Sup guys... I'm starting a 5 gallon tank this week. it'll be med - lightly planted for shrimp & maybe few small fish. problem is, I've got really hard water here (DFW, TX) and I've read shrimp like softer water. Think the GH is somewhere over 150 (not sure, use simple 6 in 1 test strip)...

was wondering what would be the best (easiest) option for agua?? since it's a small tank, figured buying few gallons every week wouldn't be so cost effective if it benefits my little ones'... spring water by the gallon be OK? would it have all the nutrients my plants & Inhabitants need?? any better option? thnx ahead :icon_bigg

thnx mrgreen, I'm gonna start w/ RCS for now, and get some CRS in few months. thinkin about putting few celestial pearl danio or few Cardinals in there as well... all the detail about shrimp says they like moderate hard water. just was looking for another option beside RO to mix w/ regular water maybe...

thnx Laura, but I though RO water lacks nutrients for plants and inverts?! was just lookin for other options, then tap water. I'll just stick to my hard water for now, but once I bring in CRS in few months, should I mix (e.g. 1/2 tap & 1/2 RO water) or some other type of bottled water??? thnx for ya'll response. :)

Yes, usually you either reconstitute RO water with a product or mix in a little tap water (like 90% RO water, 10% tap is usually enough).

But it's always best to top off with RO water as F22 mentioned, since evaporation leaves the TDS still in the tank.

Well, RO water isn't all created alike... theoretically, the RO filtration process removes just about EVERYTHING from water- but in practice the membranes get old and clogged, different filters have different tolerances, etc...

Trace elements (eg calcium, potassium, magnesium, manganese, etc) are needed beyond just pure water.

Seachem has a good product for reconstituting RO water - http://www.seachem.com/Products/product_pages/Equilibrium.html

Whether or not you need to add ferts to your tank depends largely on how much light you're putting over the tank. Stick with a "low light" setup and you shouldn't need ferts (I don't add ferts to my own 10gal RCS colony tank).

Reverse Osmosis is a filtration process that cleans and removes solids from hard water. You can buy RO units that fit under your sink, and soften tap water. I recommended RO water to you b/c CRS prefer soft water but you said you have very hard tap water.

well, it's a 5.5g tank (16x8x10h) w/ 27 watts (qaud) CF desk lamp. that should be med+ lighting...

& yes, not that herd bout would say over 150 (on 6in1 test strips). and planning on purchase RO water from LFS every month or so once I get started... :)

If you go for densely planted, high light and/or low bioload, you could minimize the need to do water changes.

Then you could trim the plants to remove some of the nitrate/nitrite from the 'system' instead of doing water changes.

I think that some people on this forum have tanks where they haven't done water changes in months.:drool:

thnx m8e, but wouldn't risk no water change on a small 5 gallon. it'll be decently planted (HC covering the ground, and small bunch of moss scape I had in mind)... think 20-30% WC be a must for this tank... ah, got a nano canister filter on order for this lil one, btw.
