Oh... now I feel sheepish... I should have figured that. 25ppm GH and 0 ppm KH makes FAR more sense than.

BWG... not so dumb a question.

Yes, this now makes even more sense.

Trying to further clarify some things for myself first though, sorry.

When you add the tap water the saltwater fish die? You don't have any freshwater fish at the moment do you?

If that's the case I would just use your tap water to set up the tank. The fish you mentioned will love it, aside from the rainbow and that needs a bigger tank than you have regardless. Stick with softwater, acid loving fish and you will only need to harden your water a little for the plants. No need to worry about changing KH or PH.
No the freshwater fish i had all died. Now i dont have any except a little betta i just got.

Seachem's Equilibrium is what Byron uses to bring his water up to 5 or 6 dGH, the KH goes up as well so this serves to harden the water and buffer the pH at the same time. I think he just adds more EQ based on how much water he is replacing at water changes.

If you have no fish right now (sucks) then set the tank up with the tap water (treated) and plants and add EQ based on the directions to bring the water where you will want it. This will let you figure out what you need and stabilize the water at the same time... then select all new fish based on the new water parameters.

This gives you a very open book on what you can stock for fish as you can peg the hardness almost wherever you want it. The pH is best to just let settle wherever it does as trying to tinker with it chemically separately is not a great idea.

Equilibrium will only raise GH, not KH.

Right, their alkaline buffer is needed as well if both need to go up.

Also, I'm with Geo. It seems to me that unless you add a large sump, a refugium isn't going to do much. I've seen some (expensive too) small commercial hang on back refugium's and frankly see little benefit and wonder what they're thinking.
I just think there are better ways to [better] control water purity, including algae.

I'm also confused about your tap water and your use of RO water. Without adding minerals, RO water is too pure for aquarium use (fish need to absorb minerals and trace elements through a form of osmosis) ...although if your tap water is hard, you might mix the two and adjust slightly for pH as/if necessary. (I do that with reclaimed water from my basement dehumidifier.)

How acidic is your water and is that the only reason you don't use it?

You might find value in the following article:

Bro, I have a 1 gallon Marina hang on refugium, and I turned it into a bio filter. I got some leds and put them on the lid and algae grows quite profusely in it. I filled it with about an inch of sand and have about 12 ghost shrimp, 25 clams, a colony of ramshorns and a bamboo shrimp. I have 5 moss balls and some java moss floating in front of the discharge so the baby shrimp have something to cling to before getting cycled into my tank. I filled the intake tube with teeth(yes, teeth) for beneficial bacteria to colonize and it really works well. In fact, the teeth work better than bio rings I have used. So suck it, Mr. Hang On Refugiums Are Useless.

So you're saying that having a 1 gallon refugium is what allows you to have the 20 gallon in your profile so vastly overstocked?

O.O you have all that in a 1 gallon?? You realize Bamboo shrimp can get up to 5" ... right??

I don't dispute advanced bio-filtration. However, this typically does not include crustaceans and plants/algae.
(ref: bio-sand filters used in the 3rd world where foul, polluted water is poured in and crystal clear drinking water comes out).
I have a bio-filter consisting of an Aquaclear 70 HOB, using an AC20 impeller for reduced flow that has a thin coarse pad, then filled completely with a packed mixture of Seachem Matrix and De*Nitrate.
What I dispute is the effectiveness and cost (some in the $ hundreds) of many of these small HOB refugiums.

On the other hand, the one gallon marina/finnex refugium/breeder HOB may have practical application as a bio-filter and the $20~ price is right.
