Just trying to figure out optimum dKH for the L134

You can see the range of pH and conductivity values (100ppm TDS is ~ 140 microS).

Darren, are the figures in that image measured in ppm? I'm getting confused

Just a little experiment. I got a 2 litre container and filled it with RoDi and water tested TDS, it was zero. I added the correct volume of 'seachem replenish' to the water and gave it a good swirl. TDS was 117 and pH 7.1. Does the replenish put enough minerals in the water to give my pH meter an ...

[/quote] This is a phosphate based pH buffer, you can use Na2HPO4 (base) and NaH2PO4 (acid) to create a solution that has a stable pH. You don't need the buffer, if you have hard tap water (with CaCO3 "limestone" hardness) you can just cut your RO water with a small amount of tap to give ~100 ppm ...

It is almost impossible for 100% ro/di to have a pH of 8.2. You would have to have some others things in the tank to cause that. But if you test 100% ro/di from a properly working unit, you should get close to 0 TDS and a pH of 7.0 or less. Almost anything you add to the water will increase TDS. I ...

Hi everyone, Just having a few teething issues. My main goal is to breed an L134 I've filled up my 200L tank with Ro/Di. The pH is 8.2 and TDS is 0. I've used seachems 'neutral regulator' to bring the pH down but it's increasing the TDS. Currently pH is 7.4 and TDS is 76. I was planning on using ...

So I ran a few TDS tests today as my tank water was over 300 when I filled it up yesterday with 12 hours of cycling Originally 2/3 full of Ro/Di and the rest with tap water at 500 TDS so it should have been around 150. Only things I added To the tank were brand new seachem matrix and used noodles. I ...

Thank you

Great insite thanks Teresa!!

It's a learning curve but it's fun.

Being a reefer I have access to controlled flow pumps, I might put one in and have a play with different flow rates

Thanks Plecconut,

Feel free to elaborate on the other areas of conditioning.

What plecos are you breeding in hard water?

The tank is 2/3 full of ro/di at the moment. My tap water TDS is around the 500 mark, I think our water here is recycled and my ro water has a TDS of 30. What do you recommend I do from here? I don't have any salts nor would I know where to get them from? I've never heard of them! You should not ...

Do you know what the 500ppm in your tapwater consists of? e.g. is it carbonates, nitrates, etc? Can you check with your local water supplier - in the UK our supplier is obliged to to provide details online of the water chemistry. For example, if I go to this web page and put in my postcode M41 5RD ...

Should add that I live in Australia

I might start with L138 instead of L333

Thanks mol_PMB,

I have an Ro/Di unit that I was planning on filling the tank up with. The TDS is 0. Would that be ideal or too 'Pure'?

Hi everyone,

Just starting out and about to purchase a breeding pair of L333.

A few questions:

1. What is mS an abriviation of? Something to do with water quality.

2. What is considered 'very soft' water?

Thanks in advance
