Best Fertiliser To Buy For My Fish Tank

Hi all

I need the buy some new fertiliser for my tank. I've had some ferts for quite a while and the label disintegrated off the bottle and so I cannot remember what it was.

Tank and inhabitants details in signature.
Tank has 2 x T5 bulbs that are about 6 months old with reflectors on both.
No CO2 - I do have a DIY kit I could use but I don't use it properly (don't regularly refill it and so it's not consistent for the tank) so I don't want to rely on this.
I have added the ferts I have (previously recommended on a forum) every 1-2 weeks (sometimes longer if I'm honest)

I have added a Tiger Lotus plant today but the rest are detailed in my signature. My LFS stock EasyLife and I wasn't sure if this was a good buy (they're well respected in the region winning LFS awards from PFK for the past 4 years). I could ask them given they know the water quality down here but thought I would make some enquiries.

Many thanks!!
