Natural Seawater Supplier

Wow what an experience! professionalism, friendliness and always happy to advise. I've currently dealt with Christina and Tony.

Christina - very helpful, organized the delivery and always seems to be on the end of emails (5am at one point I think?!)

Tony - Has called me after I had an issue with my buckets storing the sea water has gone out of his way giving me advise on my cycle which seems to be taking ages.

The delivery guy was helpful and filled each 120L buckets up in no time.

Thank you all.

I have been getting my tank water from NSWS for over a year now and all I can say is WOW...

I recieve 100l a month

Naturally, I was sceptical at first, thinking it was too good to be true... but I have to say, this water is perfect. Peramitors are always bang on, Christina is the email queen... sometimes even replying in the middle of the night.

Price is very competitive, sometimes I wonder how they do it 🤣

Delivery driver is always really friendly and like clockwork.... never have I been so impressed by a company's professionalism, quality, timing and consistency .... I for sure will be using NSWS for many years to come.

Could not recommend this company more

I ordered my initial fill of 400lt from this company. Christina was the young lady that helped me through the process. She is very knowledgeable, very kind and polite. She responded to all my emails very quickly to my surprise. The water was delivered on time and filled my tank within minutes. Being new to saltwater aquariums i thought this would be the best option. It has been seven days now and my tank is fully cycled. Amazing. I have set up a direct debit to receive 100lt every month for my water changes. Big thank to you Christina. You have made this so easy and enjoyable for me.

These guys a really on point. Needed 1000 litres, heated and delivered to central london for one of our clients. Sorted and delivered within a day of enquiry. no delays, no hassle and a superb product. Super friendly and efficient...whats not to love. I can only highly recommend these guys. They wont let you down. Big thank you from Aquatic Design Centre. Will certainly be using these guys again.

Been dealing with this company for quiet some time now and i have to say its made the hobby so worth it in the sense the level of professionalism and and knowledge is second to none! Tony has been absolutely AMAZING along my bumpy journey and had leaded me onto the right path with my new set up , the delivery driver was A******* as well and hope to continue dealing with this amazing company i am truly Grateful

Just wanted to thank you guys again and also give special thanks to the delivery driver. Was very pleasant and patient and an all round sound guy, especially for 5 in the morning! So thanks again! Look forward to my next delivery :)

Can’t fault the company as since day 1, customer services have been spot on with all my queries and quick response.
Over the period, I’ve run into issues with my tanks where, for me, making RO water and mixing with salt and heat just would take too long and with the amount required, takes almost a day of the weekend.

NSW came to the rescue since I know use to drop off 50 litres on a monthly bases to assist my downgraded 4 ft tank. I’m glad to say my ICP testing has come back with better results compared to me making my own salt water.

If making own salt water is too much or a burden, consider having filtered NSW drop off to you instead.

I'm naturally sceptical but Christina and the crowd at NSW put my mind at rest. After delivering 450L of water to a first floor tank with complete confidence, I receive 100L of water a month for maintenance. The cost is lower than making my own up and a whole lot less hassle too! I still make the odd 50L up with rodi/salt just to boost some nutrients but I can't fault the service at all. So very happy.
