It just test the ph you still need the up and down solution to adjust the ph and you need calibration fluid if using a pen. Seeing as how your low on cash and a decent pen is about $40 if it's two point 4 & 7 probably not the best for you atm. I would just get the ph kit if you don't have one http://www.zenhydro.com/gh-ph-contr...HQCR1-HZU5QOSmB9XlyiT1CBiQ2AtiH7GQaAq1d8P8HAQ
That being said once you do have some cash I would get a two point PH Meter and PPM Meter
