Hi,
unfortunately I do not have enough english words to say "thank you" in enough different ways. ;-)
cbul2,
the clam-tank and also the 2 in the cellar are made of glass and 100x50x50cm big.
There is an overflow box with two bottom drillings (overflow/emergency overflow)
for 32mm pipes and a small Tunze pump for water movement.
The overflow box is only 40cm high to keep the waterlevel lower.
Thats safer, when messing around with the frags.
The tanks rest on 2x2cm Aluminium frame with metal-core joints.
The tanks opposite (not to be seen fully on the pics) are 100*3l boxes with young, growing
Betta splendens (freshwater), which I bread. (Crowntails and Halfmoons for those, who know
what I am talking about

). 100 Boxes, because the fighting-fish males would kill each other if not raised in a different box.
Baros,
thank you. Yes, thats enough fish. There are too many coral for larger fish ;-).
Yes, I now have 4 of the Harton hose-pumps (industrial/lab use) and am very glad
with them. Fauna Marin is thinking about selling similar pumps in the near future in their
"Ultra" line, if I understood right.
They really dose exactly the same volume each time.
The AMs unfortunately never did what they should :-(.
aspinn,
well, yes ;-)
martinezhbr,
huh, 13 pages... Think I should also read through them again, thats quite a long time ago.
dn100,
the calcium reactor question is really easy to be answered: because it is there.
Else I would have to buy some dosage-pumps.
I started my last maintank with this Schuran reactor and coral also grew well,
using artificial Ca-filling with some Mg-additions and pH-control.
I will check Ca/Mg/KH weekly as always and correct them with "Balling". That should work.
Btw, the Schuran skimmer on the floor is also the one from my prior maintaink.
edit: nearly forgot the macroalgae. They are still there, but currently the partition is
only half filled with algae. Some Hermits are living there now(don't know where they are from

.
