pHマイナス

商品説明
硫酸水素ナトリウムは一般的な公共プールでも用いられている
人体に安全なpH・KH降下剤です。
落札された方々にもたびたびご好評をいただいております。


アクアリウムで昔から用いられていた硝酸や塩酸などは
近年防犯上の理由から一般での入手は困難になりつつあり、
また市販のpH降下剤は継続的に使用するには高コストになってしまいます。


低pHを好む魚種の飼育・繁殖や水草の育成をなされる方が
より低コストで気兼ねなく換水できるようお分けさせて頂いております。
実際に私も使用して魚やエビなどに害が無いことを確認済みです。
落札された方々にもたびたびご好評をいただいております。





本製品の使用量の一例として
pH6.5 KH4 GH5の水道水のpHを1下げ、pH5.5にする場合。
10Lあたり約1.2gが必要になります。


通常の範囲の水道水のpHを1下げる場合
硫酸水素ナトリウム100gで 0.5t~1t程度
硫酸水素ナトリウム500gで 2,5t~5t程度
にご使用になれるかと思います。


※ご参考までに、上記と同条件でテトラpH/KHマイナスを使用した場合
500mlボトル一本で約0.83tになります。




使用量は通常の水質であれば10Lあたり1gから2g量を目安に調整してください。

ご使用の際は本品100gを500mlの精製水(もしくは水道水)で希釈し、
10Lあたり5ml~10mlの使用を目安としてご使用頂けると便利です。

注意事項
・本品は「テトラpH/KHマイナス」等と同様に、KH値(アルカリ度)を下げることでpH値を下げ、
 飼育水を酸性に傾ける製品です。


・pH降下剤全般に共通ですが、GH値は殆ど下がりません。


 投入するにつれ、まずKHが下がり始め、KHが0になって後、初めてpHが下がり始めます。
 (KHが0になるまでpHは変化しません)
  KH値が0になった後は、ごく少量の投入でもpH値は大きく変動します。



・換水の際の新水にご使用下さい。水槽への直接の投与は、
 濃い溶液が生体に触れた場合、ダメージを与える恐れがあります。



・使用例はあくまでも一例です。水道水の水質は全国で異なりますので
 必ずpHテスターなどの水質測定具と一緒にご使用ください。



・水溶液は酸性ですので、水に溶かした状態で長期間保管する場合は
 ガラス瓶等の変質しない容器を使用した方が良いかと思います。

--------------------------------------------------------------------------------
ペットボトルに水溶液を長期間保存した場合、
ペット樹脂が加水分解され有害なエチレングリコールが溶けだす可能性が考えられたため、
ガラス容器の使用を勧めさせて頂いております。

(ただエチレングリコールの毒性は、
1リットルあたり1~10gという非常に多い量でなければ発現せず。
そのうえ容易にバクテリアによって分解されるため、
ペット樹脂が加水分解して、水生生物に悪影響を及ぼす可能性は非常に低いと思います)

実際にペットボトル保管でも、特に問題は起こりませんでしたが、
万全を期すため敢えて変質しない容器の使用を勧めさせて頂いております。
--------------------------------------------------------------------------------

その他
ご希望の方には、こちらの商品説明文と同様の取扱説明書を同封して発送いたします。
ご落札後に取引ナビより、説明書の添付を希望する旨お知らせください。

Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters).

3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.
