Edward-I just finished the medication cycle and did a 50% wtr change. My tank specs are:
kh-3
gh-6
Kno3-15
Po4-1.0
TDS-146

Should I restart the PPS with the standard solution. If so how much is good to go with for an 80 gallon? ALso, similarly how much TE solution should I dose. Should I be dosing MG or CA. Maybe not as I have 1/3 Onxy sand, and my GH never goes below 5. I am having a hard time finding a good Ca source as well. I just bought a marine suppliment of calcium chloride, but I dont know the percentage and its a liquid. Thanks for your help in advance.

Hi chiahead,

dose DS Discus Solution daily 6ml.
Don't worry about the Ca and Mg until you get the Ca test kit. You don't want to over fertilize. You can dose 1ml of TE for now. Keep your CO2 30 - 40 ppm, the CO2 table is in this Fertilizer forum FAQ. Do you use any pH buffers?
PM me if you would like our new PPS Analysis xls program for easy data keeping. It is a standardized fertilizing spreadsheet for PPS users we share.

during the medication I was dosing about 5 ml of DS solution and the leaves started to show signs of Ca deficiency(curly, distorted new growth), so I dropped it down to 2 ml daily. Ofcourse that could of been due to the meds. I did buy a Ca test today it read 30 ppm or so. I need to restest after the wtr change though. I do not use any ph buffers, arent they bad for planted tanks as many are phosphate buffers?

Hi chiahead,

not sure what Ca test kit you got. With the Hagen kit we use 2x more water, in 10ml we get better resolution. One drop in 10ml is 10 ppm. Good range is 20 to 30 ppm.
If your GH is 6 and Ca is 30 ppm then your Mg is 8 ppm. No need to dose Ca or Mg. You are doing fine. Test before water change and make notes.
It is good not to use pH buffers as they make it impossible to determine CO2 concentrations.
DS Discus Solution does not cause curly distorted growth.

Is the PPS spreadsheet available anywhere to download? I just recently started the system, look forward to seeing the results!

hi Edward,

I bought a Ca test from Salifert. I just tested after my water change yesturday and got about 15. The test isnt very accurate at low levels. Looks like the Ca test was designed for saltwater which makes sense. Well, the deficiency started during the mediaction so it may be that. It did look alot like a calcium def though. Leaves curly, distorted new growth. Leaves almost transsparent, whitish or very light green. My ammania seneglesis especially curled its leaves. I will wait and see if they start to pick back up. Should I dose the DS for a week or be testing daily until I get the amounts nailed in? Also, when should I change at what values No4=10 and Po4=1.0???

Hi SAWALLACE,

the file can be downloaded here: PPS.Analysis.20041231.xls

Please rename the file to SAWALLACE.PPS.Analysis.20041231.xls
If you need help, email your xls file to PerpetualPreservationSystem@hotmail.com

Anyone interested can do the same.
Thank you,
Edward

this appears to be an excel program only. I do not have excel, oh well.

.xls files are Excel. This spreadsheet requires Excel 2002 or better to work properly.
