gehajake,
Yes, I agree that taking the time to set up an irrigation system from your tank will save you a huge amount of time in the future watering blueberries and trees. I think you will achieve "payout" for your time in about a week!
That filter screen I linked is usually in stock at our local Home Depots.
I have installed battery timer valves on my far-flung tanks. For the tanks close to my normal work routes, I just open the tank valve and hit the timer on my phone.
For people that do not have AC electricity at their pond or water source, I have had very good luck with the cheap 12V submersible sump pumps from Amazon. They are capable of producing a good bit of vertical lift. I can do multiple tank fills over a 2-week period with a deep cycle battery. A solar trickle charger would probably allow me to use the battery for 9 months without ever taking it in for juice on the AC charger.
My advice would be to get a tarp over your tank ASAP. If using an IBC tote, you could probably even wire scrap plywood to the top and sides of the metal frame. If it is too ugly and in sight of the house, let the kids/grandkids paint a picture on the plywood before you attach it. Blueberries that they "helped" grow will taste even sweeter than regular blueberries!
