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

Excelente rendimiento
Desde que uso Seachem Reef Complete, he notado un cambio muy claro en la estabilidad de mis parรกmetros y en la salud general de mis corales. El producto viene bastante concentrado, asรญ que con una dosificaciรณn pequeรฑa ya logro mantener el calcio dentro del rango ideal sin necesidad de estar aรฑadiendo grandes cantidades todos los dรญas. Lo que mรกs me ha gustado es que no solo sube el calcio, sino que tambiรฉn aporta magnesio y estroncio, lo cual ayuda mucho a evitar la precipitaciรณn y mantiene mรกs estables los niveles del tanque. En mi caso, mis blandos y LPS reaccionaron rรกpido: mejor extensiรณn de pรณlipos y crecimiento mรกs consistente. El lรญquido es transparente, sin olor extraรฑo y se mezcla rรกpido en el agua sin dejar residuos. Tambiรฉn agradezco que Seachem incluya las instrucciones con medidas claras segรบn el nivel que buscas alcanzar โideal para quienes estรกn empezando y para quienes ya llevan tiempo cuidando un acuario de arrecife. Despuรฉs de varias semanas de uso, puedo decir que es un producto confiable, econรณmico y prรกctico para mantener la quรญmica del acuario en orden. Lo seguirรฉ comprando sin duda

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.

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.

It'll work, but there are better ways to dose.
This performs as expected, but I have moved on to alternative methods of controlling Ca, alk, and Mg that I feel provide more precise control of these levels at a much more affordable price point. The bottom line is that every reef system is going to have different ionic demands depending upon the types and quantities of coral in the tank. There is no one-size-fits-all dosing regimen. Anyway, I just don't see the value in this product anymore. There are much less expensive ways to maintain your Ca and Mg levels, and trace element dosing is simply a non-issue if you are doing even infrequent water changes. If you're looking at this product, you obviously are concerned about maintaining your tank's water chemistry - good on you! Before you decide to commit to a commercial solution, I'd encourage you to look into making your own "homemade" stuff and using a dosing pump. I resisted for a long time, but now that I make my own stuff and have the automation I'd never go back to manual dosing or paying out the nose for commercial preps again.

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