I resently went skimmerless due to bubbles and space requirments for a fuge. All is going well with 0 on the trates an phos.

Now I want to tackle adding 1-2 gallons a day of water.

So the question is with a mixed reef and a 24" high tank can pure t-5's do the trick over my (2) 250 watt MH and 2 39 watt t-5?

Heat is not an issue temp wise but I'm assuming is a large contributer to evaporation.

Please comment freely.
