Keep your corals happy!
Works as it should, priced competitively, so whats not to like? Great for getting your calcium up with minimal solution. I use it in conjunction with the Reef Fusion 1 & 2, but this gets the calcium and magnesium up without iron that can be utilized by algae. Also it is more concentrated than the Reef Fusion 1, so it is very useful when your calcium levels take a dip and everything else is fine. If you plan on keeping SPS, or honestly even LPS healthy, checking and maintaining ideal calcium and magnesium levels is a must. For the price, this is a great additive for new and experienced reefers alike.

Desde que uso Seachem Reef Complete, he notado un cambio muy claro en la estabilidad de mis parámetros y en la salud general de mis corales. El producto viene bastante concentrado, así que con una dosificación pequeña ya logro mantener el calcio dentro del rango ideal sin necesidad de estar añadiendo grandes cantidades todos los días. Lo que más me ha gustado es que no solo sube el calcio, sino que también aporta magnesio y estroncio, lo cual ayuda mucho a evitar la precipitación y mantiene más estables los niveles del tanque. En mi caso, mis blandos y LPS reaccionaron rápido: mejor extensión de pólipos y crecimiento más consistente. El líquido es transparente, sin olor extraño y se mezcla rápido en el agua sin dejar residuos. También agradezco que Seachem incluya las instrucciones con medidas claras según el nivel que buscas alcanzar —ideal para quienes están empezando y para quienes ya llevan tiempo cuidando un acuario de arrecife. Después de varias semanas de uso, puedo decir que es un producto confiable, económico y práctico para mantener la química del acuario en orden. Lo seguiré comprando sin duda

Wonderful supplement if you want your corals to thrive
I love this supplement. I recommend it to others. I have a 20g tank that houses a range of SPS, LPS, and softies, including Duncan Head's, Goniopora, Hammer Coral, Zoas, leathers, and more. Previously, I had larger tanks, but I haven't set them back up since a move. I have used this product for the last year or so and my tank is doing phenomenally (in conjunction with Reef Trace from the same company and Lugol's for my Xenia). There's not much more to say than that—this thing gets the job done. If you want a thriving underwater garden, it's a lot like an above-ground one: adding the right things helps. This is one of those things to add. I recommend it to others.

Amazing!
This product is amazing. I have always had a difficult time with coralline algae but once I started to use it's made a huge difference. I now have purple spots showing up everywhere even on my ornaments. Also since using this my pulsing Xenia have grown rapidly, I have new growths literally every couple days or 3 days and I have only been using this for about 2 weeks maybe 3. This stuff is amazing

Use this all the time to supplement nutrients in reef tank
Repeat buy for me. Does extremely well at maintaining the nutrient levels needed for my corals. The price is really good as well for how much you get.

Dosing for 10 gallon aquarium
My ten gallon tank was at 340 calcium clearly on the low range and I added a total of six ML and it went up to 400 calcium making for simple math in that each ML of solution will raise calcium approximately 10 points for my size tank. Note that directions indicate this is near the maximum that should be added in a 24 hour period. Hope this helps a fellow nano tank user.

Dislike the fact it replaces all elements as my aquarium is always high in calcium and magnesium.
