Using Ro/Di water ?

[jeff williams]

Ok reefs I need some education, when using Ro/Di water it strips all the alkalinity and minerals out of the water, so for a reef tank you guys have to add alkalinity and such for the corals. However for a fowlr tank is it necessary to add these minerals back? Now it seems to me that the fish would also need these minerals and alkalinity would also be required to maintain PH. If this is the case how would I go about this what minerals are required?

For either corals and/or FOWLR you add salt to RO/DO and mix. Supplemental ALK, Cal, and Mag is added at what ever rate it is consumed by the corals, this is seen when testing for each. The salt mix will contain all that is needed unless something removes it. FOWLR doesn't need this kind of supplements.

+1
Top off water dose not need anything added to it.
When you do water change you add salt to the water which replenishes just what you want.

Ok all the traces elements and ect are in the salt. Reefs just consume all and mag at a faster rate so reefs require supplementation correct?

All Aquarium salts will contain everything needed. Corals consume ALK, Cal, and Mag that's why they are added, without replacing what the corals use up they will either stop growing or possibly die. So yes, you are correct.

Start a new thread about your fish lost. Post your water peramiters c

I did start a thread about the disease that my fish out it was Titled ick or velvet and I ended up losing the fish after doing a tank transfer method and on the final transfer everything went smooth and my fish dies a few hrs latter. water parameters were correct and equal between tanks ammonia zero nitrate zero nitrates zero and the only difference was ph the tank transferred from was 7.8 and tank transferred into 8.4. I believed the ph difference caused osmoti shock however the experts on R2R say no.

You may not find magnesium supplementation necessary, depending on the mix and how you otherwise supplement calcium and alkalinity (and how much). Some have so much that in many tanks it will never drop below NSW levels.
