Should I be using seachem flourish excel liquid ferts or tabs on my low light tank setup? Ive read articles on here saying low tech tanks may or may not need it.. Would it benefit my plants at all? Or should I not worry?

I'd definitely use Excel at least... But Fluorish may not be a good idea if you are using slow growing plants unless you have some fast growers. The slow growers won't be able to compete with algae for nutrients that I'm afraid of.

There's Seachem Fluorish and Seachem Fluorish Excel... One is an all-in-one liquid fertilizer and the other is liquid co2 substitute.

So I should get seachem fluorish excel or flourish?

I have annubias, val (I think), hair grass, ambulia, lilaeopsis and lizards tail (removing lizards tail as its not supposed to be fully submerged)

But once I get my 240L up and running I will be getting more plants.. Hence why some plants are still in pots as I will be setting up new tank with deeper substraight on weekend

I would go with Seachem flourish. Seachem flourish contains both a small amount of macro ferts and micro ferts. Macro ferts are ( Nitrogen, and phosphorus ) micro ferts are ( iron, magnesium, and boron). It's a good fertilizer to start off with. I believe Flourish Excel can melt your Jungle Val.

But if you have slow growers, you need to carefully dose or there will be extra nutrients that algae would take advantage of. I recommend having both fast and slow growers

Apart from elodia is there any other fast growers I can add to my low light tank

Also would I follow directions on fertiliser bottle or just half the amount?

Now I'm confused 1 saying seachem flourish the other saying excel? So go with seachem flourish so I don't melt my vals?

Just use half recommended dose or follow directions on bottle

I'd go with both. Even if the Val's melt at first, you can slowly acclimate them to Excel and they can make a recovery.

I'm having a black brush/black beard algae bloom in my current 150L I'm assuming due to high CO2 in tap water? So don't really need to add extra CO2 do I in the form of "seachem flourish excel"?

Standard "Seachem flourish" on the other hand is an all in one fertiliser yes? I'm finally understanding the difference however ive never seen just seachem flourish ive only ever seen flourish excel..

Excel can be used as an algaecide if you spot treat it with a syringe or pipette.

How long has it been planted? It's gorgeous. If you have those results with not ferts, I would not mess with it.
