Tap water calgary

[molotov]

I also have a question regarding RODI units. Are all RO also de-ionizing units? Do I need to buy a marine grade one or can I buy an undercounter unit and have them do the same job?

I just picked up a Hanna phosphate digital tester from Dave (concept aquatics) and tested my water. It is at 0.049 ppm. Should I be concerned? I only have LPS in the tank and would ideally like to move to SPS in the future. Tank has been up for almost a year and been running on Calgary tap water all this time. No algae issues at all except for the typical build up on the glass.

The phosphates likely did not come from the tap water. Try checking tap water for phosphates. It'll probably read zero. At least I read zero when I tested tap water for phosphates a few months ago.

Your phosphates are probably being introduced through fish food. If phosphates are a concern to you try running some gfo (granulated ferric oxide) in a reactor.

Not all RO units de-ionize. The De-Ionizing is performed by a special cartridge that is connect to the RO unit. You'll know if the RO unit does De-Ionizing if it is an RODI unit where the "DI" stands for De-Ionize :-). Although, some people do use the term RO in a general sense even if the unit does de ionizing as well. Confusing, I know. It is best to ask the vendor if the specific unit you are looking for does DI.

You don't need a marine grade one. Actually I didn't know there was even such a thing. You can use an under the counter unit.

Thank you Kien.

So the only reason to use RODI water is because of the total dissolved solvents and phosphate run off in the spring, if you get that. I was under the assumption that phosphate was a big problem with tap water but I also live in a new home with abs piping.

It's easy enough to test your tap water for phosphate. Then you'll know for sure if it'll be a problem or not :-)

Yes the other junk that is dissolved in tap water will end up in your tank. Whether or not that's actually a bad thing, I don't know :-). There are lots of people who use tap water for their reefs with success.

You're welcome

Our water is good to me, all I could ask for is a phosphate reactor.
