Thanks,
Luiz,
I think that one of the bigger problems, regarding large tanks, is the humidity.
The temperature range, where I live is from a max of about 35-40 degree centigrade in summer
to -20 C in winter, with relatively long periods of wet air combined with low temperatures.
In summer only the split is operating, keeping the roomair below 24 degree C and the rel humid. at around 50%. I don't fan outside air in and only a very little amount of air out (to keep tankair from entering my livingroom).
In the winter, the split is not operating. The outside air is dry and I use a "Stiebel Eltron DL13" fan to move inside air out and outside in. The DL13 has a cross-flow heat exchanger, keeping most of the warmth in, while exchanging air.
Spring and autum is a pain, wet outside air which should keep me away from using the DL13 and low temperatures which makes cooling/dehumidifying with the split problematic.
In this time, I use the different units, changing setups from time to time.
The additinal fan, thats normally running on low volume is speed up during this period to produce underpressure in the tankroom and suck dry, warm air from the livingroom inside the tankroom. Well, in this time the rel. humid. is about 65%, compared to 50% in summer and winter.
Without all this equpment, I would be able to keep dartfrogs or something in the room; feels like a tropical rainforest around the afternoon-rain.
As dry air takes more water than wet, I think evaporation increases if using something that removes water from the air. Unfortunately I haven't measured it. I take the water from automatically refilling 1500 l storage in the cellar.
NanoCube-boy,
most of the coral (captive bred) came with a small stone, the frags without were glued to one. The smaller frags where stuck between the LR and the larger ones fastened with cableties. Coral touching LR or glass fastened themselves over the time, overgrowing it.
Most of the cableties are overgrown in the meantime.
jnarowe,
thank you, I was really suprised comparing the pic on the first page of this thread with the new one. Looking at the different coral and how much the grew in that few months.
