Say, I know this is an older video, but do you also use an alkaline buffer to raise kh? I want a little bit of kh because my tank has close to zero. I’m also getting pressurized co2 soon and my substrate buffers the ph down below 7 and I’m afraid that with the ro water I’m putting in and the co2 being introduced that it’s just going to make my ph go down dangerously low.

Will the equilibrium bring up the pH in the water or do you have to add something to bring it to a desired pH

I am unclear how to use the calculator on the Seachem web page. Not sure what my Current GH meq/L is or how to measure, got any ideas or suggestions please?

do all ro water filter system be puted in a sink directly with an adapter? I dont want to fiddle with the pipes at home and im not allowed to do so lol

hello what kind of R O water filtration system do you recommend for a 300 gl aquarium?

I've never used equilibrium, and I'm more of a fan of the liquid supplements which don't cloud or take time to settle like powders do. When I want to raise GH, I use Replenish. I add Fresh Trace for my fish - do I need anything else?

so for asking this on something so old but is equilibrium the only one that introduces what the plants need ? or will continuum and salty shrimp do it as well? the equilibrium seems like it isn't as fine a powder as salty shrimp, does anyone know if the will have an effect on inverts? I am trying to decide which product is best for me with multiple tanks and multiple species.

If I am using rodi water and want to use equilibrium what about the KH??? It says it only fixes the gh. But wouldn't you have 0 KH and a ph disaster incoming???

if you add equilibrium does it make youre water hard that it leaves calcium stains in youre tank?
ss ss
ss ss - 4 years ago
Equilibrium increases the dGH of the water by a few degrees, and if added to an already hard water aquarium (pointless of course) then it would increase the amount of carbonate deposits on the glass.

What he's doing here is taking near pure water with no hardness at all to begin with, then he's adding the hardness back to it. The benefit of that is you know how much is in there of calcium and magnesium.

My water here is 14GH and is comprised of mostly calcium, but has trace magnesium - which isn't good. You can does epsom salts (MGSO4) to get the ratio right, however, this also raises your overall GH.
10pmgotosleep - 4 years ago
Hi Jacob, one question. Whats the GH, KH of the water after adding the equilibrium?
ss ss
ss ss - 4 years ago
This is what I was thinking. He didn't talk of the KH at all which is a bit worrying.

Given a few big water changes like this over the months without checking could see the KH drop out and the PH crash.

can you add in some part of the waste water back into the RO water?
ss ss
ss ss - 4 years ago
Nope - it would clog the membrane and reduce the life of the unit 4 fold.

As an example, my tap water has a TDS of 250, the unit filters water down to below 10 TDS, so you need to consider how much TDS is being washed out the waste - A LOT!

My waste water from the unit has a TDS of over 380. Imagine running that back through the filter. It now has to give you <10TDS pure water, but has to get that from what is effectively now liquid rock.

Like he said, this water is toxic to drink, or give to pets. I'm not so convinced it can't be used on the garden, because I do and my geraniums are exploding. Probably helped by the fact I rinse my filter mediums in that water.

Do you have to control the ph if using ro water?
ss ss
ss ss - 4 years ago
I cut 70% RO/DI with 30% treated tap water. It brings my PH down from 7.8 to 7ph.

IIRC my RO on its own is around 6.0PH.

I then inject pressurised CO2 which drops it to 6.6 - 6.4ph.

If you are cutting with tap water, there shouldn't be any problems. If you are using straight RO water and reminerlising then the KH/GH would be far more important to consider than the PH.

RO is nice to have if you live in an area that doesn't have pure water store in the neighborhood. But where I live, I pay a 40.00 membership for 270 gallons at pure water store. It saves time and money

Starkiller -86 - 2 years ago
Duc Ly ro unit is cheaper in the long run,it pays for itself and only cost £20 a year to replace Di resin and membrane,so people who go out and pay for water are spending more money

Hi Jacob, Since your using Seachem Equilibrium you don't mention how you adjust for GH? Can you please do a video how to adjust for GH and KH for Co2 usage thank you. also I have question regarding S. Repens I have it covering the foreground and looks great but all of the sudden in a certain spot the leaves became transparent and melted away or died off but in some areas there is small new growth but all the other plants are fine. Great videos very informative thank you in advanced
punchmau - 5 years ago
Hello Jacob,
How about the KH? How can I obtain good levels of KH with RO water. It seems the Equilibrium Seachem item, only takes care of the GH....(?) Please advise.
ss ss
ss ss - 4 years ago
Bicarbonate of soda - it's only what commercial products have in them anyway. Obviously they won't tell you this because effectively they are just selling you water.

Mario Aguilera

Hey Jacob I have a question for you. I used to use replenish in my tank on my ro buddie but found out it was bad for plants, so I switched to equilibrium however using it clouds up my tank for days. In fact it's still cloudy :/ I dilute the solution before adding it in, and I don't even add it directly I add it to the replacement water I'm about to put on. Please help, it's really been a stressful situation ;);)

You can find cheaper units from unbranded sources.... like everything, you will always pay extra for the name.

To be fair, it does look like a very nice unit, but meh, it's not there to be looked at really, is it?

Jacob- Thanks for posting this video. The timing is perfect for me as I am deciding between RO & Tap as I re-setup my 90 gallon from a reef to freshwater. I have an existing Spectrum RODI unit and you answered the question regarding if I should reuse it. I will. One question though; Should I remove the DI resin before filling up my aquarium? Can I just place another sediment filter in that chamber. Thanks again! -Mike in oHIo

Nice video.
The problem of using RO units is the cost effectiveness.
They tend to be a very expensive way to fight algae.
Most of the water gets wasted, in marine tanks this is almost mandatory to to keep your expensive corals alive but you can keep healthy algae free plants without RO water.
Still for he who can afford it there is benefits to it.
Starkiller -86
Starkiller -86 - 2 years ago
AQUADESIGN by aquamaniac they are not expensive,the membrane only needs replacing every 6-7 months and the replacements are only £20,it costs more to keep buying tap water conditioner,if you can’t justify that then you are in the wrong hobby,
ss ss
ss ss - 4 years ago
My RO/DI unit costs me about £30 a year to maintain and replace canisters/membranes.

If someone can't justify £2 a month, then I don't think aquariums are the hobby for that person.
