Can I use tapwater treated with prime and let it sit for a day?
Also I'm confused about when I need to add the salt mixture water vs. topping off with regular water.
If there's salt in the water already, and I do a water change, then add more salt water to it - I've increased the concentration/salinity, right?
So how do I mix proper amounts to avoid just making a complete salt solution?
Sorry if these are dumb questions,
I'm brand new to SW
and have been researching for a week and everything tells me to just go buy an expensive RO
Nothing I've found has addressed the concentration question.
Basically you have to use Rodi
, there is no way around it. Now, you can either buy the system or buy it weekly or whenever it is needed from the lfs
, as you already know. I see the only thing holding you back from buying the system is the price. There is a great rodi
system on ebay, 60 dollars, works perfectly, 100gpd. Thats what you want IMO
No...never use tap even if it is really clean, distilled, treated, or whatever.
When you do a waterchange you want to take out the same amout as you put in. That will keep your salinity the same. Likewise, if you want to raise the salinity just add more and take out less.
Not sure what you mean. There is no "complete solution." just make the salinity what you want it, using a refractometer of course.
These are good questions though!
I just want to add, topoffs are very important. Whenever the water level is dipping is because rodi
is evaporation-not salt. Replace this rodi
whenever the level dips, even slightly
