Stupid Question

Are RO filters for sw mainly?

Or can they be used effectively for freshwater?

Thanks! I think saltwater people will know this answer quite easily whereas I do not.

yea you can use ro water on a fw tank. i do on all of mine. you just will need to add back some trace minerals

So its worth it?

 

[ilostnemo]

Especially if I want a sw tank down the road? (hopefully not too long a road)

I think I want one under $200

 

[ilostnemo]

even more so yeah, id deff get one if i had the money, and well id see if you can find results for the solids still after the ro unit. some units dont even remove half

 

[User]

ok so the more they remove the better? I need to do more research...

 

[ilostnemo]

yes. you want the water you use to have zero ppt and zero disolved solids.

I use RODI water with my 40 gal fresh. I just use 1/2 tsp of Kent RO Right in a 5 gallon batch

Used to have some stringy brown algae and within 4 PWC's saw a world of difference. Like you, I thought about it and said, what the ****. I already own this unit might as well use it for both tanks.

Lol dont own it yet but I plan on buying one. It triggers the spawning for some species as well

That's cool. It'll give you time finding one at a great deal and then tinkering with it until you get your reef.
