Struggling With Plants And Algae

Yeah read that but water is not so crystal clear.  Also the other option is RO water so not sure what's happening with mine.

Started to look at CO2 now haha

Thanks @Matt

Would I be right in saying lowering KH would impact PH? Have I got that right?

Or is it that you can’t lower PH until you’ve lowered KH? Meaning the lowering of KH doesn’t directly impact the PH it just means when lowered you can then use say aqua soil and will see a drop?

You can still have high pH with low KH. My KH is 4 dH and my pH is ~ 7.4 (it varies slightly according to the time of day).

KH buffers the pH. It is almost impossible to change the pH with high KH. But it is easy to change the pH with low KH. I don't mean by adding chemicals, this is always a bad idea, but things like driftwood, leaves etc produce tannins which are acidic and can lower pH - if KH is low.

Your KH is quite low. You could try driftwood etc, but I have to say that my wood has no impact on my pH. But wood that colours the water brown would have more impact - but you'd have to put up with the tank water being brown

CO2 has not interested me as I have slow growing plants in my tanks (except for floating plants which can get it from the air) so I don't know much about that aspect of plant keeping.

Tank, fish and plants all looking great - well done!   

Looking good! I take it the anubias rhizomes are above the substrate?
