Hi all.
I have just set up a tank - Saturday just gone. Tank size - 180 lit. This tank is now cycling. I'll introduce some corys, ottos and perhaps some shrimp shortly to start the biomass.
My 120 lit tank has a PH of 7.2. Our water is really hard and so the current PH in the 180 is 7.8. However, the GH in the 120 is OK. In the 180 it is too high.
What would be the best way to reduce the GH. My budget is unfortunately really tight so cannot afford a RO unit. CO2 will reduce the PH but I doubt it will have any effect on the GH.
I'm now looking for an affordable (cheaper) means to get the parameters right. Will this hardness reduce with time as the tank cycles ?
Looking forward to hearing from anyone who has any suggestions.
