The CRYSTAL series sumps have the same design and quality as the RUBY series sumps but are made of all clear material. The differences when compared to the equivalent RUBY sump:
- Same or slightly smaller dimensions
- All clear material instead of the RUBY red
- No probe holder
CRYSTAL SUMP models come with dual platforms in the space before the return section. The top platform comes with a foam block filter and the bottom one is open to use for several different filtration methods (bag of carbon, bio balls, rubble rock, etc.). This feature is on the SUMP models only.
Locking Filter Sock Holder
Filter socks snap and lock into the filter sock holders to secure the filter sock from falling out when it becomes clogged and needs to be cleaned or replaced. The 4” filter socks are 100 micron rating.
Draw String Tabs
Tabs are located on the top support brace in front of the 1” bulkhead fittings which are included. The purpose of these tabs is to provide a location for tying off 7” diameter filter socks that have draw strings.
Trigger Systems specializes in aquarium sump manufacturing. They take pride in the robustness, efficiency of the design and visual appeal of our sumps. All sumps come with a full top support brace which are made of a solid piece of material. Without this the sump will over time begin to bow out from the humidity and water pressure. We also round instead of squaring the corners which exponentially increases the strength of the corner.
Trigger Systems has taken feedback from their customers through the years to enhance their line of awesome sumps. Little things in the design aspect will pay off considerably when putting the sumps to use. A simple example is that they always maximize the distance between the protein skimmer location and the return pump in an effort to minimize the chance for micro bubbles returning to the display.
Gets the job done By Clifton on 6/8/2018Clifton would recommend this product to a friendIt's well constructed and had nice appeal for systems that like to show off the sump. Nothing fancy but gets the job done.
Solid Sturdy CRYS36S Sump By Jassimps on 12/13/2017Jassimps would recommend this product to a friendI purchased this sump for 75 gallon rimless build going on 3 years now. I like the all clear material plus it's a simple design. I use it as a refugium style sump with an oversize skimmer in the middle. The matching 5gal ATO is a nice addition too. Purchase once with confidence knowing that it's designed for the long haul.
Skimmer compartment By david on 9/16/2017david wouldn't recommend this product to a friendIt's a well constructed sump the skimmer measurements are not 12x13.5 with the sock area measures 11x8.5 I have a skimmer 7.5x7.5 barely fits the socks sit behind it which isn't very easy to get to
Great Sump By Thekekg on 2/17/2017Thekekg would recommend this product to a friendGreat Sump feels sturdy and solid. no complaints. Price is a bit high considering it really doesn't do anything special other than hold water but all sumps are expensive unless you feel like doing a DIY.
Perfect. By Michael on 2/13/2017Michael would recommend this product to a friendPerfect in every way. Good size refugium, large skimmer area. Plenty of space for extra pumps, heaters. Etc.
What size tank is this good for?
Our recommendation would be to pick out your display tank and stand, then get the biggest sump you can fit in the stand.
have a great day!
How thick is the acrylic and will it bow out over time?
This acrylic will be around 3/8" thick depending on location and from our experience doe not have much bowing in the several months we have had them running. Feel free to let us know if you have any further questions!
