Aquarium Choice Acryli Made Liquid Storage Bucket Dosing Pump Reservoir Container (4.25 * 4.25 * 6.5 Inch;1500ml/1.5L（Blue Version)

I don't know why anyone would buy a more expensive product that is designed to do something so simple. It works great and seems very durable!

Markings on side, low bottom point of suction, and came with tubing.

Mine came with a bad leak. Also the smell of glue or whatever they use was pretty strong! Guessing these are all coming from the same source and probably luck of the draw. Test yours when you get it and if you keep it, reseal the hell out of it. Returned after testing and found the leak

I would order this again, plastic is crystal clear

Using this on a reef aquarium for dosing my pH. We’ve been using for three months takes a little while to get dialed in, but you have as function perfectly. The app could be a little bit better but overall at the price very good value.

Good: solid construction, included hoses (3) are good quality and seat well (a little odor, but fades quickly), compact size holds 1500 ml (50+ oz) usable in each section, graduation marks etched into acrylic.Bad: DRAWS AIR from unsealed stem to fitting (see modifications), stems are a little short (fill above the line to get full useful volume).I got this for aquarium supplement dosing, for use with the Jebao DP-4 dosing pump.After unpacking both this and the pump and hooking them up, I noticed that the fluid would draw up the stem, but very little made it through the pump.Turned out that the stems aren't sealed to the nipple fittings, so air was being pulled into the line so the pump wouldn't stay primed (even when I filled the lines first).MODIFICATIONS:To fix the above, I unscrewed the nipple ftgs with a 14mm wrench, found that the stems easily came out from the nipple ftgs, and decided to glue them together. I didn't have any acrylic glue or PVC pipe glue so I used some coral glue (cyanoacrylate) on the end of the stem and inserted into the nipple ftg. I also put a bead of glue around the joint and wiped the excess with a swab.Testing after the glue set worked great: much faster fluid draw up the stem, and the stem didn't drain after the pump shut off (lines stayed primed).I still think the stem is too short, but I can still get the full 1500 ml useful volume as the container has some extra height. I could add an extension, but small amounts of the supplements can precipitate out of solution, so it's better to have a little room.

this dosing tank is beautifully made.. and the design is 'spot-on'... the lid does indeed seal so well by just sitting in place that vac-lock does occur, but a small hole drilled in the lid, or even installing a tiny air valve can mitigate this aspect!!!definitely will be buying more of these....

I purchased 2 of these for use in a robot bar-tender that I am building. I was concerned after reading some reviews about people receiving theirs broken and leaking, and the issues with the connectors. When I received mine - it was packed extremely well - in a box with high density foam padding surrounding - with double layers on top and bottom. I did a leak test with no issues. I also had no issues with the plumbing when using high volume peristaltic pumps to draw water and sanitiser through the tubes.Two things I would change about these - realising that I am using them off label - would be to have seals for the lids and to sacrifice some volume in the tanks so that they could have a vertex drain where the outflow tube would attach.
