Hello everyone firstly if your taking the time out of your day or night to read this then thank you. I am on a journey in my life right now! we are buying a big beautiful house built in the 1920,s! it comes with already built into the yard a 100-200 gal koi pond! exciting yes I know that's what made us want it. however the yard isn't that big its pretty got a above ground garden trough built in the yard which my brain is racking ideas could I turn that into a pond/tank too or do I keep it a garden grow food or just some pretty flowers a lot of decisions to be made. however like I mentioned above the house its self is nice size I'm actually gonna get to build my fish room. like sure right now I have 8 tanks spread through a duplex but that's not a real fish room obviously! plan on turning my 135 into a community tank as a center piece moving the Large cichlids to the three hundred gallon pond for now tell I can afford and build my 2kpond in the basement the dinning room is gonna become the fish room do to its size and shape! cant wait to set it up and do some videos at any rate! for the real stuff in truth though I been in the hobby for a few years or more but I'm still a NOOB! when it comes to advanced stuff in the hobby. I run all my tanks in the basic ways most I have is canister filters I have tried to build my own using Cory's video but that's as advanced as it gets. I'm curious to know how one sets up an auto water changing system. do all your tanks have to be drilled to do so? secondly to that what system do I purchase and where do you recommend getting it from. if you know of a great video for the product your suggestion that would be nice too. I have used Cory's Wi-Fi plug so I assume that would be necessary as well to function the system its self. next subject would be floor testing as mentioned above the house was built in the 20's it has all wood floors from what I seen when i toured the house the floor's are made from 2x6 in most spots. however I question how sturdy they are as mentioned I want to load the dinning room with a bunch of tanks done some research your average 2x4 can hold 700lbs so do I just go down in the basement and put 2x4,s under all of the beams. with a house that old should i just get a bunch of actual floor jacks. the concern there is cost I'm not rich moneys tight and tied up in the house its self. and last but defiantly not least SOLAR POWER! for those of you that have a fish room large tanks or ponds etc. its no secret that when you start running that many big tanks in your home store or whatever you have. your electricity bill is gonna start rising along with other bills and I'm just wondering if anyone has converted to solar power if its possible if it would even be worth it. or if you have used any solar powered items in the hobby that you actually stand by. I only have used a solar powered fountain for my pond but it don't have a storage feature so only works when sun is hitting it but at any rate been seeing a lot of solar power adds getting emails etc. so truly has me curious if anyone has any experience with any of the above feel free to leave your input thank you in advance.
