1. The sock/bag that I see on some tank drain lines to the sump... is that necessary? And if I don't want to have my drain line diapered is there something else that I should do in the sump?
2. Why do I always see the auto top off filling into the return section of the sump? Wouldn't it be better to top off in the drain line section or the refugium area so that the fresh water gets all the "good stuff" before going into the DT?
3. Ok, I've jumped a little past the sump and started looking at lighting too. I don't want anything that puts off alot of heat (small house/menopause) so I've ordered a
compact PAR38 6500k to see how well it works. I'm hoping that I can mount four of these over the tank. If it does work, I'll have less than $100 in it. Has anyone seen these used?
