A third sump for Chaeto and Mangroves - just thinking.
A third sump for Chaeto and Mangroves - just thinking.
My tank has four overflows. Currently they are set up as follows:
#1 - Sump #1
#2 - Sump #2
#3 - Skimmer
#4 - Emergency standpipe to Sump #2 return chamber
Sump #1 is a 100G Rubbermaid stock tank which provides supplemental filtration. It contains a 6-8" DSB covered by approx. 350# of live rock. There are three MJ1200 Mod powerheads rated at 1600 gph each to push water around this sump before it drains into the return chamber of sump #2.
Here is
sump #1:
This is the sump that is "flushed" every week by a 65G water change. New saltwater comes from the water management system on the left. Water is drained to the house sewer line from the pipe in bottom of the sump:
Sump #2 is a 95G Acrylic tank located under the stand. Currently I grow Chaeto in the center compartment of this sump.The overflow from sump #1 and the skimmer
both flow into the
return chamber of this sump.
Unfortunately, this sump is so tall that it is difficult to work inside it... everything requires tongs, grippers or some other extension of my non-NBA arms.
I am thinking about removing the chaeto from Sump #2 and placing it in a 70G Rubbermaid tank:

It would be located perpendicular to the existing Rubbermaid, and fed from the fourth overflow. (Closest to camera in photo below
This would be
sump #3 in the system, and would also drain into the return chamber of Sump#2.
Advantages:
1. I could light, examine and harvest chaeto more efficiently.
2. I could place my GAC and GFO reactors in this tank, where they would be readily available for maintenance.
3. I could place a reactor for an ozone generator that is in the plans.
4. I could place a Mangrove "crop" in this tank to share lighting with the Chaeto.
5. Using the fourth overflow to feed this tank, I could increase the flow to my DT returns. The Reeflo Barracuda return pump is currently throttled back by a third.
6. Sump #2 will serve largely as just a reservoir to contain water which flows back when the return pump shuts down.
Disadvanatges:
1. No emergency standpipe in case of stoppages in one of the dursos
2. ?
Any comments or suggestions from readers would be welcomed...
