - as you need a specific ballast that will operate under conditions of reduced input

 

ohhhhhhh ok thanks man its hard to get a response on here sometimes though iwould like more comments on the lighting shedule that im usingp please anyone

 

no worries - what you keeping in there? as that will make a difference to the replies you get

list the species and it will help

 

well the only one that i really know what its called is a jardini its withdrawn and died around the edges i think cause it use to be heres a picture of what it looked in my old tank its the big white one

 

here is a pic from about 2 days agoa nd as you can see none of them are doing so well and a few are missing because guess what there dead much to my dissapointment
