CRS and TDS


Whats too high of TDS for CRS? My tank is at 175 TDS with a PH of 6.4. I've been doing a weekly water change of about 3 gallons (in a 8 gallon tank) with RO water remineralized Fluvia Shrimp and some Azoo Vita and Mineral Plus, but my TDS levels haven't been changing with doing this.

My CRS seem to be doing ok...the large adult survivor I got in the spring (I killed off the other 9 Shrimp I got...oops) is doing well and I got another 10 CRS last month and they seem to be doing ok also from what I can tell...Am I worrying over nothing or should I change what I'm doing?

anything above 200ppm tds would be high.

What are your other parameters? you should be testing for gh/kh as well as ph.

Haven't checked it lately, but I think the last time I did it was 4 gh...I was having a hell of a time finding a test set that would work.

Finally Got my KH tester from Ebay today....I got a KH reading of 1 or 2...it didn't really change color, but I tested water from another aquarium I got and it works ok.

My GH reading was 4....

The Shrimp I got seem to be doing fine, they are almost adult size after 3-4 weeks of having them and doing fine from what I can tell.

Every time you are remineralizing your water you are adding TDS to it. Drop the amount of remineralizer down, test the TDS on the RO water before you put it in the tank. I'm also going to guess 'Mineral plus' is shooting your TDS up too but I've never used it. I've been trying to drop the GH/KH and TDS on a tank of mine so I've been doing .5 ml of Fluval Shrimp Minerals to one gallon of RO. Gives me a TDS of about 60 and a GH of 2 (KH 0). I've done 3-20% changes in the last week and a half and it's gotten my GH down to 7 from 10, KH down to 4 from 6, and TDS down from 180 to 147. I've added straight RO to the tank by 1 gallon (it's a 12 gallon tank) with no remineralizer to drop levels and all the shrimp have been fine and the levels come down of course faster by doing that. I wouldn't do large amounts like that personally, that's less than 10% of my water volume.

Not trying to thread jack, but what specifically would I need to search for on ebay for the slow water pump. Could not find it initially. Thanks

There are all kinds of pumps you can use. Tom's Aqua Lifter is a good one, though slow.

Or you can get a submersible pump to attach tubing to.
