Reducing Ph In Planted Tank

[CLOSSIE]

OK.
I have a 30USG (ish) tall, with pea gravel, plenty of planting, wood and DIY CO2.
PH is hovering around the 7.4 / 7.5 mark.
I have already got a pair of Apisto's in the tank and have been trying to get the PH down to around 7 which is more like their wild environment.
So!. The question is how best to do this.

Increase Co2?
Filter water through Peat?
Add Chems (not the way I prefer to go).

Does anyone have any guidance to share.
The Peat sounds the best option, and I was wondering about the Eheim Torf Pellets (are they any good?), or should I just put a stocking full of peat in my change bucket and leave overnight being topping off the tank, or should I put some in my filter.

Not sure if this fits best in planted or New World Cichlid section, but thought I would give you guys first stab..

Thanks

Hi,

To be honest, I never worry to much about pH. Is the fish happy, feeding?
If so, you've cracked it

If you have plenty of plants they will benefit from CO2 and that, in turn, will lower CO2
