Hello, This question regards a 275 gallon tank. Tag info is 10 10 275. This is an old tank.

Tank has dry bottom want to adjust delivery schedule so that a minimum of oil is stored in tank.

Thinking tank should not be filled to more that 1/4 of capacity. Even at this it's still 70 gallons. Too much oi to have in an old tank.

What delivery schedule should be requested to have as little oil in tank & not run out of oil during winter?

A slow fill has been requested. Will a low oil level cause the sludge to be dislodged & churned up on delivery ?

Is it possible that the sludge is sealing pin holes in tank ? Don't want sludge clogging filters.

Does anyone know of a method of containment that can be used on this tank ? How would this containment system seal tightly around the 4 leggs & bottom discharge pipe to contain the ever rising level of oil inside the containment as tank drains out ? Is there a company that makes such a containment ? Thank You.

Is it a good idea to use a biocide in an old tank that has never been treated in the past?
