iQuaticsOcean Reef Pro Coral Salt – 20KG Refill | Advanced Synthetic Formula | Fast-Dissolving, Residue-Free | Perfect Element Balance for Reef Aquariums | Enhances Coral Growth & Vibrancy

I used to but this from Amazon as it was well priced and seems to provide my tank with everything it needs.The price has raised now though, so i buy it straight from manufacturer instead.

Love it quality

What can you say more than being a happy and satisfied user after all. It’s sheer happiness and peace of mind. The pricing for this quality product is extremely good. You can’t really get with such great product either the product will be cheap made or pricing would be really high. When I opted to switch to make my own salt water rather than buying ready made ones from LFS which was costing me more in all aspects, went through all the leading brands and this product struck my sight. Tried it on trial basis with just 10 kg refill pack. I’m about to go for the 20 kg bucket on my second purchase very soon. I don’t even use RO/DI Water. Just use normal tap water with water conditioner. My marine tanks look great and fantastic than using with ready made salt water. I tried with both RO/DI water and normal tap water really didn’t find any great difference. So I recommend this product for people who want to try. No hesitation and no send thinking guys. Go get it.

Does exactly what it should do but OMG trying to get the lid off is insane! I came to the reviews and we weren’t the only people who struggled. I was nearly ready to have my husband cut the lid off, which would defeat the object of buying the bucket!Get a long sturdy flathead screwdriver. You’re going to need to wedge it in extremely hard and pry it open’

I've been using iquatics salt now for ages and it's really good salt..no need to buy any other it's same if not better than the more expensive Salt on the market at a lot better price..mixes fast too..I like the refill option too..and It was delivered faster than expected next day infact..I may use a cup or two more than others to get the salinity bang on but you get more for your money..I'm sticking with iquatics.. it's a no brainer

This salt is great it’s cheaper than a lot of other brands not the cheapest but great value for money. The issue with the lead as since been fixed it is much easier now to open the lead. Been using it from the start it dissolves very quickly it’s us cell-free free I have it on free monthly basis delivered by Amazon. I have no bad words to say about it it’s good salt they are probably better brands out there but not at this price it’s convenient it contains all the trace elements you need. I am no longer dosing my tank because those elements are there so that’s another money saving it’s a big plus.

So I've probably tried about 4 different types of salt, some mix easy, some mix well eventually. This was a trial bucket of 10kg, as I use more than I thought. Wow, in less than 5 mins it was crystal clear, on my new nano tank.Packaging not as hard to get into as others have described, but a very tight seal whichI like as it keeps moisture out, and on a big 20kg bucket that saves waste salt. Maybe an issue if you suffer from arthritis though.Anyway, I opened the bucket to find helpful information on mixing ratios, and on the outside of the bucket was a huge list of minerals included, clearly printed as seen in pics.Sadly the advertising online doesn't show these pics but I found them helpful to see exactly what was about to enter my reef tank, and hope you do too.I will say I'm happy to switch to this product over the brand 'with a clownfish on it', I have been using, with problems controlling my phosphate and nitrate, however this bucket clearly states both of those are not in there but have ramped up levels of minerals, which often get depleted by skimmers or waste water.Overall I'd give it 4.8 out of 5, only because of the tight lid for those who have poor grip, and would struggle to get into the bucket.

I am a new reefer. We don't seem to have the same variety of Salt that the USA has and after a lot of deliberation I decided to try this as there are lots of good reviews and it's a bit cheaper than the comparable 'coral' salts.I am very glad I did.I am now on my 2nd lot of salt. Following their steps, mixing up the salt mixture before putting it into the water and allowing it to mix, I consistently get the parameters they say this salt provides. PH of 8.2, no Phosphates, no Nitrates and elevated levels of calcium etc.All confirmed with Salifert Test Kits.This can (and I do) mix in freshly made cold RODI water (which iQuatics advise) then I whack a heater in it once the water is nearly totally clear to bring it up to temp.Their measurements of 650g per 20 litres is also spot on for me (Markings on bucket are a bit out hence why some seem to suggest they need more salt, it's more than likely they have more than 20litres of water).I won't be using anything else, this is quite literally perfect and touch wood it stays that way :)
