OK. I Live in Florida and water goes quick. If I don't do something, the future corals' health will go quicker from the rapid changes in salinity . I want to have a 5 gallon top off that is very reliable. does anyone have a good setup or know of a site that has very detailed instructions and pictures (I need pictures; I'm completely a visual learner.).

I have a kent marine plastic float switch. I put it in my sump and ran RO line to a 10 gallon holding tank, this goes in through the bottom and a bulkhead with a jhon guest fitting.

I did not go the powered route, because I figured it was more chance for failure, and this setup only cost me $20.

that's one to consider. simplicity is always good. How is the float switch mounted to the sump. Pictures of top off setups would be greatly appreciated.

I just read something funny on that link. on the bottom it says "Note: Not recommended for level control in aquariums."

Why else would it be on that site? It sounds like a disclaimer.

I know that top offs are simple, I just want to see a bunch of ideas so I can see which is best for me.

Right now they are both drilled, but on my 50, before I swapped sumps, I used a small acrilic holding bracket I made.

I will see if I can find a pic of my sump, or never mind, that will just show the valve.

The problem is that the holding container is 50 feet from the tank, so showing a pic of the system is impossible. Sorry.

Before I heard an idea just to drip feed the water with a 5 gallon jug and two valves. While I like the simplicity. I don't like the feeling of helplessness while I'm away.

Does it really? Huh, that is marine depot's sight. What that valve is ment to be is a RO holding tank switch, to hook up to your RO system and shut it down when a container is full.

What they DON'T want people doing is hooking their RO system right to this valve in their sump, because if a wire from your return pump ever jamms it down you have one heck of a mess and lots of dead critters. (100GPD supply of freshwater)

That is why I run it to a 10G container, that will only drop my SG .01 in case of failure. The only time it has ever failed open was due to a cord jamming it down or something. I did have it fail closed once when kalk crusted it up, but I just cleaned it out.

I have used this valve for a good 2.5 years now.

I use a JBJ auto-top off. It has worked without fail for about 1.5 years. A lot of people will do DIY projects on this but you can get one of these for about $80 an know it's reliable. Just add a power head and be done with it. Good luck.

oh. well this does sound like a promising idea, with a low hazard potential. Do you think two feet above the sump would be high enough?

the expensive, yet safe way. Hmmm, I think i'll try DIY first before dishin' out that kind of money. I have to try and be cheap and efficient. Great idea if I could afford it though.

Yes, my 15's is about that far above the sump and it works great.

I use a 4 gallon holding tank for the 15 for the same reason. If something fails, and it dumps 4 gallons into a tank with a 22 gallon total volume the SG does not drop low enough to kill anything. Also the RO line doesn't pass water through it too fast, so it would take about a hour to dump in.

But if the holding tank were 20 gallons, it could kill stuff.
