thanks. a little luck goes a long way in this hobby. yeah the thermal shock is nice going from outside to in, but visa vera aahhh. i always think of that "good dog" commerial. will try to adjust it when the main lighting goes on and have been thinking of getting a clip on little plastic fan for the sump. use to have one but my better half took it to work and i have not seen it since. it is suppose to get up into the 100's this week. geuss i will go surfing all day get nice and toasty then walk into my new freezer house. i do think the price of the T5's will go down, many warehouses are changing their halo and MH lighting to the T5's, cheaper running cost. plus they just really started to show up in all the LFS. but like everything for most change is hard. even though we know there are different ways of doing things that work equally as well, most will stick with what has worked in the past. i have two systems one with a skimmer one not, both doing great. the no skimmed system houses softies and zoo and stuff, they eat up a lot of zooplankton, photoplankton ect..they seem to do better in the unskimmed system(much bigger extenstions seen in polyups). sps and lps in the skimmed tank, sps dont do so good with an unskimmed system LPS had mixed results. but most would say no way to a unskimmed system for whatever is in the tank and never even try it to see if its better or not. i believe in providing the best enviorment for the animals as i can. money being the limiting factor. for shallow tanks T5's are a good option. look at it this way just the fact that so many are having success and that so many are comparing them to MH and the fact that many "experts" are changing what they say, says lot about them. most that say no way have never even seen them, maybe in a photo or box but not on a tank, let alone the effects they have on the corals. i always like to check things out for myself, of course do research but i dont mind being the ginnie pig from time to time. what got me to try them was seeing them on a awsome tank at the LFS, with mostly sps, for the past couple years. that and all the arguing i see and do lead me to testing myself. now i must check them out long term. good luck to each of you and happy reefing so until next time be seeing ya lates.
