have i got the right ferts?

hi, im new to using ferts and am about to set up my first hightech tank and i have lots of questions.

im getting nitrogen, iron, phosphorus and potassium all from the seachem flourish range. are all theses necessary and do i also need to get the regular seachem flourish?

also how long will the 500ml of each last for dosing 60x30x36cm tank and should i get the 2L bottles instead?

when i first started i started using the seachem line of ferts. However after doing the math i found out they are quite expensive to dose with (you are pretty much buying water). I recommend you do a little research and look into dosing with dry ferts. You can even make your own stock solutions if you don't want to dose with dry ferts (ie using the nutrient calculators that are available).

But to answer your question with that small of a tank i think those 500ml will last about 6-12 months depending on certain things (co2/lighting/plants/amount of plants/how much what is changed out every week).

You will need all of those and more. You will need something to dose for Ca and Mg. I recommend Gypsum for Ca and Epsom salt for Mg. Gypsum you can buy from Home depot for $9/50lb bag(will last you and your grandkids) and epsom salt from your grocery store.

If you do get the seachem line the flourish trace will run out the quickest and the iron will last the longest. Potassium also goes pretty quick. I have never used the nitrogen and phosphorus.

Hope this helps you out.

There is people all over the forum that sell dry ferts. For about thirty bucks you could have enough ferts to last you a year! Check out the swap and shop.
