NēoPhos Phosphorus Supplement for Reef Aquariums, 500 ml

This is a really good option for low nutrient saltwater tank! It’s does have a little smell in bottle but will not change smells on your tank. Have to be very careful to follow the bottle’s instructions a dose small amounts each day until hitting your target because it performs well! Be careful to monitor your nitrates because they work hand in hand. Calculations are easy to follow - everything is in the bottle. Due to the small mount you really need to raise your levels this bottle is definitely worth your money as it will last a good amount of time.

Great product. Awesome seller, packaging was great and even included a free sample of food my fish love. Thank you

Brightwell makes amazing products, but the packaging needs improvement. I’m a frequent customer and have purchased several times on Amazon products I can’t find at my local fish store (LFS). However, I’ve noticed that delivery through Amazon often causes issues with the packaging: the container’s seal is fragile and can break with the slightest impact. In addition, the screw-on lid does not fully secure the contents, making it easy for the product to spill. Unfortunately, today I woke up to find 2 liters of NEOPHOS spilled all over my living room floor. It’s frustrating to lose such a high-quality product due to a packaging flaw. Brightwell should consider a more durable packaging design to prevent these kinds of incidents.

Had a hard time keeping any phosphate in my system. This definitely helps.

Be careful, good stuff though make sure you test.

I was having no detectable phosphates in my mixed reef tank and my alkalinity was a little high. I lost two acroporas due to the lack of Phosphates. I started using NeoPhos and the remaining 4 all healed and started showing color. I went from a pure green RR Pink Cadillac to a beautiful pink Pink Cadillac just the way it's supposed to look! I've recently added 10 more Acros and all 14 are healthy and happy with th daily doses of NeoPhos to keep my tank on track!

As a battle dinoflagellates and hair algae this product has helped me maintain my PO4 levels and keep my corals alive. I ended up using a lot more total product over time than I expected due to GHA consumption, so I am glad I purchased the larger bottle. I still have about 100 ml remaining and have removed most of the GHA and have finally seen the ability to maintain PO4 and deplete slowly compared to before. Would purchase again in a similar situation.

great

Great stuff

Great product and it's a shame it's not more readily available. Quick delivery and great price. Very impressed with this seller

If your phosphate is low, then this product is great. Easy to measure when following the instructions

Great packaging and was very impressed that the bottle was put inside an Aquarium bag and they used a metal type of staple like you would get when ordering fish or Coral online. I bought this because my phosphate zeroed out and while I was waiting for delivery I was able to get the phosphate up to a detectable level so I haven't used the product but at least it's good to have if things do go south again. The seller is great as adult with them before and never had any issues.
