well this ones been setup for a year or so - the only difference is the location - i use to be in the lounge and only got morning sun for about an hour then nothing but artificial light for the rest of the day. now its in the kitchen with a good amount of light. im trying the blackout idea for a few days and will see how that goes - does it need to be totally black under the covers or just enough to stop the sunlight etc from getting to the water?
i tried a few 40% water changes over several days but the green ness just came back overnight !! so that didnt work.
what test kit will cover nitrogen, phosphorus, potassium, calcium, magnesium, and iron ?
i have filter wool in my fluval 204 but maybe i need to be cleaning that out more often ?
