Reef Builder, 600 g / 1.3 lbs

Very disappointed! Item arrived damaged, Opened, Discoloration on lid and inner opened seal.

Good product works well as do all seachem products . overpriced like all seachem products visit my page www.humblekoi.com

I guess this does what it is supposed to as my husband still uses it for his salt water tank. =P

I've been using this for a while in my salt water tank to keep the corals happy. The price of this larger bottle was less then the smaller one at my pet store. Great Deal for a necessary reef product.

Excelente

Great for keeping reef alkalinity stable. The directions give an outline of how much of the product to use, and online calculators can help you use this specific product to adjust alkalinity in your aquarium.

This is the first product I have used for dosing alkalinity and there is no need to switch I am very happy with this product and the change it has made in my tank.

Reef Builder is one of the bests ph stabilizer i've used so far. I use it once a week on my reef aquarium (and use Purple Up once a week too). Both are great.

El bote tiene una tapa de rosca y luego trae un cierre hermético se supone pero no se si es fallo de fábrica o qué pero no estaba bien pegado y no me fio mucho de si está bien el producto o no. He pesado el bote que son 600gr de producto y pesa algo más de 600gr así que no se si falta producto o si está en buenas condiciones o qué ha podido pasar.No le he dado a devolver el producto porque me van a decir que lo he abierto yo, pero después de haber comprado muchas cosas por internet estoy viendo que no te puedes fiar de todo y sin conocer la procedencia ni nada ahora no se si el producto está en buenas condiciones o no... o a saber si lo que hay dentro es lo que debería estar. He hecho una prueba y con test he visto que los valores de Kh suben al usar el producto, pero no se si puede tener algo más o si pueda afectar algo en mi acuario....En fin, a partir de ahora me pensaré mejor comprar productos en una tienda física y no aquí en Amazon.

Bought as I need it quickly,but on opening the foil seal wasn’t secure and there was some sort of contamination left in the powderAnd on the side of the container as you can see in the picture Will be sending back and won’t be buying thisAgain .When items are sealed they usually have a plastic backing on the foil which makes it hard to remove this was flimsy I don’t think seachem would use this method to secure their product think twice before buying
