Winter Biological Packaging(겨울철 생물 포장) When we send biological things such as water plant, shrimp or fish, we are really nervous about the death of them. In my case, I pay more attention to the sending of the fish, shrimps and aquarium plants than I really think. 흔히 겨울에 택배를 보내게 되면 정말로 신경이 많이 쓰인다. 혹시나 생물이 죽을까? 필자 같은 경우, 물고기, 새우 그리고 수초를 분양하면서 정말로 생각보다 많이 신경을 쓴다. It is because when I kept them I ha..

Water Parameters(2): TDS (수질 변수: 총용존 고형물 이해하기) Total Dissolved Solids (TDS): 총용존 고형물 TDS means "total amount of solids dissolved in water".1. Normally, beneficial minerals in the water such as calcium, magnesium, chlorine, and sulfate ions are dissolved. The instrument that measures how much those solid are dissolved is a TDS meter. TDS란: "물속에 녹아 있는 고형물질의 총량"을 의미한다.1. 대체로 물속에 있는 유익한 미네랄 성분인 칼슘, ..

Removing algae and Cyanobacteria with Peroxide (과산화수소로 이끼(조류)및 시아노제거) Dosing Peroxide (H2O2)is another interesting way to control/kill algae. Dosing Peroxide has proven to be very effective against Cyanobacteria, Black Brush Algae, and Green Hair Algae but like any quick fix, this method won't solve the root cause of algae in your aquarium. I recommend dosing Peroxide in conjunction with steps t..

Algae Control With Flourish Excel(플로엑셀로 이끼 제거하기) Flourish Excel is a source of organic carbon that can be used as an alternative to CO2 injection. Though not marketed as such, Flourish Excel has proven to be very effective at controlling algae when used at dosage above the recommended levels. In this article, we will have a look at 3 different ways of using Flourish Excel for algae control: the ..

White or Grayish Water, Cloudiness in an aquarium tank(백탁) Gravel Residue - If the water is cloudy immediately, or within an hour or two of filling the tank, it's probably due to insufficiently washed gravel. Drain the tank and rinse the gravel until the water runs clear. That should resolve the problem. 자갈 잔여물 - 만약 수조를 가득채우고 한 두시간 안에 물이 바로 흐려진다면, 그것은 아마도 자갈을 덜 세척해서다. 수조에 물을 빼내고 깨끗한 물이 나올 때까지 씻어..

The Aquarium Nitrogen Cycle수조 질소 사이클 The aquarium nitrogen cycle information presented below may be rather boring to most people, but it is absolutely essential to understand this process if you want to be successful at keeping fish! Some call it the biological cycle, the nitrification process, new tank syndrome or even the start-up cycle. They all are referring to the same cycle - The Nitrogen ..

Water Parameters: Understanding pH, GH, KH, CO2, and others수질 변수: pH, GH, KH, CO2 등 이해하기 Water chemistry is one of the most misunderstood areas of shrimp-keeping, especially when it comes the pH, GH/KH, and the KH-pH relationship.The GH/KH water test kit is often the most neglected kit, and, hence, arguably, the most neglected part of the water chemistry.To get started let's talk briefly about w..

DIY CO2 generator & principle (자작이탄 만들기 & 원리) Although CO2 is an option for fishkeeping, almost essential!Mainly, Carbon dioxide is an essential component for plants to make photosynthesis. 물생활에 선택이지만 거의 필수적인 이산화탄소!즉, 이산화탄소라는 것은 수초들이 광합성 작용을 위해 필요한 필수성분이다. ★ Photosynthesis: Carbon dioxide + Water --- by Light ----> Glucose + Oxygen + slightly water (view of Bioscience)★ 광합성 작용: 이산화탄소 + 물 ---- 빛에..
