How much stuff do you have and what's it worth? Might be better to sell everything and start over, you can buy used furniture and whatnot when you get down there. May cost less than $5000.

OP was based on 100 gallons, and how do you get enough LEDs, drivers and heat sink to replace 1200W of halide plus supplemental for $1200? That's more than 200 LEDs which will cost over $2000 with...

Yes I agree with the theory but that's all it really is, a theory. Solaris fixtures came out in 2007, that was 4 years ago and yet no price drop in LED fixtures yet, some cost more. So in another 3...

If temperature remains the same then the saturation level remains constant meaning a constant SG as well, should be about 1.200 at room temp.

Saturated saltwater has a density of approximately...

I don't recall a time T5HOs where much more than they are now, I remember some fixtures costing more than others but it's still that way. The difference I find is that back then fixtures and bulbs...

Doesn't seem very accurate to me, some of the electrical costs seems to be based on 24-7 usage so realistically it'll be half that at the most. Also the bulb replacement cost is awfully high on some,...

It was $80 worth of stuff and I didn't pay duty. I don't think I've ever paid duty or GST on any items shipped USPS. I even just ordered $600 worth of bathroom fixtures and paid no duty so I'm not...

Yeah the major attractions for LEDs for me is heat and control. Heat not so much because I've never had a real issue using 500W of halide on a 100 gallon tank, a small fan and open top keeps the heat...

The savings are not huge, you may save money in the long run but your payback period will be a few years or more depending on how you look at it. Typically you can use about half the power with LEDs...

You don't need to match pumps if you use a float, I posted an explanation earlier involving a slow fresh water top off and a fast saltwater top off. Using such a method will result in stable levels. ...

Filtered RO water is always better, I believe it's a requirement for reef tanks and a good option fish only. Some manage fine with tap water but many also have issues.
