Water Change and Reminerizing

I have got some questions regarding how i do my water change and how do i reminerize. In this short post i’ll share with you how i do mine the easy and effective way. There are other ways to do water change, i just want to ensure they are the quickest possible methodology so i can enjoy my shrimps more.

The main reason for doing water change is really about remove nitrates in the water

With the filtration that i’m using a sophisticated hang on back which works very well after trying many other brands like Fluval, Ehiem, Gex, etc. http://www.totto.co.jp/en/test.php

This filter have the ability to remove nitrates from the water column as indicated by the Tokyo Institute of Technology (https://www.titech.ac.jp/english/). The correlation between lowering of pH caused by Nitrate is usually unspoken of causing lots of shrimp death unknowingly. Conventional filters don’t have the ability to remove nitrates and hence water change is required to remove it. Hence, it means if your filter don’t have the ability to remove nitrates than it is important that your water changes are done religiously to ensure the front end process such as feeding etc are still kept up because the entire process from feeding to water change are all interlinked and cannot be separated individually to be resolved when a problem arises.

During water change, what i’ll do is remove water from the tank and add in TDS 0 water directly into the tank. After it is filled, i’ll reminerize it to 85-90 TDS using Hwa Reminerizer. I normally change 5-10% of the tank water depending on the bioload and tank volume. For my denser tank with more shrimp, i’ll do up to 25-30% water change weekly. This will help reduce the amount of nitrate in the water. I have used all sorts of filter, from hang on, canister, sponge etc, even the best filter still require water change. So don’t skip that water change and make sure the water change is reminerized with a good reminerizer because there are many in the market where the GH and TDS value doesn’t hit the mark.

The reminerizer for example i’m using will get GH 2.x at TDS 85 and GH3 at TDS 90. Some reminerizer may only achieve GH 3 at TDS 120. So it’s important to know what we are adding in the tank. For my case i want to achieve at GH of 2-3 at TDS 85-90.

Happy Holidays!
