hi,
with persistant algae blooms i'm regreting not buying a ro/di filter. currently i cannot afford my own and have resorted to ro/di from the despensors at local grocers. i tested it intitaly but used a SW tst kit before mixing the sample with salt, so my negitive reading was wrong. now i've realized the water i've been using shows an avg. 0.5-1.0 of p04.
concidering my finacial status, are there any local sorces that are reliable and cheap? i was spending 1.75 for 5gal at the water despensers. as far as i know the surounding fish stores sell water for $1 a gal, but provide consitant quality. are there any local vendors that posess bot saving w/ the same quality?
thanks for your time and concideration,
david
