Good Morning All, I have just recently re-entered the hobby after a 14 year hiatus. Obviously there have been a number of improvements in the last 14 years. The piece of equipment I am interested in a a dosing/top off pump. Can anyone tell me exactly where the water source that would be in the pump comes from? I have a refugium filter as my main filter. I also purchased a RO/DI and my tank is currently cycling. I am still in the process of obtaining equipment for my new tank so any and all advise is appreciated. Thanks, John1948
I have just recently started a new reef tank after a 14 yr. hiatus. I'm a little confused about lighting options. Can anyone tell me the difference between T5 and VHO lighting? Is there a difference? Or are they the same type of lighting? Since my return to the hobby, I have discovered that there have been some wonderful new technological improvements and lighting is an area I must reeducate myself. Thanks, John1948;;
