I find it better in concentrated uses. I've used it in a 33gl bowfront and it didnt do much, but when I used it in my 2.5gl it made my plants go boom. I do not think it is worth the price (or the price I paid for my tub), but if you are going to do a bunch of nano's, I think it works fine if not good.
You may want to wait for some time if price is a concern.
I have my own line of base fert to play havoc into the local market.
Brownish concentrate granules.
Must mix it well with a layer of gravel/sand as the most bottom part, then cap it off with your regular gravel.
It is good that you are near, easier to ship and try.
Anyway, have used both sera and JBL lines.
JBL aquabasis or JBL florapol
I say JBL still is better, the price difference is worth the result (dont compare to denerle base fert as it is of different class).
yes i have heard that you're producing the first batch of base fertilizer in Jakarta and still on the trial period. for your information i'm using your liquid ferts and it works great. i'm hoping the next batch soon...
around $14 here 5 kg package. i hate the reading inside saying that the base ferts usually last for 3 weeks. my HC carpet won't be full just in 3 weeks, then i have to replace the base ferts? come on...
