Ro/di - Aquarium Advice

tawolcott · 03-05-2008, 11:24 AM

Ok, so my RO/DI arrived the other day. After all the back and forth (both decision and the **** store for water) I decided to join the cult.

One question I haven't seen asked is related to the switch over. Should that be a gradual thing. First week 4to1, next week 3to1, etc etc..

I've got a 30g FW and 75g FOWLR.

Just unsure if there needs to be an acclimation period for the different water content. Would seem to me the same rule should apply as far as acclimating the fish into the tank (in general of course, I have no intention of dripping water in and out)

Thanx in advance

Not sure I understand the question. With a new RODI system you need to flush it by wasting the first 3-5 gallons of water it makes. Then use the RODI water to replace the water that evaporates, and for mixing a pwc batch.

I'm not sure about using RODI water for FW tanks. You may want to check into that.

No, the question is should I ease the new water into the tank or just start using the ro/di water for full partial water changes

Just use RO/DI all the time now and for everything....top offs and pwc's.

No need to ease into it. Just go ahead and use it all the time.

Absolutely!! Now is the time to be doing your PWCs with your new RO/DI water! Top off with fresh RO/DI water too!! Your tank will thank you!

Let me make one comment here:

Use the RO/DI right away with the salt tank.

Do NOT use the RO/DI with the freshwater tank.

Pat can you explain, I'm not sure I see the difference for this issue between SW and FW?

Found this comment on Algone.com:

"RO water can be used for marine and reef tanks as the salt mix provides all the essential minerals and salts needed. Straight RO water is not acceptable for freshwater as it lacks essential minerals and salts. You must learn how to adjust the water chemistry if you use RO water for freshwater tanks."

Comments? Really gonna PO me if I shouldn't use for both

Yes, I have always heard exactly that, which is why I cautioned about using it in FW till you heard from others. RO strips too much form the water. Best to use tap for fw.
