Thanks to those of you who responded to my plea for help/advise. I lowered
the water by 50% when I noticed the brace was loose and the front and back
panes straightened. I had cut/scraped off all the old silicone before doing
that incase the gap between the brace and the back glass closed as the
pressure eased. Later today I will re silicone it - didn't get to do it
with all the Christmas going ons. I was actually thinking of removing the
silicone holding the other end as well and redoing both ends. What do you
think, worth the effort?
While I had that thought in mind, another thought that came to mind was
removing the brace! One of the problems that I have lighting this tank was
the center brace. Being in the center, I was limited to 2 or 4
lights. The tank is a 180 gal and I currently have 2x150 watts 5200K MHD
lamps over it. I wondered if the lighting level would be too low 1.6:1
ratio, but the MHDs seem to have very good penetration into the water and
there are tiny bubbles everywhere. As the tank is not established yet, I
guess I won't know if the quality of light that the MHDs put out is better
and therefore sufficient or if I have to increase the lighting level.
I think that 4x150 watts might be too much, so by not putting the brace
back in the center I will be able to put one more light there. Maybe I
should use a temporary brace in the form of a clamp. This way If I need to
add another lamp, I will then put in 2 braces to divide the surface into 3.
What do you all think?
