Hey,

Just a quick question if I may. When dosing a tank using the EI method, what are the implications of doing water changes larger than 50% each week? Do you just have to dose differently by adding more ferts for example? Or is there more to it?

(Ok so thats actually three questions ;) )

Its ok to do pretty much any size water change over the 50%, in fact the bigger the better in way ways as it removes algae spores and other things that might build up in the water. The 50% is only to stop the fert levels getting to high, i.e. if you dose a total of 3ml of PO4 a week then the most its going to 6ml in the tank. Doing a larger water would just reduce the max it would get to.

So (for example) would you need to dose more PO4 to allow for the larger water change? Or have I got his totally backwards?...lol
