TDS Pens

6 posts in this topic

Hi 

I usually am a google reader and find info on the net. But this one I'm truly stuck with. 

TDS pens. Used to measure total dissolved solids/organics etc. my question is what benefit is it when using RO or distilled water. The organic or "dissolved solids" would of been removed so leaving it in a more clean natural state. All those harsh chemicals are removed. 

So if I dose macro/micro's would it be any benefit to me in helping keep my water clean, healthy and full of nutrients.  

I do test all the standard tests + phosphate iron GH/KH 

Thanks

Then you have to read this ...

 

RO water removes the unwanted chemicals, metals, bacteria and algae in tapwater. But Fish and shrimp cannot live in such sterile water devoid of salts.

You need to remineralise the water by adding back Calcium and Magnesium to a level suitable for the type of fish or shrimp you are keeping. How much you add is helped by the use of a TDS meter. The TDS meter will also help you maintain the correct range for your shrimp. And as TDS rises due to fertilisation or waste build up from the tank inhabitants, it can serve as a reminder for a water change.

Thanks Jayc  

i was really unsure on its value towards nutritional water quality. Or range of worth for a heavily planted hi-tec aquarium been dosed with macro's and micro's. 

With shrimp like cherry and CRS, what would you call a suitable TDS value on these pens. I have seen people range their waters from 120-160. Would that be suffice in my case.

Cherries have a wider range they can tolerate - 100 to 200 TDS.

CRS are more sensitive, so stick to a range of around 140 to 160 TDS.

Ordered myself a TDS pen yesterday.

just out of interest. If I don't have a range in between 140 to 160 either up or down. What's the correct way of getting within those values, or is it just water changes and no special treatments. 

Thanks again

Good move. A TDS pen was the best purchase out of all the aquarium accessories I have bought.

I'm assuming you have not read the article yet. If the TDS is under ... add more RO remineralising solution to your change water. Eg if tank TDS is 130, then make new water that is 160.
If TDS is over ... Water change with new, clean water that has been treated with a lower TDS.
If you are only typing of water that has been evaporated then just add pure ro water.

      Hi  has anyone found a trusted method of using fertilizers in planted tanks that require heavy dosing without raising TDS to extream levels. I am finding single doses of micro's or macro's could tip TDS value into the mid to high 300's.  Before I got shrimp I had a religious dosing routine which followed the Tom Barr method of heavy dosing of macros and micros for every day for 6 days and major water change on day 7 to reset your parameters.  The seachem Aquavitro range I found to be the best and have had great success in growing great looking plants, but has its fall backs like raising TDS to high levels.  I am keen to know how others have found the perfect line of ferts Vs TDS

      I would also highly recommend getting a GH/KH test kit so you can determine if GH/KH was an issue.

      Hi@daimen

      So sorry to hear :-(

      Your temp and tds is ok. Its better to keep the temp at 22-24 if possible though. However short periods upwards of 25 may be ok depending on the genetics of the shrimp and how fragile the line is.

      However a pH much above 7 will slowly kill off softwater caridina shrimps I'm afraid. If nothing else then that would explain the losses.


      Will

      Hi all, I have my CRS dead. Have had them for about 3 or 4 months. Filter was cycled in another tank and added when shrimp arrived. They are in a 20L tank with params 7.5 PH temp 23-25 TDS 143. I dont have KH and GH tests. I use rain water and i add micronection powder to water changes. Any help with finding out what happened Thanks Sent from my SM-N920I using Tapatalk
