Advantages · It can be used with a small water pump of 120 L per hour or less, it can be used in a small aquarium because it can suppress water temperature rise as much as possible because it is 6 w lamp. Points to remember · Because it is a stainless steel tank, it will be used in freshwater (since the photo of seawater fish is out in the box and it is Aqualium as one of the applications, the manufacturer may be assuming use in sea water, but it is recommended Absent). · 1/4 PT male stainless steel hose nipple and seal tape are required separately in the water inlet / outlet. · Does the thread cutting method be miscellaneous or slightly distorted at the time of welding? It needs some force to screw the hose nipple. If you have an M14 glasses wrench of 45 cm or longer length or a deep socket and a ratchet handle, you think it is an easy victory, but if you do not tighten it tightly until the end you will leak water. Water leaks unless the seal tape is rolled three times in a clockwise direction along the groove of the screw (because it thinks that some people do not know that it is a general aquarist rather than a water taker). · Although it is difficult to raise the temperature, it does not rise, so be careful. Those who are considering Kamihata's sterilization kappa, I think that it is worth considering here as well.
