sps nano help

[Mantis Pimp]

Ok im thinking of starting a SPS nano but am concernd that if i use my 150W MH it will have alot of evaperation and cause huge salinty fluctuations because its only a 12G. Is it possible to use a 75W instead? Im instaling a sump so it might end up being 20G total but still im sure it would cause great amounts of evap.

just keep the light close to a foot above the tank. plus you will need 2 drip kalk.water (or a calcium reactor) so just set it to drip at the right rate to keep up with the evap.
