Review on Fluval A7551 CO2 Indicator Kit by Patricia Mendoza

only got the item today so I don't have much info on the accuracy or anything but thought I'd jump in and tell the world say difficulties that I have already had to go through with this product. Firstly, the sticker that came with it didn't have any glue so I had to tape it down - it looks crappy. Also, I'm concerned my fish might knock it off as I have some fairly large 4-5 inch fish that go crazy when fed. The suction cup doesn't attach well to the display, so I'm concerned. They could improve the design if it was actually attached to the turn signal. However, this would result in not being able to replace the suction cup when it goes bad. For the price of the product I don't think it would do much There's a difference just buying a new one when it's old. But here is a big fight. It took me 30 minutes to take the damn cap off! No part of me can physically grip the cap well enough to remove it, and even the handles I use to open the bottle didn't help. I ended up prying it open around the edges by snapping my nails and then prying it all the way with a thin piece of metal. Not to mention the cap was difficult to put on, plus it's too tight and in the photo you can see the o-ring stretching and flattening out when you put the cap back on because it's too tight. the fight. I don't want to go through this again, but I need to change the indicator fluid in 3-4 weeks!
