Saltwater basics - RO water? really? |
|

My son has scored a Craigslist catch. |
|
A 90 gallon tank and stand for $50. Tank is about 6 years old |
|
and was built using black silicone. |
|
We understand the mixing of saltwater, and the 'live sand', but |
|
RO water feels like an overkill. Perhaps if we were keeping |
|
corals and other live sensitive marine invertebrates I would be |
|
more understanding. When I was a young boy, our favorite |
|
Chinese restaurant had a saltwater tank on display, surely they |
|
weren't using RO water in the early '60 now were they? |
|
DI water should be plenty pure enough for a saltwater fish only |
|
tank, right? I mean, everywhere we look (locally) and read |
|
online, advice is to use RO water. |
|
Would love to hear your thoughts, and perhaps suggestions on |
|
what makes a good RO unit. |

|
if a FOWLR system, you really dont need an RO unit, but it may |
|
be optimal if your water is not the greatest out of the tap. |
|
Like you said, for corals it is a must. IMO, if you have the |
|
money , get it. The phosphates and nitrates that it will remove |
|
can help drastically with the growth of nuisance algaes. Also, |
|
protein skimmers dont like some water conditioners. For RO units |
|
being had under $200, it would be wise to use one. Especialy |
|
since it would really only be used for top offs and monthly |
|
water changes. |

I had a salt water tank back in the 80's before RO units were |
|
big. I had well water and mixed it with Instant Ocean salt mix |
|
and my tank was fine, anemonies, clown fish and damsels. I only |
|
used hang on the back filters also. Just got tired of the mess, |
|
so I used the left over salt mix in my mbuna tank |

Thanks guys for the input. |
|
Definitely going the FOWLR route, with an Emperor 400 (less the |
|
bio wheels) and perhaps a circulating pump to give a bit more |
|
water flow. |
|
I'll have to pickup a TDS meter to be sure, however what would |
|
you suggest to be the max (out of the tap) TDS before going RO? |
|
I know at just less than $1/gallon DI water from Walmart it |
|
would be a bit costly to go entirely DI water. My thoughts were |
|
perhaps 1/2 and 1/2 assuming my tap TDS is in a acceptable |
|
range. |
|
Again, thanks for your help. |
