The new large systems been running since December 2019 and the Red Sea S650 since June 2016
The systems are completely independent at the moment, although they both get fresh saltwater from the same system, and I think it’s now time to link the 2 together
This will effectively make the entire cabinet and filtration under the S650 redundant, and all filtration will be carried out using the equipment in the sump of the 2000 litre system which is more than capable of handing the extra water volume
This will make a huge difference to running costs, maintenance, testing and potential failures and also with the use of the Twin Tech Calcium Reactor, the water stability in the S650 should be better, although it’s fine anyway.
Im not concerned about any issues with disease or anything like that, all fish are healthy and all that will happen is the S650 will benefit from all the equipment in the large system, including powerful UV-C, skimmer, X Filter…….. When I think of the maintenance it will save for the sake of drilling a few holes…..
Ive got to check the sump can handle the extra water in the event of power failure, I’m pretty sure it can, and I can lower the water level a little anyway, and also use a good quality non return valve on the return. I’ll also drill an anti siphon hole in the top of the main return nozzle in the tank, and that will reduce the amount if water that siphons back.
I was going to buy an additional Abyzz A200, but I’ve got the original Red Sea Sicca pump and also a spare, so I thought that was a waste of money. The head pressure is 3.8m and 7000 lph. The pipe run will be adding around 5 metres so I’ll test the pump before connecting back up to the S650 to make sure its got enough power, it should have. If it doesn’t it will be another A200 and I also have a spare one of those.
The concept is pretty straight forward and basically means attaching longer pipes to back of the tank, going through an outside wall and then back into the sump of the 2000 litre system
You can see in the picture below, from left to right, the 32mm emergency overflow, the main 40mm overflow which will be refitted with a gate valve, and then the 32mm return hose. You can also see top middle, that stupid Red Sea valve which is already obsolete in this system.
ill make new connections with unions, and keep the original pipe work available in case we need to correct anything during testing.
The other option I’m considering, and awaiting a price for, is a brand new 2 metre long tank, same specs as the large system but slightly shorter, to completely replace the S650.
I don’t think I’m going to do this, because we’ve been together for over 5 years, and apart from gaining some extra space, and a much better design, the cost will be significantly higher with new lights etc., but it’s an option.
I’m just taking a few weeks to think over the plumbing parts needed, and ways of doing it, but that’s what I’m thinking.
These are the 2 systems
