TDS Pens

Recommended Posts

Brentwillmers

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.

      White bloom is usually bacterial bloom. I'm especially enclined to diagnose that, considering this happened just after you added some Bacter AE. I don't think this is something crtical, but I understand it can be annoying. Try again a partial water change. If you can, vaccuum the substrate, add Mosura BT-9 if you can find some, or live bacterias such as Bio Nitrivec.
      This problem can clear itself after a more or less long time. In my case, it took 2 weeks in one of my tanks. In another tank, I had to use an UV filter. my .02

      Hi, I am a newbie to shrimp keeping and I have come here for some stability in information as to looking around the information of various fish forums vary so much. Some say RCS are easy and will thrive in the same parameters as community fish others will say a great deal more care and closer parameter adjustment. All confusing. So I am hoping to get advice that I can work with. I have on order and should hopefully be delivered this week a custom 25cm cube tank (about 10 gal). I have a sponge filter and air pump as well as a heater. My plan is for a planted tank for my red cherries and hopefully some tank mates but I would like them to breed. My water is classed as ‘Moderately Hard’ GHd 9.84 pH7.25 as per suppler analysis.  Talk of using a TDS pen. I can easily order one, but should we not be aware of what constitutes the dissolved solids or does not that matter? Light for the new tank, 6500K or 8000K which would be best for my shrimp to stand out. I keep going on line to order one or the other and end up not ordering anything. Substrate for both shrimp and plants. All I am sure of is I would like it as close to black as possible. The plants I intend would be Java Moss, Java Fern and Anubias nana petite possible water sprite as that can float and go in the substrate. I welcome any suggestions and I will probably have more myself. I am in no hurry to add livestock . Thanks

      i have a 225ltr tank which as been running since early November, planted, ph 6.2 temp 22.8 tds 170, i put the first lot of shrimp in early january not had any problems, molting as normal and a few berried. a week ago i put a scoop of bactor AE in and just after that a white mist or bloom appeared in the tank, partial water changes have done nothing to help, all shrimp are fine and water is at the right parameters , anyone have any ideas what this could be?, the filter system is a fluval 306 external, i also have an oxydator, and i dont have anything in the tank thats breaking down cheers richie

      I ended up organising a group buy from Kens Fish in the USA. I can't find a cheap local source unfortunately.
