new MH bulbs, acclimatize tank?
Got couple of new 250W 14K Hamiliton MHs. First is replacement for one that burnt out after 6 months, second to replace other bulb that's been in service for a year. Both same wattage and spectrum.
Read that should acclimatize, either by reduced photo-period or screening, as could shock inhabitants because of intensity of new bulbs.
Real world check, wondering if anyone actually does this?
