Reverse osmosis?

Is reverse osmosis or RO really worth it to grow your plants like erios, rotalas and other medium to hard plants? I have been thinking if I should purchase one to see how it would do for my plants. I am able to grow plants but my friend tells me most aquatic plants really love soft/acidic water! Please tell me if you are using RO or not. I do not need you to ask me for my water parameters and dosing regimen. Just if you are using RO or not. Thanks

Haha, fair enough! Well if your source water is softish then no. If your source water is liquid rock then it may help with certain plants yes

92% of all statistics are made up on the spot.

I have a state of the art water softener system (per my spouses request when we built the home as he works for 3M).... it took some adjusting for the tanks. However....I use 50% RO in one of my tanks which has some decorah shale (helps control the pH). All in however... it is time consuming, expensive and slow (depending on your system and tank size).

It depends on what you are doing, and what your water is like..... chasing pH etc is a nightmare. IMO you work with what you have, and find the best possible solution. So I guess I dont think it is necessary in most circumstances.

Giving back creates a virtuous cycle that makes everyone more successful (as long as they cycle!)

I like your response!

Since you use RO what kind of response did you get when doing this process? Do you use RO just cuz you have it? Or are your growing soft water plants like erios? Have tried doing one tank with RO and the other out of tap? Is your tap water not that great for drinking and planted tanks?

I have small tanks and figured I mind as well try and see if there is a difference or not.

Thanks

Using RODI and purchased just for my tanks.
Tap water is municipal water and fine but KH is always between 2-3

Growing is not that difficult.

Using RODI. It's nice knowing exactly what goes into your water

Water out of the tap is awesome... then it goes through a filter and water softener.... still awesome. But for drinking we tend to use the RO as im very sensitive to 'flavors' (Im a chef).



Out of the tap (with my water softener) pH 7.6, GH/KH 3ish

One of my tanks is 50/50 RO/Tap (that has a water softener). I use the RO to lower the pH a bit

The others are just straight tap (with the water softener). It takes a lot to remineralize and fill the tank. I dont have any plants that NEED soft water. I did see pH spikes/lows and that prompted me to use coral in my filter to increase the kh/gh. It worked well.. I see less algae growth, and less pH spikes/lows.

Ah ic. Well I just purchased one since my TDS out of tap is 250! Plus I am frowning plants that need soft water. So I just invested in an RODI unit. Waiting on my test kits to test GH & KH. So hopefully I have better growth. Thanks for the response

Is that an issue? Mines 450ppm (roughly) and grows plants just fine...

I also use RO for a different tank with good success as well...

EDIT: Come to think of it... my remineralized and dosed 100% RO water is at 250ppm TDS so....

Not using RO.

TDS out of the tap is 23. Which is pretty much RO water. To get 0tds, you need the DI resin stage too. And did a Silver nitrate test for chlorine, and it barley had a reaction. So very low amounts, this might change varying on seasons though, so I use Seachem Safe anyways.

hmm, not sure. Im just gonna do some RODI for my tanks with seachem equilibrium added to see if I can get better results. I want to grow some erios! Thanks for the replies.

I like Seachem, but there liquid stuff is hit or miss.... Skip the Equilibrium and use:

KHCO3 for kH
CaSO4 for Calcium
MgSO4 for Magnesium

Way cheaper than Equilibrium and more control and no excess potassium

To the OP, not sure if this would fit your needs but, this thread may be useful. Personally I use tap water that has the KH adjusted to 3dKH.
