Extra-fortified Glass and Marine-Spec Cabinets

The G2+ series of REEFER aquariums are rimless and constructed from ultra-clear, beveled-edge glass with an increased glass thickness of up to 19mm. These strong glass tanks sit atop newly fortified cabinet stands made of plywood and with Marine-Spec, water-resistant lamination. Each cabinet stand follows the contours of the aquarium glass, with the larger REEFER G2+ models featuring an additional “floating tank” aluminum support. Adjustable leveling feet & stainless steel hinges ensure a lasting and durable stand for your dream aquarium.

Improved Water Management & Plumbing

Up top, the G2+ REEFER systems employ a large overflow box with dual side-facing return pumps for optimal water circulation and increased surface skimming. The overflow box includes a lid which hides plumbing components, as well as easily-removable weir combs for quick cleaning and improved surface skimming. Water then exits from the overflow box and travels down an enlarged and rectangular inlet to the downflow pipe, allowing for reduced turbulence & quieter operation. All G2+ models also include a high precision valve on the downflow pipe, allowing for simple regulation to further tune your flow.

Reef-Ready Sump– Now ReefMat Compatible

As with the previous generation of REEFER, the G2+ sump includes a mechanical filtration compartment complete with micron filter sock(s) and filter cup(s) to keep large pieces of debris and detritus from clogging pumps and other pieces of equipment. This chamber can be alternatively used to house a ReefMat 500 or 1200-- no modifications required! Water flows from the filtration chamber into the adjustable-height skimmer compartment, where the water will be kept at a steady level to aid in the best performance for your choice of skimmer, or any other filtration components that you choose to include. The water will then flow through the final bubble trap and into a chamber where the return pump (not included) can be placed to pump water back through the Reefer tank's return plumbing.

All REEFER aquariums include a standard 2-year warranty. Register your brand-new Red Sea system within 90 days of the original date of purchase and turn your standard 2-year warranty into 3 years at no extra cost. 1-2 year extended protection plans are also available for purchase through Red Sea's warranty registration page.

This Book Will Strengthen Your Faith and Answer Hard Questions
Format: Hardcover
This book is a must read for all Christians. You don’t have to be a student of theology to appreciate the lessons inside. It’s actually strengthened my faith and answered many questions when it comes to how a Christian should apply the Scriptures to living an ethical life. It is a large textbook but it reads very well and if you want to truly dive deeper to live a more Christ like life I would highly encourage you to read it.

Very Extensive Overview of Major Ethical Issues
Format: Hardcover
Anyone familiar with Wayne Grudem’s Systematic Theology knows how extensive his work tends to be. At 1,328 pages, Christian Ethics: An Introduction to Biblical Moral Reasoning follows that same comprehensive approach, offering a systematic guide to Christian moral reasoning. Grudem’s goal is to help Christians live lives pleasing to God by obeying Scripture and making wise moral choices. His ethical framework is rooted in God’s character and the authority of Scripture, with careful attention to the relationship between Old and New Testament ethics. While many ethical themes are drawn from the Ten Commandments, Grudem argues that the moral law remains applicable today, while the ceremonial and civic laws have passed away with the coming of Christ. Readers will notice that his chapter on civil government is adapted from his earlier work, Politics—According to the Bible: A Comprehensive Resource for Understanding Modern Political Issues in Light of Scripture. Grudem argues that moral right and wrong are grounded in who God is—not in human consensus. God’s attributes (holiness, love, justice, and truthfulness) define what is good. As such, Grudem holds to a form of Divine Command Theory: God’s commands flow from God’s nature. God does not command arbitrarily, because his moral will reflects his unchanging, holy, loving, and just character. God’s nature is the ultimate standard of goodness, and the Good is not external to God (contra Plato). Therefore, Grudem stands within the theological voluntarist tradition associated with Augustine, Calvin, and Reformed orthodoxy. For Grudem, ethics is ultimately about imitating God (Eph. 5:1), which stands in direct opposition to moral relativism and situation ethics. He devotes chapters to honoring God through avoiding idolatry, truthfulness in speech, and faithfulness in Sabbath observance and devotion. Grudem also addresses the moral obligation to protect life, engaging debated issues such as abortion, euthanasia, suicide, war and self-defense, racial discrimination, and substance use and health decisions. He presents arguments alongside counterarguments, seeking to ground his conclusions biblically. Regarding authority, Grudem argues that God exercises authority through parents, societal structures, civil government, and the local church. Christians are called to obey civil authorities, though civil disobedience is justified when the state commands what God forbids. Grudem defends a just war position, arguing that war can be morally justified under certain conditions and that governments are authorized by God to use force to restrain evil. In his view, failing to stop evil can itself become immoral. As a result, he rejects Christian pacifism as an absolute position. Jesus’ commands regarding non-retaliation (e.g., “turn the other cheek”) apply to individual Christians, not to the state’s responsibility to uphold justice. The book also addresses marriage and related ethical questions, including marriage and divorce, birth control, IVF and reproductive technologies, pornography, and contemporary debates surrounding homosexuality and transgenderism—all discussed within a biblical framework. Grudem affirms that divorce is permitted in limited biblical cases (sexual immorality and abandonment), though never ideal. I would add that abuse should also be considered legitimate grounds for divorce. He rejects divorce based on incompatibility, unhappiness, or a “loss of love.” Additional topics include private property, work and rest, wealth and poverty, personal stewardship, debt, business ethics, and environmental care. As in his previous writings, Grudem maintains a complementarian view of gender roles, arguing that God designed men and women for distinct but complementary roles, particularly in the home and the church. Throughout the book, Grudem emphasizes human responsibility, freedom, and moral accountability. Our choices carry real moral weight and real consequences. One of the book’s strengths is its emphasis on the heart in ethical reasoning, serving as a corrective to purely external, rule-based moral frameworks. For Grudem, genuinely Christian ethics begins internally and works outward—a point with which I agree. Drawing from Jesus’ teaching in the Sermon on the Mount (Matt. 5–7), he argues that ethics without heart transformation inevitably becomes legalism. Overall, readers will likely find Grudem’s positions conservative. While he does not dismiss natural law arguments, he clearly adopts a “Scripture-first” approach. This book is especially well suited for pastors, as congregants regularly wrestle with complex ethical questions and need biblically grounded guidance.

What one Would Come to Expect
Format: Hardcover
It is typically what you would come to expect from Wayne Grudem. Those familiar with his Systematic Theology will find the material here familiar. Of course, he is dealing with a new set of topics by applying his theological rationale to a set of ethical issues. There a wide set of issues covered here. The reasoning is typical mediocre and the theological development is fine, fair, just ok. Theologically it is a bit thin, but its a nice handy resource, and if you're inclined theologically in a similar direction, then its not a bad collection of essays on important issues that evangelicals need to think about more carefully and critically.
