Ovwr the last few months I've had a lot more algae than I used to get.
I know there are various factors I can look at but I'm trying to consider what has changed.
A significant difference is that I've moved from tap water to rain water.
Our tap water is off-the-test-chart hard. Literally. GH>180 and KH >240 with a pH around 7.2
Our rain water is GH<40 and KH<30 with a pH of 6.3
Is the change likely to contribute to algae growth?
