i get the feeling you don't like me very much sarah... what i meant is that I don't have the room for a chiller. simple as that. right now, my water temp is topping out at 80, 81 on occasion. I'd like it to stay at that temp, but get more light si i figured retro t5's and a se 250 watt mh. I dunno what kind of wattage to replace the 65 watt pcs though so i am asking for a reccomendation. I found a 25watt mh, with 10k xm bulb, magnetic ballast, and reflector... all plug and play for i believe 140 shipped. seem like a good deal to anyone here? I was even thinking that i could use the 10k 250 watt, and use a 20k on the 175... my only worry is heat, and if that would just turn my tank into a boiling fishbowl... which would then necessiate getting a chiller, but i don't have space for one, but i have fans in my canopy up the wazoo. ***? my green anthias just ate a blue reef chromis... anyways, guess whatever i end up doing will put me even further back from getting a digital camera i could post pics with... oh and i apologize for my lack of effort tracking whose tank had what lights and what rock in it and what was on the way and etc... I hope everyones tanks turn into the reefs they want them to be, because 2 jewel damsels that i have are starting to pick at corals... and i now have to tear everything apart to get them out. and i was just starting to like how the rocks are set up :mad2:
