I have 2x 8' pools at the moment. They are great! Got them each for $15 brand new. They are holding up well so far. My real plan was to use the 18 footer in an experimental design that has absolutely no need for feed input from external sources or at a minimum no feed inputs that cost money (free is okay). Anyway...
Of course, there are many places one may purchase pools and pool-related supplies. However, I would respectfully submit that "you get what you pay for" . . . Consequently, if you're looking to have a pool which may only last one or two seasons (at the most), then purchase a "cheap" pool. However, if you're looking for a GOOD swimming pool, then it would be worth the effort to do some "homework"!
The good quality pools are of 18 foot are starts from $1000 and they are better then other easy installation pools. I also have a above ground pool which is 21 foot which was about $1500. Well intex is the best brand in above ground pools.
well,, the nitrate levels don't really matter, right? just kidding...
What is the max high safe range your nitrates can be at...best way to lower nitrates?
Most test kits don't read above 100-120ppm, so I'd say that's pushing it for most fish's safety. The easiest way to lower nitrates is with a water change. If you have hardy fish like tilapia or goldfish, changing up to 50% of the water would be fine; however, if you have more sensitive fish, stick to 10-20% changes.
If you have an artificial source of light (ie. indoors or greenhouse), induce flowering with an increased day length or change in color (I hear more red wavelenght induces flowering).
