Question about my tank.
Well, All from my most favorite vacation activities: Diving !
So, I designed and get LFS built it for me.
- Main tank has 2 seperated divides, big big front for displaying, small rear (about 4-5" width is for overflow with all drains and returns drew builtin.) total about 170G. Sump at the bottom under stand and about 40G: Drain section with bubble reducer and prefilter, then to skimmmer section and overflow to Refug section, then to return box which water will be pumped back to main tank from there.
- ATO are DIY aswell with 10G for it and the sensors were bought online.
- Auto doser for 4 different choices (So far, I have 3 in mind (Seachem Complete, plus and calc.) the other still sitting dry, might be for some kindda "food" when go on vacation.
What else, Oh...
- Light is t5 8x54W I forgot the brand, hehe... sump with 24W T5 aswell. I can't risk by using MH, too hot for under the stand. Al light are autoset for D-D and daylight saving. For now, I only turn 1.5hr aday, and increase 30min every 2 weeks.
- 2x300W heater (theone made of Titanium, unbreakable ?!? (I wonder, never test it)
All return together to maintank are 3 out puts, I added 2 "blow" for current, but still wonder if current would be too strong?!? - Find out later. All the returns +"blowers" are connected to to auto feeder circuit to be set to slow down to minimum when feeding (still working on it, too busy for now)
My bad is I travel alots, so I realy realy need some automatic system work flawless, like ATO, Auto doser, Auto feeder and auto lighting. All seem to be ok now, just only the FEEDING are little complicated due to the water current, but I will make it work very soon.

* Hospital, that's what people call, I do have a 29G system with everything except ATO and autofeeder for what we called, Hosital tank.

That's about it, I believe. And I do really hope it wont turn me down for just trying to bring those truly nature (I've seen from Diving) into my house ! LOL
What an expensive pictures but I think it's really a well reward !!!

Have fun reefing and dont forget to help me out as this is my first ever "step" into this hobby.

Thanks guys, gals !!!
