Dosing Phosphate using Trisodium Phosphate - UK

[Zevulos]

Hi,
Im looking at getting some Trisodium Phosphate to help me dose my phosphates from reading 0 as my SPS have started loosing a lot of colour from what i think is too low nutrients (0 nitrate, 0 phos and my alk dropped to 5DKH :O ), ive used Rany's guide for dosing Potassium Nitrate and sodium bicarbonate to bring my alk back up to 7.5 (over a few weeks) and now its holding stable with my 8x a day dosing, ive also upped my nitrate to 5ppm and only need to dose it a couple times a week.

My problem is, im struggling to find any Trisodium Phosphate in the UK.
These are the options i have
https://www.intralabs.co.uk/trisodium-phosphate.html - listed as technical grade (industrial grade)
and
https://mistralni.co.uk/products/tsp-trisodium-phosphate-hydrate?variant=213251827 - Technical Grade

Which would be suitable for my tank ?

I’d avoid technical grade. It’s a common food additive, so it would be surprising if it’s not available.

Ive looked for a while an cant find any food grade ill keep looking

If you can’t find a higher grade, technical is likely ok. The doses are small, so impurities are not as big of an issue as with other additives.

Thanks, is there anything else that would be easily available in the UK ?
