Parameter craziness

Recommended Posts


So I tested my water today for the first time in ages in preparation for selling some shrimp.  I have been very lazy in the last few months with my testing (apart from EC) as my Taiwan Bees and their hybrid buddies have been breeding non-stop and there are plenty of babies/juvies at all times in the tank, an no noticeable deaths.  So I thought all was well, but now I'm feeling very very uneasy.

My current parameters are:

EC: 352 (slightly high but not disastrous)
Ammonia: 0 (hurray)
GH: 4 (low but ok)
KH: 4 (Um, I prefer 0-2)
Ph: 7.6 (or higher, my test kit only goes up to that.  BAD)
Nitrates: 40 (??@#$#@!!!)

The additives/chemicals I currently use in my tank are:
ADA Brighty K
ADA Green Brighty Step 3
1 x IAL (which was added last week)

I do a 10% water change every week with RO, and also have a CO2 injection system running at about 1 bubble per second (e.g. pretty low).

From checking my historical test data, the Ph and EC started creeping up after I started using the Biozyme and BetaG, I used to have to add stuff to the RO water before adding it to the tank to avoid a massive EC drop but that's no longer the case.  I had been fertilising more regularly recently to try and encourage plant growth to eradicate a BGA outbreak, but I didn't think I'd added anywhere near enough to raise the nitrates that high.   

I know it's possible that my shrimp are acclimatized and thriving in this environment, however I can't help but worry now and would like to get the parameters back down to something a little more suitable for their poor fragile dispositions (e.g. get the EC back to well under 350, the Ph down to 6.6, the nitrates under 20 and the Kh at 0-2).  However, it's also been my mantra with this tank that changes are made very slowly to avoid knee jerk reactions ending in disaster.  

I'm due to do another water change tomorrow and will test again after that, but other suggestions are welcome!

Hello @Jo

Did you end up testing your WP again? How did it go?

Um it makes sense to leave it if everything is breeding and shrimp looks fine. You changing the parameters back to "how" they meant to be might not end very well. If you insist on changing i would do it slow

      ph dropping is part of the nitrogen cycle. That means the bacteria is doing it's thing. A water change with higher pH water is necessary now to avoid the cycle stalling. The prawn growing fur is also normal, as it is decomposing, and fungi are starting to break it down. Let the biofilm grow as that will be part of the shrimp's diet once you add some in. If it's hindering your view, scrape it off the front glass only, but don't syphon it out. The dislodged biofilm from the front glass will settle somewhere else in the tank.

      Its good to hear that the fur growing on the shrimp is 'normal', I may leave them in until thursdays usual maintenance day then. Todays readings are as before nitrate 25, ammonia and nitrite 0! I could get someone to get me some duckweek from the lake but I remember how hard it was to get rid of it before, so am a bit reluctant to go that route, but it should bring the nitrates down a bit??? You should leave the biofilm in the tank, the shrimps will thoroughly enjoy that when they get into that tank. Simon

      As you are aiming for TDS150 and the tank is near that now at 147 you just make the new water up to near as you can TDS150 and if you keep topping up with pure RO water between changes this would be the normal routine from now. Getting a new TDS meter was the right thing to do as they are cheap enough and hopefully it will be more accurate? As someone said before, you can get a rough idea of whether the TDS reading is right by doing a GH test as using RO water and remineraliser those figures should be related. Probably best to test some mineralised water before you put it in the tank though! Good that you haven't lost any more shrimps, hopefully that continues and all should be straight forward now. Simon

      Thank you. Yeah they are great quality discus of German lineage. Due to family and young kids, I was not able to devote my time to them as much as I would like to so I have since sold them back to the person who sold them to me in the first place. He has been a discus breeder for many years so I know he will look after them well and keep their progeny going within Australia. Thank you. This rack is still running but I am planning to strip it all down, move it to the garage and set it all up again.

      Okay so I haven't done a water change in weeks because I thought the TDS needed to get closer to 150 before changing and my TDS meter continually kept reading 108 to 114. Sho I went and bought a new TDS meter and it's different from my old one.  The new one vs my old one: my water in tank 147 vs 103, water using the correct salty shrimp mix to RO water 88 vs 66. So I'm going with the reading on my new TDS meter.  So it's time for a water change.  Should I replace the water with the 88 TDS or put some more mix in until it's above 100 (since CRS parameters should be 100-200)? Thanks again everyone
