Got these test strips at lowes for the giggles (90% off, so I figured why not). I don't know if they are bad, or if my tanks and ponds don't require the work I thought they did @.@ image Left to right: 6 gallon, 10 gallon, 20 gallon, 65 gallon, 150 gallon. The tests: image No ammonia, and useless alakaniity and hardness, but whatever. How the tests appear on the label is how they appear on the strips (so, top to bottom). All tanks show 0 nitrate, exept the 20 long, which is kind of weird. Why would it be out of whack? It's cleaned every 2 weeks (plants enable me to slack off) and feeding is strictly monitored. It just barely shows a hint of pink though, so whatever, I guess. Lil' extra water change will make it all better. All tanks, even the ponds, show 0 nitrite. It's to be expected from the tanks, as they are packed full of plants, but the ponds have a single lily, which have gone dormant for the winter, and honestly, I hardly ever get around to water changes on them (in my defense, it's been cold lately, so feeding has been reduced, and many times they don't need to be fed these days due to the cold temps, and it's been raining a lot, so why give them yucky city water when they can have rain water). However, the algea in both are rediculous. I can't see the fish unless they are near the surface. Perhaps that's why show 0....? Hardness is an even 150 in all of them. Don't know anything about hardness, so no comments there. Alkalinity is all over the board, and the tie dye effect on them doesn't do me any good at all. Besides that, it's not something i care about or know about. PH is a little crazy as well, coming in at 5.5 (the lowest possible reading) or lower in the 6 and 20 gallons, 6.5-7 on the 10, 7 on the 65 gallon pond (recently got a large water change in an attempt to get out the dang algea, and then the day after it drained itself, so it got another larger water change. So, this pond is basically all city water at the momment), and 5.5-6.5 on the 150. The 6 and 20 long get mass amounts of Flourish comp due to the plants. Does that have any bearing on the low pH? The 150 gallon pond is all rain water, so that explains that. Anyway, I was just playing around with my new strips. Curiosity wanted to know why they were on clearence, and if they were any good (as good ad strips can be).
