Here was my original issue: I'm getting ready to set up a 31 gallon saltwater/reef aquarium (the beginner's Biocube) - problem is that it requires that you use RO/DI water. Besides filling it you do have frequent enough water changes and you need unsalted water for topping off (salt doesn't evaporate so you top off with pure water rather than salt water but you do water changes with a salt mixture). I also have 2 tanks of freshwater fish. One soon to be 90 gallons tank and one I currently have that is 50 gallons (I'm retiring my current 29 gallon once the 90 arrive). I also have to doctor my water as it's going into the tank (I've killed fish using the Python for that very reason), one chemical lowers my tap ph of 9.4 to a solid 7.0 IF you get the precise amount. I don't dare risk dumping PH 9,4 water on their heads even temporarily. The other of course, is a water conditioner (Prime). Saltwater also must be mixed in advance and not in the aquarium itself. So we had water problems.
You can buy that much water in 5 and 10 gallon containers but I'm on oxygen 24/7 and rarely even drive. Not an option. My assistant has back problems thanks to all the water changes he's done for me and my freshwater tanks. I have back problems for the same reason plus poor bone density and degredation of my lumbar vertebrate (his is a slipped disk). We've been hauling way too many buckets.
My solution (I thought I was such a genius until I started noticing this same set up in a lot of youtube videos - so it's probably a "duh" for most of you, but for those like me that try to make every problem seem too difficult to solve or are just plain stupid - I hope you like my solution
I purchased 4 Rubbermaid BRUTE trashcans and lids (20 gallons). Brute cans are certified FOOD SAFE and do not leach plastics into the water. I think after moving water in these and almost tipping them multiple times that 20 gallons is a nice safe size to move water with) We don't use the lids unless storing the water.
I purchased 4 rectangular dollies (couldn't find round ones at any reasonable price) to put the trash cans on.
One is our "dirty water trashcan" and dirty water of all types is siphoned by 1 or more Laifoo Aquarium Water changer ($12.99 on Amazon). For big tanks the more the better and the suction bulb does tend to wear out every 6months or so we have 3 of them. The water is then moved to the nearest toilet and dumped by smaller buckets into the toilet - yes, still buckets but we didn't have to carry them through the house. Originally our plan has been to dump the water outside (great fertilizer) but we can't fit them over my doorframes - going to try a rubber mat over the door frames next time I do this and see if that gives it enough slope to slowly move them across without tipping over or spilling,
A second trash can is for mixing our freshwater from the tap of the kitchen sink (pure water lacks a lot of essential nutrients - that's not a problem with salt water because the salt mixture you purchase adds the nutrients needed back into the water at correct levels - wish they had something like that for fresh water fish. So we just get it out of the tap with an adaptor on the kitchen sink and a 5ft piece of water hose (human grade safe for drinking and no leeching of chemicals) The advantage of using the water immediately is that you can get it close to the correct temperature.
Two trash cans are for me and my salted and pure water - I purchased a $159 portable RO/DI water maker - supposedly makes 100 gallons a day of pure water but in reality I'm told to expect more like 50 on a long full day - plus it only fits in my kitchen sink and I need to use that sink sometimes).
I plan to make and store 40 gallons of salt water in my two trash cans and use it to fill the 31 gallon tank with some left over. Then I'll rinse out the other one A LOT in the bathtub and use it for pure water after that - I only need more than 20 gallons of saltwater the first time I fill the tank and in reality probably much less since the substrate and a reef will be in there - so 20 might actually do it. After that point one can will be designated "salt water" the other "pure water" and my assistant and I will share the dirty water can with all tanks.
We've started using this system for water changes for the last few weeks and it makes them 100% easier and takes nearly half the time. We believe in big water changes -(I tend to overfeed and we have some big pooper fish). So we're removing 70-80% of all the bad water. With multiple siphons going that is done pretty fast. I may have to get another trash can or two. The first part though is still vacuuming and that takes quite a long time, but even in the 50 gallon I have it well vacuumed before all my water is siphoned - I can imagine us needing to use 3 siphons for the 90 gallon,
Once my saltwater tank becomes operational I'm going to have to preheat the water in trashcans without burning the plastic. Any ideas on a good heater or technique? I want to at least get it CLOSE to the correct temperature of the tank water.
So am I brilliant or what? Once I start on the salt water tank I'll know for sure. I sent in a question to Rubbermaid about where EXACTLY is the 20 gallon mark on their cans so I don't have to measure my pure water - I'm hoping to just have it move straight from the hose on the kichen sink into the cans without having to wait for a gallon to be produced (that would be a LONG day). You almost always have to tweek your salt levels a little I am told but I'd like to get the right concentration pretty close on the first try.
Unfortunately the cans are rather ugly to store - but you can get them in multiple colors so have some fun with it. I have a dedicated fish room and they all fit - we have to move things around them a little sometimes.
