这个4 stage把 Ph Balancing加在最后一级肯定没有问题。
看你最后一级直径是多少，决定买1/4还是3/8的。估计是1/4的。 |

你可以买tds测试剂试试就知道了。
如果自来水是300，filter以后也就是250，ro大概是30，外面买的水大概是100。
看你这样子可能400都不止了吧。 |

Tests on the jet that landed at the Dallas-Fort Worth airport showed low

No passengers were quarantined.

多的和300多的（http://www.costco.ca/water-filtration-conservation.html），也不知道一般价位要买多少的性价比还可以，大家都是哪里买的啊？有没有好心人给推荐一款？
版上好多牛人都是买了设备自己安装的，俺们都不是handy的人，想问问看有木有人能
推荐一下找哪家公司给安装？如果找人安装的话，是他们有自己品牌的机器，还是我们
需要自己买？

Also, Palasades, Bleith, Foxhall, Glover park...(NW DC) are all good areas,

too. I had a hoya UV($30) and a Hoya CPL ($110) before. they were really
good. But I never had the chance to compare and I didn't really care either.
I read the Tiffen UV filters are really good too in terms of effectiveness
of filtration, not sure about resolution, etc. Looking forward to see your

An airstone is a piece of aquarium furniture, traditionally a piece of
limewood or
porous stone, whose purpose is to gradually diffuse oxygen into the tank,
eliminating
the noise and large bubbles of conventional air filtration systems, and
providing
other benefits to the health of the fish. Airstones are sold in a very wide
variety
of shapes, sizes, and levels of coarseness--from extremely rough, producing

发帖数: 5457 | 43 ph 6.8不足以对锦鲤有那么大的危害。即使对很多热带鱼或者cichlid都不足以引起大
的问题。
你的这个主要是没有filtration和水流，长时间一个30g的缸，封闭的环境，像锦鲤这
样能吃能拉的鱼，水质很快就变坏了。对于petfish，amonia和nitrate/nitrite比pH更
重要，KH更不用考虑了，除了一些african cichlids，或者breed特殊的american
cichlids需要考虑到KH，鲤鱼这样的皮实货或者大多数鱼，没有必要考虑。
只要是一个cycle好的老缸，有足够的有益菌群，加水除氯，大多数鱼都不会有问题。
不需要考虑那么细致。 |

this tank and fish for years and I did test all the water parameters last
night.
on a side note and i dont know this until now, KOIs like a slight higher ph
and 6.8 is the low end of their tolerence. a ph of 6.8 coupled with low kh
will start to burn their skin. i never had cichild myself, but most tropical
fishes like tetra or guppy actually like a slight lower ph. so 6.8 is
probably just fine for them. Therefore, limes... 阅读全帖 |

给这个之前摔断把手的虾铲续个弦
事实证明这个东西比我估计的费时间， 主要是要考虑把剩下的那块塑料也包进去， 样
式也老是不满意，做图花了差不多2个小时
打印时间5小时30分钟，实心结构的哦
拿出来稍稍打磨，去支撑，对齐，电钻钻4个小孔，4个螺丝固定。完工
好像有点太粗了
机器只能打ABS，破解slicer以后能改温度，不过PLA去支撑太蛋疼了，HIPS太贵,还是
ABS比较接地气。
abs 还是注意通风比较好。不光是味，我测了下PM 2.5 也有点变化。
不过这台机器内置 HEPA air filtration system，而且是丢洗衣房里，应该还好
pla的打出来的漂亮， 不过太脆了。
up的机器打abs去支撑还是比较方便的，手撕就行
还有就是pla实在不耐高温，拿来做渔具夏天放车里会悲剧的
这个机器有冷却风扇，打大件的时候关上，防止翘边，打小件或者overhang多的件的时
候打开，要不向下的面比较粗糙 |
