I purchased my 60g tall tank in March 2019 new from local fish store. I had it up and running nicely until April of 2021 when I fell very ill with cancer and no one was around who could care/maintain my tank. All the fish and the live plants sadly perished and the water evaporated out of the tank leaving dried on plant matter and dirty gravel as the only tank inhabitants. It has sat in this condition in my living room since. I have finally finished cancer treatments and am finding the energy to get my house chores caught up and I have now taken all the old plant matter, gravel, decor out of the tank. I have a steam cleaner I plan to use to clean the tank but it's too tall for me to reach into the tank to the bottom without putting my considerable weight on the top rim of the glass since I'm only 5' 2" tall and the tank is 25" deep and is on a 39" tank stand. I'm hoping you all can give me some advice on how to get my tank back to it's original beauty. my biggest questions are 1. can I lay the tank on it's side so as to use the steam cleaner to clean the glass without causing damage? 2. Would it be better to lay a moving blanket on the tailgate of the truck outside to use the garden hose to spray out the heavier debris first so the water can be dumped on the ground? 3. Can a mixture of Lemon juice and Vinegar be used as a fish safe cleaning agent? I have seen mixed reviews on this one as some say that both lemon juice and vinegar can be added to a tank for PH issues and some say DO NOT ADD these to a tank implying that it's not safe. Can someone please clarify keeping in mind that my tank will be cleaned, then left to dry completely and then I plan to use CaribSea Eco-Complete Planted Aquarium Substrate in the new setup and I plan to plant live plant seeds in the gravel and allow them to germinate before I fill the tank with water and then I will need to recycle the tank before any new fish are added. My original cycle on this tank also took 2 1/2 months to complete its initial cycle because of its size and that was with Biospira bacteria added and gravel from an old tank to help it cycle
