looking at getting an RO/DI unit put in but not sure how big of a unit i should go with any suggestions? i do a 5.5 gal.(10%) water change every week if that helps any, looked at the unit on this site that puts out 10gpd will that be sufficient?

a 10 gpd unit would take 12 hours to get 5 gal. I wouldnt get anything less than a 50 gpd unit...it takes 2.5 hours to get 5 gal. check out ----, there are some good units at great prices on there.

angel,
A 10 gpd RO/DI unit is fine for smaller tanks as long as you prepare in advance.
If you plan to have a reservoir, say a 20 or 30 gallon container of RO/DI freshwater to use for upcoming water changes and top offs - then you're good to go.
The downside - if you need to produce a larger quantity fast - you can't.
If you plan in advance, and run it several days prior to needing it - you'll be fine.
I run a 65 gpd RO/DI unit - because sometimes I don't plan ahead so well.

Go with the most gpd you can afford. I bought a 100gpd up from a 20gpd, and what a difference! I can make top off water in under an hour. Also, making "water-change" water only takes a couple of hours, vs a day with the 20gpd.
I bought a aquaFX barracuda (4 stage, RO/DI) for around $200. Well worth the investment.
