the dosing im doing is going ok, i can always adapt it if required.
Bluedave: Ceretrea: Is there a way of calculating how much light you need? Trea. Depends on what plants you want to keep and whether you want to muck about with CO2. With lighitng levels of 2 WPG you should be able to grow most things except the really light loving plants. At 2 WPG you might want to consider CO2 but not essential. You start going above 2WPG and you are likely to need CO2. If you haven't got 2 WPG just choose plants that need low/medium light levels.

Sorry, what I mean't to ask was : How do you calculate what wpg you have?

look at the light tubes you have - should tell you there wattage (9,18,24,36,55W are all common), then work out how much water you've got in the tank (width x depth x height in metres) this gives you the total water in litres. Divide by 4.55 to get gallons then simply divide total watts of tubes by gallons.

Was meaning to ask about your Rena 120 - you've listed it as 250 litres - i thought they held more than that?
Mines a 120x40 and 250l is when its empty. the 120x50 holds more
