arthurjob Reviewed by arthurjob on . water problem hi, ive just recieved my gro tank 205 thru the post. the problem i got is the instructions say to soak the rockwool cubes over night in ph 5.5 - 5.8ph water. the supplied ph graph only shows up2 6!!! how am i meant to go lower. also, the measuring beaker supplied doesnt have any mls on the side and it doesnt say how much the beaker holds lol. i tried a little tap water to 2 drops of ragent or watever its called and it came out the worst (highest on the chart) which is 7.6. wud i be better using Rating: 5
