We got our ph tester from a local hydro store. You can also buy them online, from pet stores, and most likely anywhere pool supplies are sold. Generally, tap water has a pH greater than 7.0. I use a quick and relatively inexpensive product to lower pH when feeding, called pH-Down from Advanced Nutrients. A 1L concentrated bottle runs around $16 bucks, and you would only need to use a couple drops per liter of water to regulate your water pH.Thanks. Hey where would i get a ph tester lowes or like a pet store and if my ph is off how can i fix it.
You can also use anything white...like posterboard...White reflects somthing like 85-98% of light where aluminum foil is around 60% and a typical mirror is lower than that of a white surface(mirrors reflect around 87%-93% due to the light going thru glass, reflecting, and then going back thru the glass). Save youself some money and either just paint the walls with a gloss white or get some posterboard. Mylar would be your best bet with its reflectivity at around99%, and it is also very cheap.well picked up a mirror today i can use a mirror instead of like foil cant i for reflecting light
