Questions - Need some input

For a frag system is a baffle really necessary? Other then looks in main display do bubbles harm the system or cause any issues I am not aware of?

Am slowing learning what this animal needs to be happy.... For example,

Enough flow to support itself. In good flow now, as in low flow it seems to sag as if to heavy.

I've had it for few years and quite slow growing? Not sure why?

My question, note the right edge in the pic, it continues day after day to not quite extend tentacles/polyp thingy's. What is it saying?

After some discussion with my better half, I recently started purchasing components for my next tank!

The tank will be an Oceanic 75g RR with a yet undetermined size sump/fuge underneath.

Lighting will be a DIY LED build and will consist of:

• 30 x CREE XP-E Royal Blue
• 10 x CREE XP-E Blue
• 20 x CREE XP-G Neutral White R3

The lighting will be driven by 6 Thomas Research Products Drivers - 4x 25W for the blues and 2x 38W for the whites.
Lighting will be dimmable ...

Hey guys,

I had a few questions about the proper way to resilicone an old tank. I have a new to me 75 gallon tank which made it into a few pictures on here previously (link). The silicone between the glass panels is fine. However, the silicone around the internal portion of the tank has gotten beat up and scraped into by its former owner.

After last nights horrible storm that produced a 3 minute surge followed by an outage, my Apex display is no longer working. It is lit up and the controller is working as far as I can tell. However, the display is blank. I tried power cycling it a few times trough out the day and have not had any luck. Anyone have a similar experience that has found a fix? I lost a large tree last night and had to take a day off of work to clear the road, so I am hoping that I won't have to buy a new one.
