| | Re: PAR meter rental from Bulk Reef Supply
Is this for a reef tank or planted?
A cheap lux meter should be good enough for planted tanks.
In a reef tank. Buy a birds nest colony. Chop it up and glue the frags all around the rocks. If they turn brown, you need more light. If they turn white, you have too much light (raise the lights if there's a hot spot directly underneath the light). Between those two colors is the goldilocks zone. The money will be well spent because now you'll have some nice growing corals instead of a rental fee.
