The only cost for "upkeep" is water, electricity and ferts. If you have a 90 now, wouldnt a 180 just be twice as much?
That's what I was thinking. Don't forget time involved in maintaining the tank (trimming plants, etc).The only cost for "upkeep" is water, electricity and ferts. If you have a 90 now, wouldnt a 180 just be twice as much?
+1 My 75g bookend tanks are high light everyting else is around 2wpg (I know wpg is a junk measurement). Medimum light is way easier to keep up with and 95% of the plants do fine just growing slower allowing up to 2 weeks between trimmings.I went more low tech with my 210 just for that reason. Still use CO2, just keeping the wattage low.
