I like the aqueon pro. Or even the regular aqueons there alot at the store but amazon has them cheap.
also I have another 29 gallon tank... I tested all of my ph numbers... the 29 gallon is at 7.4-7.6.. the 55 witch has texas holey rock (limestone) is about 7.6-7.8 ( This is the tank Im worryed about ph for the angels.) Now the weird part is... my tap water sits at 8.2-8.4... does water conditioner bring it down. I don;t use ph stuff in the tanks.
On the heater, I don't know how reliable the Aqueon brand is, having never used them. My last heater purchase was Eheim Jager which I believe is very reliable. Prior, I bought three Fluval digital and two of them failed within a year. You might want to start a new thread, in the Freshwater equipment section, on heaters and get more feedback.
On the pH, the rock doesn't seem to be an issue. But how long has it been in this tank? In my experience, calcareous rock will show signs of raising the GH and pH by a month.
On the pH difference between tap and tank, this could be due to a low KH (carbonate hardness, sometimes termed Alkalinity). The natural organic processes in a fish tank will acidify the water and the pH naturally lowers. Regular weekly partial water changes will keep this fairly stable. I would test the pH in the tank prior to each water change; this will let you see if it is moving at all. And always test pH at roughly the same time of the day, e.g., test in the early morning, or late afternoon. This is because the biological processes cause a rise in pH during daylight, and it lowers during darkness. This fluctuation is not harmful, it occurs in natural waters too, and may be anywhere from one to four decimal points, e.g., pH 7.4 in the early morning, to 7.8 in the late afternoon.
