Hey Kharn, obviously you have an awesome system, and the idea of multiple mantis' in one connected system could intrigue anyone, as I certainly have been. If you dont mind me asking a quick question to you and everyone else viewing the thread. Were there any other tank ideas that had went through your head before deciding on multiple tanks sumped together? IE: one really large/long wide tank..sorta like a frag tank with acrylic sheet dividers to seperate 5g, 10g, or larger sized sections? Reason i ask is, i have access and can get many smaller species of mantis around here. Only problem is my parents limit me to two tanks total. allready have my 34g acrylic peacock tank in the works with a divided 40g breeder sump/macro fuge for my gt and one other medium smasher or a p.ciliata, but i really want some sort of show/display/multi container system to have some of the smaller species (wennie, smithii, what i believe to be my current viridis, andthese smaller species lined up, all in one stable system without plumbing? Ill soon make my own thread, just thought it was relevant and curious about what otherplans you might have had that was not posted on this thread.
Firstly I don't know what you have read but all my tanks are NOT sumped together although some have suggested I do it as I am in the process of a MAJOR filtration upgrade, even so I have decided how I will upgrade and it will not be all on a single sump.
Looking back on what I have currently and what I could of had (instantly stating, yes, I did do things wrong / could of done much better). There are many things...initially I didn't want to have any coral in my tanks, that soon changed 6months later, so the filtration setup which the stands are designed around was very basic and in that sense...strict to modifications (upgrades) a GIANT flaw.
Each STAND is a 'Lone' System effectively giving me 3 separate systems, the primary reason I connected the tanks in the stands is to increase overall volume per tank, thus each STANDS total water volume rather then each single compartments is what maintains the great stability (the smallest STAND is just under 200L).
My flaws...how I connected each tank, I think at the time I was just so excited about my idea happening that I just wanted it to HAPPEN, so I neglected fairly simple plumbing mechanics...simply put, the tanks in 1 STAND are connected via a single/1 bulkhead 32mm dia plumbing, water fills the top tank and travels down to the middle then the middle fills and goes down to the bottom, in 1 of the bottom tanks compartments is the INPUT of my Large Canister Filter (FX5) where the water is sucked back into the canister and filtered (at full open suction) then forced out at about 1/3 strength into the Top Tank of the STAND...it's fine to reduce Output from canister but not INPUT to canister from what I read, but the point is, the flow from the filter has been severely limited, if I increase it, the Top Tank will overflow because the single 32mm Bulkhead cannot handle more then what it is doing rite now, same goes for all STANDS.
What I should of done...as I did my research AFTER I made it all and had it running...was do a whole back wall overflow, basically making another very slim compartment rite along the back of the tank, the surface skimming is the best and the flow could be anything I want it, also the tanks would drain directly down from each other, top straight down to middle etc. at the moment the pluming connecting each tank is on the sides of the aquariums and more importantly...not above a tank meaning water goes on floor if plumbing gives...bad idea.
Dividers had to be tough if not 'impervious to stomatopod invasion' as I put it to the tank makers, from what I had already witnessed with only my smallest species (all under 125mm) and what was backed up by reading and questioning researchers like Dr.Caldwell. More importantly from what I had witnessed first hand many times...stomatopods are insatiable artists of escape, they will test EVERY nanomillimeter of their compartment for a "flaw" and to date they have ALWAYS targeted a place that already has a hole...A.K.A a water flow point...even my heavy duty containers needed flow...the holes were small but every one was tested as evident from the chipping/frosting from the tiny cracks...slowly but surely 1 was picked and slowly made wider and wider until escape, even now my female G.graphurus daily bashes on the egg crate dividers separating her from my Male G.graphurus, there are 2 sheets of set to cut the squares in half and reinforce the divider, she managed to get through somehow...as she is now holding eggs, the egg crate is just mangled on her side from hits...on his side their a large pieces missing but he doesn't actively do it (rather rare these days), eggcrate won't stop them, it will slow them down/give them a challenge and leave you paranoid...
It's very hard to lock down the smaller species in compartments with possibilities of escape...
The most important part that I should of done as I stated was filtration (which I am now going to fix, tremendously...) plan is to get Rid of the FX5's and replace them with effectively...a second set of STANDS positioned directly behind the DISPLAY STANDS & at the EXACT same dimensions of THEIR DISPLAY STAND (1x STAND 2ft L | 1x STAND 3ft L | 1x STAND 4ft L) the filtration...(besides live rock).
Current...per STAND
1x FX5.
Upgrade...per STAND
1x Skimmer in sump.
2x Reactors in sump.
2x Refugiums, refugium to be same size as DISPLAY TANK it's behind.
Essentially the DISPLAY STANDS will get the exact same volume added to it (doubling it) but the added volume is all filtration and equipment sump & 2 refuigums, all 3 sumps being the same size as the DISPLAY TANKS they are behind.
People think I am MAD:bigeyes:then I show them a video and they question their own sanity:lol: "WHAT IS THAT!?!?"
