Lifegard Aquatics Self-Priming Pumps did you order the Saltwater Shaft Seal with it? I know that you using fresh water to test for leaks now.
FINALLY!!! There is some water in the tank!! lol Its looking good!!
Right bleedfire, for me it was a clear choice.......clean the fish room or watch the fireworks.......fish room , fireworks.It is Canada Day, Fireworks for everyone.
WOW!!!! I just read 117 pages and all I can say is INCREDIBLE!!!:eek2:
It isn't likely that you would have two pumps of different HP (1/2 & 3/4) that are both faulty (or NFG as we say in the business).
What happens when you plug the pump in dry? Does the shaft spin? If it spins, it should work under a load. It sounds like you checked to make sure the pumps are wired for 120V. Do all the other pumps work? You should check them all incase you need to order more stuff from south of the border.
There are two types of pumps available, pressure and volume. Your pumps appear to be volume pumps, however I don't believe you have posted a photo of the return pump. Volume pumps are designed for pools, spas and ponds and have limited head pressure (ability to push the water high or through small diameter pipe). The pipe diameter should be a minimum of 1.5" or split into a minimum of three 1" lines.
Pressure pumps can push water much higher and work against considerably greater friction caused by smaller diameter pipes and the numerous fittings (elbows, tees, valves etc.) it takes to get the water where you need it. Rather than increase the HP of your pumps, you may want to consider increasing the pressure rating. Pressure pumps are frequently used for industrial applications so they are chemical rated for corrosives like salt water. Your volume pumps have a direct drive shaft connected to the impeller. This is an area where the bearings and shaft can corrode. There are special silicone carbide seals available that will last up to ten years, but the standard issue seals only last two or three years in marine applications. This means leaks and possibly bearing damage and cavitation (sucking air).
Chemical pumps are magnetically coupled with the shaft and any other metallic parts isolated from the wet end of the pump (inside the volute where the impeller is housed). Magnet coupled pumps last at least 20 years in marine applications with little or no maintenance. They are also more quiet than direct drive pumps as a general rule.
The newest trend in aquarium pumps is modified powerheads such as Laguna Maxflow (not to be confused with Flomax urinary tract medication), Red Dragon, ATB Flow Star (still not Flomax), and the yet to be released Vertex Stratus (not to be confused with the Dodge Stratus) brushless DC pump. They are energy efficient, saltwater resistant, quiet, low vibration, high pressure, and in the case of the DC models, variable speed. The basic difference with these pumps compared to direct drive and magnet coupled pumps is there is no metallic shaft at all. The impeller is attached to a cylindrical magnet that fits right into the pump motor body. There is a modest ceramic shaft that holds the impeller and magnet together but it's more for balance and alinement than drive.
nineball / mr. wilson and others.. Just wanted to say I have been lurking since the beginning and I want to say.. "Awesome effort and planning" Keep up the great work and updated reefing information!

Peter,
I have been following your build and will continue to in the future. Its an amazing project and I feel many people can/will learn a lot from it when its all said and done. Great job so far!
Peter,
In response to your "thank you" - you are obviously a gentleman and a scholar besides being succesful.
Thank you from me to you for sharing this project with us - we have all learn't an incredible amount about how to do things properly - you have ispired some of the best brains in this community (Mr Wilson and others) to adopt this project as their all for our mutual enjoyment.
Well done!!! I can't wait to see this through to completion...
Congratulations on passing the 1st milestone. I have followed this from the begining and think you are doing a superb job on a project that is at a level most will never appreciate. Your comment on doing things "on the fly" does hold true for many/most smaller systems, however, I think you are selling yourself short by thinking that this project was done this way. It is unique and uncharted water, if you will, which must have issues to tweak before perfection can be had. Keep up the great work. I am sure there are many of us anxiously awaiting the arrival of the new pumps.
I check this thread about three times per hour. Awesome thread.
Mr. Wilson,
I am assuming with the pump specs you listed, you meant gallons per watt instead![]()
By the way, glad to hear you enjoyed ShoTank. It's my favorite store in Chicagoland and I have pretty much hit them all. Matt is a great guy and very knowledgeable and helpful. Makes it even better that he is closer than the rest, about 20 minutes![]()
Again, thank you Mr. Wilson for your clear explanation. You have a great knack for translation in my opinion. How difficult is it to get those brands you have referenced like the Red Dragon etc...???
Peter
Peter,
I have just gone through your thread, and I would like to congratulate you on your well-thought-out process of picking the community's collective brains, to establish the "œbest practices" for your tank. Aside from your own personal desires, drive and capability, the "œbuy-in" from the community is a big differentiator, making your build a truly collective effort.
In doing so, you are creating a valuable roadmap (complete with the thought processes, definition of objectives, the identification of alternatives and their trade-off's, etc), which will be very useful not just for yourself, but for all future new hobbyists who desire to spend more time on the conceptualization, architecture, design, and implementation planning of their large/complex systems. Truly, your software industry pedigree shows.
Like you, I spent my entire career in the software industry. I started as a programmer in 1977, spent the next 28 years with 60-80 hour typical workweeks, and called it quits at age 49 to be able to spend more time doing the things I really wanted to do. Luckily, I somehow always found the time to maintain a marine tank, starting as a high-school kid way back in 1970. I lived through the rapid successive technology-driven changes in the hobby (I remember keeping Plerogyra corals in the early 1980's, using nothing but under-gravel filters, with 20w T12 NO lighting). On hindsight, I feel very lucky that I lived though (and actually experienced) all that flux in the hobby.
I come from the Philippines, which results in a very different mindset for the hobby, as compared to the typical Reef Central member. I am lucky to be geographically right in the middle of the Coral Triangle (which means I can actually collect my own livestock, although that in itself creates many issues and presents unique challenges that the typical Western aquarist does not have to worry about). At the same time, the realities of being in a third-world economy (and spending within the limits of a third-world income level) also means that there are many compromises in terms of equipment choice, best practices, and operating costs.
I currently have two reef systems of a little over 1200 gallons combined total volume, just a little less than your volume. Going though your build paints a picture of what I wish I would be doing, if I had to do it all over again without financial constraints. I find it amazing that while we both have very similar desires and objectives for the hobby, our grossly different geographical and economic context results in very different design philosophies.
With the process and the time you have invested in systems planning, I am certain you will have a spectacular world-class tank very soon. Thank you very much for allowing myself and all other readers of this thread to share in your journey.![]()
Cheers,
Phil
BTW should you ever need anything for your tank from my neck of the woods, or should you ever visit the Philippines, just let me know. And I hope I get to see your tank next time I am in the Toronto area.
