Tidal Mangrove Upgrade - your concerns

This is the tank I have now:

[20 long, dirt+sand substrate, mangroves, endler guppies, ghost shrimp]


I would love for my mangroves to shove out some nice prop roots, so I'd like to upgrade this tank to have tides. I really really don't want to strip this tank down, so this project can't involve drilling this tank or anything like that.

I don't want to mess around with pumps on timers, solenoids, or anything like that. I don't need perfectly replicated tides - just some sort of water level change that's enough to stimulate prop root growth.

So I came up with this:


Water is constantly pumped out of display tank into the reservoir tank. When reservoir tank is filled to a certain level, it is emptied back into the display tank by a bell siphon. If the bell siphon fails for any reason, an overflow drains directly into the display.

I am planning on using 3/4" PVC pipe.
Reservoir will be ~8 gallons.

Two questions:

1) I don't have a lot of time or money for projects right now, so I really want to make sure I get this right the first time. Do you guys see anything that could go wrong with this?

2) What's the cheapest way for me to make the reservoir?
- I don't have enough 1/4" acrylic to make the whole thing. Plywood sides?
- Can I use a store bought 10 gallon? Can those even be drilled?



Thanks so much for reading all of this!

Looks like a great idea (assuming it grows the roots) a bell siphon should work. Keep in mind your emergency drain can't be tired into your bell as it is in your drawing. For a container, a plastic tub or something similar would be easier to work with

Haha yeah, that was my intention - it's just not a very good drawing.

So unattractive though
I guess beggars can't be choosers.

I found an old 10 gallon that I drilled a hole in the side of a couple of years ago. It cracked a lot, but I somehow managed to completely reconstruct the panel with a big ugly glob of silicone. Might try the same thing for the bottom panel. Might also have to return to this forum soon for water damage remediation advice.

Mangrove tank - Reef Central Online Community

^^Sorry, I thought you might want to take a look at this RC thread. I don't think the OP actually utilizes tides for prop roots, but I don't really know anything about mangroves...

So many fish to keep, not enough aquaria.

Ahh, what a lovely mangrove reef tank! Those baskets are a little garish, but so much life!


Decided to go with the 10 gallon. My weakest water pump is too powerful - at lowest flow it still pumps in too much water for the siphon to break. I'm waiting on a 4.5 watt pump to come in tomorrow. Hopefully that will be slow enough.

I did end up cracking a side panel of the 10 gallon while drilling the overflow hole, but some liberal application of silicone and some acrylic scraps should hold it together okay... I think?

The tank stand is not my best work. Wanted to save money and go green, so I made it out of some bits of a bed frame I found on the street. Was a bit of a rush job, but it should at least keep the tank high enough for the siphon to work.
