Newbie safe-t-sorb questions

Should I "charge" it with fertilizers before using.
If yes, what should I use?
What does it do to my water that I will/should replenish?
What else do people mix (substrate wise) with STS?
I was going to use jobes plant and fern fertilizer sticks and place them under my substrate... Good bad idea...

Hi Amstar,

I have read both the Pros and Cons of pre-charging the high CEC substrates with nutrients. I personally don’t do it because I like to know how much N, P, K, and micronutrients I am adding to my tanks. Also, since I typically see a spike in ammonia, nitrites, and nitrates in a new tank anyway I don’t feel the need to augment that condition.

I think you are going to like the Safe-T-Sorb, other than the initial cleaning it has a nice mix grain sizes , colors, and hues.

Does safe t sorb ever become completely clean by rinsing it? Or do you just deal with the left over and let your filter clean the water?

just fair warning that you will have water haze a day or two after filling the tank with this substrate. This naturally happens with all clay based materials and its normal. There after... enjoy because its a pretty awesome substrate to work with in a planted aquarium. The consistency is light but unlike sand, it will make for easy anchoring for plants. I use this in my cray tank and have not had any molt issues. Currently in the process of building out a new shrimp tank to test to see if this will also benefit dwarf shrimp in the same regard.

Precharging will bring benefits but it is optional. There is better bang for the buck substrate on the market today...

I find myself rinsing the substrate in a bucket no less than 3 cycles just to eliminate the finer debris and particles which may have landed in the substrate when bagging. Just rinse until you are content with what you see in the bucket...
