If in doubt go for the largest sump that you can physically fit in the cabinet. An algae refugium uses macroalgae to reduce nitrate and phosphate as it uses it as a nutrient. Place a bright light in the sump and the macroalgae will grow, lock up nutrients, and then you harvest a portion, and nutrients are removed at the same time.
Tiny critters like copepods can feed and breed in a refugium and as their numbers grow, a proportion will overflow into the pump chamber and be pumped into the main tank as natural fish food. How does an aquarium sump work? How does a sump work? How to deal with evaporation The most common concern with new sump users is that the pump in the sump keeps blowing bubbles. This is where the concept of an overflow is introduced and needs to be discussed briefly. This box has hole s where a bulkhead fitting it used and PVC or other types of tubing is used to send water down to the sump.
As long as your plumbing is large enough, whatever the gallons-per-hour rating is on the pump GPH is what the gravity feed will match head pressure needs to be calculated her as well and is provided by the pump manufacturer. In other words, the velocity of the water flowing is determined by the strength of the pump. It is always a good idea to use a check-valve on your pump to avoid a water siphon from he display and also only fill up the sump half way up or lower so there is room for water to flow down when power shuts off without overflowing the sump.
One of the things that motivated me the most to implement a sump was my dissatisfaction of looking at equipment inside the aquarium display.
I find heaters and pumps not so pretty to look at : My first 46g reef aquarium had a heater, hang on back filter, and a circulation pump in the display accompanied by electrical cords showing in the aquarium — ughhh the horror! So, once you have a sump implemented, the heater s could be moved down into the sump. The ugly part of the hang on back filter was now gone as well…combine all this with a black background in the aquarium and whatever nozzles are present are not very visible to the human eye — success!
Love it! My canister filters have always been good to me, but I began to weigh the options between a canister filter vs a sump. Would one be better for me over the other? When it comes to filtration, there can be a lot of frustration. These filters suck water up through a lift tube and into an external filter or canister where it is then forced through various filter medias to clean the dirty water.
There are multiple options as to which way the water will flow through the filter. This all depends on which one you choose to use. Once the water has been filtered through the canister, it goes back into the tank. Most canister filter models have water pumps that are built into the cover or base, but some require a separate external pump. You can purchase sump setups or build one of your own. Water is then pumped from the sump and into the aquarium and then back into the sump.
If you do it this way, the pump can run constantly. To me, this just seems like a pain. Water is returned from the sump to the main tank. This is accomplished with a circulation pump placed in the sump if the pump is submersible or plumbed in adjacent to the sump if the pump is not submersible. In most cases, water is pumped from the sump into the aquarium, and then allowed to flow back into the sump. In this way, the pump is allowed to run continuously. In some cases, however, there may not normally be water getting into the sump.
In these cases, the pump needs to be switched on and off as water collects in the sump. This is normally accomplished with a float switch, similar to the floats that turned off the water in old-style toilets, or the switches that automatically turn wells back on when stock water tanks start to get low. Since the main reason for having a sump set up with your aquarium is to keep water or aquarium waste from spilling out onto the floor, you need to make sure that your sump is large enough to do that in the case of a problem.
In general, this means that your sump needs to hold all the water that can drain out of the plumbing, filters, or anything else in the case of a power failure. That doesn't mean that the sump needs to hold all the water in the tank too, the tank should not be able to drain in the case of a power failure.
The sump just needs to hold all the water in pipes, plumbing, tubes, or other containers that allow water to flow into the sump in the first place. Usually the easiest way to do this is to set things up and get things running, then turn off the power to the tank and let water drain into the sump.
This will tell you how much water drains out of everything into the sump. While the power is still off, fill the sump close to the top.
