RO water to planted 180 gallon Discus tank
Hi
Im pretty new to discus, i live in Sweden and there is not a lot of information about this question im trying to find out more about.
Sorry if my speling is bad
I got my first 10 discus in june this year and have been reading about discus approx 1,5 years befor having them in my aquarium.
I have this water parameters from my tap, and i have water from my own well.
PH 7,5 After going trrogh several filters, its actualy acid 6,8 but wont work good with the coper pipes in my house.
KH 6.0
Gh 5.0
Cu 0.3
PPM 156
ms/cm 243
PO4 1.8 and beyond limits over that
SIO2 6.0 and beyond limits over that
You could say this is prety good values for discus tap water?
The problem is that i have a planted discus tank with botom substrate.
The discus i have is 5 cobolt blue and one Brown Curilenquer VF3 I have hade 1 more cobolt blue and three Brown Curilenquer VF3 but unfortnelety the died .
The size of my discus is about 4-5" (12cm)
The temperaur is around 83 Farenheigt, 28,5 Celsius, i have two canisterfilters.
SunSun HW-404B Aquarium External Canister Filter 2000l/h with 9W CUV, and they are setup like the pound guro set up his sunsun filter but with aother filtermedia. i also use spreader tubes to have a calm surface movement in the tank.
The waterparameters in the tank is
PH 7,5
KH 7.0
Gh 8.0
Cu 0.2
PPM 310
ms/cm 484
PO4 1.8 and beyond limits over that, a lot of alges covering my plants
SIO2 6.0 and beyond limits over that, a lot of alges covering my plants
I have prawns in aouther tanks and the only survives in RO water.
So i tryid to have aging RO water with same minerals as to my neocaridinas. SALTY SHRIMP SHRIMP MINERAL GH/KH+ you could buy the same minerals with a discus on the front =) but that is only Gh+ and not GH/KH+.
Then i get this values in my circulated bin
After 24 hoaurs.
PH 7,4
KH 3.0
Gh 7.0
Cu 0.0
PPM 200
ms/cm 312
PO4 0.0 Proberly less algy problems
SIO2 0.0 Proberly less algy problems
I tryed with smalet amount of minerals and hade this out in the bin
After agin for 5 hours
PH 7.2
KH 2.0
Gh 5.0
Cu 0.0
PPM 140
ms/cm 218
PO4 0.0 Proberly less algy problems
SIO2 0.0 Proberly less algy problems
I have sean that you only need to use RO water when you have spawns or when trying to get discus to fry of.
Or when you keep wild discus. And its alot of talking about what PPM value to have when you are having fryes, I could not find any info on PPM for discus that is about 4-5" (12cm) in size.
My problem is that my PH in the tapp is not consistent bethween 6.8-7.5 and the fact that i have high values of POS4 and SIO2 and also Cu of 0.3-0-8.
Pleas help me with this problem or advise me what to do?
I have been reading throug 30 pages in the Forum->Main Discus Topics->Water Works and have hade a lot more information on how to keep fry and eggs .
I would also like to bye more discus to the aquarium since its so big and one off the bigest discus likes to show he is the master in the tank.
But i need to have good water parameters first, dont whont more to die.
This is the tank

KH 2.0
Gh 5.0
Cu 0.0
PPM 140
ms/cm 218
PO4 0.0 Proberly less algy problems
