Huh?
That's crazy. Mine cost $499 USD at a LFS less than 100 miles south of the Border.. (New hampshire)
That's terrible. Maybe you should take a long drive south![]()
Don't let common practice get you away the power of creativity and get you away from a smaller central sump. I run 3 tanks + cryptic tank, use to be 7 off of a 40g, with a total of 400+g of water volume.
There are many things you can do to reduce run off. All of the usual things that people suggest, but one thing I used that did just great is your PVC certainly can be part of your holding system during a power outage. In my case, there was a pretty reasonable amount of space in the PVC, and by creating natural 'wells' in the PVC, you can use it to hold water too. with 400g+ of tank I only had a 15g increase in water volume in my 40g sump. One of my tanks is a macro tank, i.e. refuge..so I wouldn't try to use a 40g as a fuge for all that water...but in terms of holding tanks....a little creativity will go along ways.
In additional thing I used, and still use is a remote water hold vessel that is part of my ATO. It is excellent for a number of reasons, and it increases the holding volume during power outages.
The easy way to plumb this system is to use two separate return pumps sitting in the same sump... Just a thought. Would allow you to split the tanks in an emergency, would give you plenty of flow, and isn't that expensive.
So like a big rain barrel or something?
Sounds like you have a sump, then another sump (the macro tank). Actually if the remote hold vessel can hold water in case of emerg, maybe that's like 3 sumps![]()
A sump is essentiall a place to hold your equipment..or in your case (and mine) the place to merge water columns and hold your equipment.
A fuge is a different beast, although many people put small ones in their sumps, I wouldn't get too hung up on it.
My fuge is just that, a fuge...I just have it on a 55g and keep it clean like any other tank..it is actually my favorite tank on the system. Much less work and quite beautiful IMO. I will admit, I too have a small fuge in my sump though, although I am likely to remove it soon.
As far as the remote holding, not it is actually just a 5g garbage can. It gives me another 3g or so of holding during a power outage. When I had all of my tanks previously I needed the extra 3g or so to keep from overlfowing, and it wound up staying after I no longer needed it because I liked the way it effected the ATO.
The main point is, if constructed properly, your PVC can hold ALOT of water. For example. I had roughly 30 feet between overflow and return PVC running between all my tanks. I setup the PVC to be capable of 'holding' most of the water..that added another 25g of water to my holding volume during a power outage.
