tygger August 29, 2006 August 29, 2006 My nitrates are a bit high and will be doing water changes to help reduce. Right now, my fuge is lit only at night when the halides are off. When is your fuge lit? Does anyone light the fuge 24/7?
davelin315 August 29, 2006 August 29, 2006 I do 24/7 but only because I'm too lazy to install yet another timer on the tank to handle the refugium light.
tygger August 29, 2006 Author August 29, 2006 I wonder if that has any ill effects on the critters in the fuge??
davelin315 August 30, 2006 August 30, 2006 None that I've ever noticed. Until I used it to store "spare parts", meaning starfish and shrimp being grown out to a size that they survive in the tank at, I had mysids and pods galore as well as stars, etc. I still see tiny ones, but the bigger ones get eaten by the stars and peps.
dhoch August 30, 2006 August 30, 2006 I'm on the PM only cycle (i.e. when tank lights are off)... I think there is pleanty of growth in my refuguim... Dave
sturnmeyer August 30, 2006 August 30, 2006 10pm - 6am for me. Almost the same as when the display lights are off.
Steve G August 30, 2006 August 30, 2006 24/7, but that's only because my timer is broken. People use the reverse photo period to keep the ph more stable (if they have macroalgae growing in the fuge). My Ph stays pretty stable anyway even with the broken timer.
dandy7200 August 30, 2006 August 30, 2006 One tank fuge is lit 2am - 10pm. It is a display fuge so I like it off during the hours of 10pm-2am. 20 hours. The other tank fuge is behind cabinet doors and lit 24/7. Growth is about the same.
ReeferMan August 30, 2006 August 30, 2006 Mine is on 24/7 and my PH is always 8.0 (lights off) 8.2 (lights on). To me thats perfect so i wont change it!
tygger August 30, 2006 Author August 30, 2006 Thx all. I was hoping that if I kept my fuge light on for a longer period, it would help reduce trates.
YBeNormal August 30, 2006 August 30, 2006 For those of you using the Lights of America fixtures over your fuge, it is very easy (and little or no cost) to set these lights on an alternate cycle from the main tank. Simply pull the built-in photo sensor from the LOA light fixture and extend it to the main tank area. When the lights on the main tank come on, the LOA lights will shut off and vice-versa.
ReeferMan August 30, 2006 August 30, 2006 i have one and it doesnt seem to turn off or one like that. I turn on the lights in the room and it stays lit.
YBeNormal August 30, 2006 August 30, 2006 You could have a defective photo sensor or the lights in your room are not strong enough to trigger it. Place the sensor under a bank of T5's of MHs and see what happens. New sensors can be picked up at the local Radio Shack if yours is defective.
