Zoone

This is the new bulbs, the pictures are taken with white balance set to cloudy sky, but i still don’t think the colors on the picture reflects the real thing.

I_MG_3570.jpg is AB10000
I_MG_3581.jpg is Giesemannn Tropic

It feels like the new bulbs give a lot more light, this could be two reasons for this, the AB10000 bulbs are quite old now and the fact that the new ones have more light in the green and yellow part of the spectrum which the human eye are more sensitive to. One little confirmation of the extended light of the new bulbs is that the Tropic picture was exposed with 1.3EV less.

MH bulbs is known to change color temperature especially the first time while burn in process, so i will have to wait and se what happens.

This is an old picture but i am throwing it in anyway as i have not published any pictures here yet.

This is my entry to the APC International Aquaplant Layout Contest.

Aquatic Plant Central

Those of you who run IE will have to live with the visual problems on this site, it’s mainly disappearing text which apers again after scrolling up and down.

This is due to problems in IE but it is probably solvable by workaround, but it will take some time (this is not from where the income comes from).

Hang in there, it is most probably solvable.

This is the looks of my technical equipment for the moment

6kg CO2 bottle with regulator and needle valve, in an carton tube to hide it.

The parts in the aquarium cabinet:
Self designed and self made CO2 reactor (I’m going to make an entry about this later).
Electrical unit with sockets and timer.
Double nutrition pump, the containers are behind the filter canister.
CO2 controller, it does not show the right value but it keeps it steady.
Eheim 2128 proII thermo, thermo is because i wanted as few parts in the tank as possible.
The filter canister also hides a 5W UV-filter, a bit to low efficiency but anyway.

I use this shortcut quite often to sort out the CO2 level instead of different tables, it seems very well done and seems trustworthy.

The major water change for the nutrition uptake with no food for the fishes is now done.

The values became:
0ppm NO3
0ppm PO4
0ppm Fe

KH 2
GH 2

According to this, it should be a good starting point for the test as all relevant values were zero.

Finally i have a working automatic nutrition dosing system.

This is fairly the levels i dose:
5 ppm NO3
0.75 ppm PO4
5 ppm K
0.1 ppm Fe

One week of dosing should only be able to give these maximum levels (if the plants uptake is zero): 
35 ppm NO3
5.25 ppm PO4
35 ppm K
0.7 ppm Fe

One week ago i made several massive water changes to set all levels to zero, this was mainly to be able to check the auto dosing.

This is the levels i got one week later:
50ppm NO3
5ppm PO4
0.2ppm Fe

Ph 6.0-6.1
KH 1.25
GH 4

Calculated CO2 about 30ppm

A quick check at the Fe level tells me that the nutrition uptake is quite good but the NO3 and PO4 levels are quite high but this i would guess is because i feed my discuses fairly much.

I’m thinking of doing this test next week, same massive water change but this week i will not feed the fishes i hope this will show what i’m adding and what the food is adding.
