Hello,
I have face with serious problem and I need your help guys.
Planted Tank 125*50*50 (82 gal)
Light ATI Sanpower 6*54 t5:step method
2 hour - 2*54
6hours 4*54
2 hours 2*54
Ferts maintained levels
NO3 15
PO4 0.8
+Micro (Fluorish Trace)+Fe (EDTA)
Water
Using mixing RO withTap water 1/5. - this gave me КН 2,5-3. My Ro water have Ph 5.7 and when made 40% o weekly changes - Ph in my tank was aprox 5,9.
Before:
I used Inline CO2 reactor (installed after canister filter output and before entering into tank) CO2 injection has been controlled by PH Probe and maintained PH 6,0-6,1 - I was using this system about half year.
But my DC (with test solution from Dennerle) was always mm' not light green and not dark green, so i suggested that it was not 30 ppm of CO2. In addition, in view of some of my plants, it was clear that a greater amount of Co2 is needed.
So I radically change CO2 injection method -I remove my inline reactor and install DIY diffuser (here the link you can look and compare it with dennerle or ada diffusers http://video.yandex.ru/users/arryl77/view/3/)
Also here you can look how its installed http://video.yandex.ru/users/arryl77/view/1/.
Intensity 3 bps (bubbles checked via 5 mm standart oxygen tube)
Time. Start at 9-00 (1 hour before light on) and end at 19-00 (1 hour before light off)
No additional aeration, only hanged filter which work 24/7 (but its get really slow surface agitation)
Ph probe is simply to monitor Ph level
Results DC - is green at morning and bright green around 13-00.
Ph fluctuation 6.3 at morning and 5,5 at evening.
Fish for the most part did not show signs of oxygen starvation.
But I noticed that even though the fact that the appearance of the plants was much better, perling was markedly less than before , I was rarely noticed my shrimp and found unhealthy behavior of some fishes. SAE: became like faded. Aslo i found some dead fishes (only 1 R.heteromorpha).
Also the second week after the next WC I noticed a slight clouding of the water.All fish ( I have about 50 P.innesi 50 R.heteromorpha 20 Oto and some amount of C.Japonica)
Then decided to check my Ph probe and its was SHOCK. My real Ph fluctuations was from 4,8 to 5,6. Ind its look that it was from the beginning of using this injection method.
So now I need good solution what to do.
Actually my Plants is happy with such amount of co2 View attachment 1112 and according to DC its bright green (30-35mg) (for example friend of mine use the same DC solution in his tank with ADA substrate KH3 same tap+ro mixing etc - and have even yellow color)
So CO2 concentration is quite good, but due to my RO has lo PH and I add CO2 during 7 hours with 3bps intensity) Ph drop very fast and night rice is aprox 0.5-0.6.
So may be its possible to rise ph (for example adding something to Ro water). Decreasing CO2 injection rate is not a sloution cause when I tried 2 or 2,3 bps, the DC was not bright green.
Also can i connect clouding of water with mmm.. may be some bacteria died due to low ph. etc.
Sorry for long and muddled message. - but I really need the urgent solution.....
