Just wondering if there are other options besides the compact! Is there adifferents between 10,000k and 20,000k? And witch one is better for my tank! I've been having problems with red slime and corals not opening! I already been using RO water and have been doing weekly water changes and the slime seems to be going away. Only a little brownish tint is left. But i've heard that the lights sometimes help in the growth of the red slime and giving my invert's a problem. So if i go retro is it better than a compact and what are the up's and down of the retro? Thanks for all the reponse just want to get the take to where it should be, with all my fish and invert's happy and open. Oh and how many hours on the halid's and how many actinic?????? Thanks all!!!
The difference btwn 10k and 20k is that 10k's are a white bulb and will contribute more to growth along with color and 20k's are way bluer and will contribute a lot more to color than growth.
If your having problems with cyano, what do your water parameters look like? Also you say the corals aren't opening, so it could be bad water quality.
As for the upsides of retrofits they stand at you can run any light combo you like, you can place the bulbs wherever you see fit...etc. The only down side i can think of is that you need to have some DIY skill and building a canopy can be a PITA.
Depending on your system you would adjust the photoperiod accordingly.

You have a 29 in. tank so I would go with 400 single ended or 250 double ended.I have 14K bulbs on my tank with T5 actinics. I am going with reeflux 10k next.
What kind of corals are you going to keep in your tank?
Kind of lighting? heres a way to find out ,look at some of the members albums.If oyu like what you see ,Pm the person and ask them what type of lightingthey ae using or if you can see it in person.Also its not what everyone is using out there,Its what you like that counts .IMO
Keep up with the water changes ,and get rid of the silm.
