Hello Fishlore,

So i've had my 50 ish gallon planted tank for over a year now and i'm quite happy with the results of how my plants are looking. However..
Some of the plants just aren't thriving (they still look decent/good but some are stringy and some leaves are lacking some nutrients, bottoms of the stems of some plants are missing leaves) and i have been using EasyLife Profito all the time now (15ml twice a week) and heard from many different people that it just doesn't have good macro and micro nutrients.

I've been looking at different all in one fertilizers which are available near me and heard alot of good stuff about Tropica Specialised Nutrition. It contains nitrogen and phosphor which i don't really need but it is also high in macro and micro nutrients which my plants would appreciate.

Let's say i keep on dosing my Easylife Profito (15ml twice a week, change nothing about it) and on top of that add maybe 1 pump of the Tropica Specialised Nutrition each day to my aquarium. This Tropica stuff is way more expensive and i simply can't afford to switch over to it completely yet.
Will this do any harm as they're 2 different all in one ferts? Will they work against eachother or something?
Would love to hear you guys's opinions and experience with this. Feel free to ask any questions if something's unclear as my English isn't perfect and i'm very bad at explaining things in English lol..

You can do both, but really what's missing in the Profito is nitrogen and phosphorus. Why don't you need these?
Profito has a mix of micros already, so most of what you're gaining from Specialised is the N and P.
Also check your water hardness (GH), if it's soft Ca and Mg may need to be added separately.

My GH is 8, so around medium hardness, and i've had some struggles with Hygrophila polysperma. The lower leaves would go a bit yellow ish and started having holes in the leaves, which told me i was lacking K, water movement is fine also and it's getting enough light. I removed the plant completely because it was a pain for me. I've just seen the amount of micros in Profito and the Tropica brand and noticed that the Tropica one has double the amount of K which made me want to add the Tropica in a low quantity in addition to the regular Profito dosing. If that makes any sense

I think the Tropica for sure would be an upgrade, and you may want to make it your primary fertilizer with occasional Profito
