Ok so I'm about 4 weeks into my first aquascape and the tank is nearly cycled...showing 0.25 ammonia and 0.25 nitrite with 10ppm nitrate. I'm running an ei dosing schedule with a 50% water change on Sundays. It's a 64 litre tank with a pressurised co2 system pumping around 2bps and no fish in. But, when I got my water tested today my PH came back as 6. Unfortunately I don't know the kh and gh so I was wondering whether this low ph is detrimental to the tank? I'm trying to grow a dwarf hairgrass carpet which is showing encouraging signs of growth and there are 2 pogostemon helferi and 2 ludwigia glandulosa (going in on Thursday). My drop checker is a nice lime green so I figure there's enough co2 in (running fluval 106 external canister and a hydor koralia 900 powerhead) and enough flow but I'm just a bit worried about the ph level as some threads on here say to forget about the ph and others have said the cycle crashes below 6. So if anyone can help if hugely appreciate it. It may also be worth noting that I intend to put around 5 amano shrimp in and I read that soft water isn't good for their exoskeleton. So please, help me out?
