Even though his face looked more messed up GSP was clearly outstriking Shields for at least 3 or 4 of the 5 rounds and was never in danger of losing. After 4 rounds of futility why didn't Shields or his corner try a different gameplan? Would have made for a much more entertaining fight.
I suggest first searching on the internet about contact lenses in lab. You will find different information there. There should be two sides to this policy. One should be whether contact lenses actually provide an additional layer of protection compared to someone without contacts. The other is whether a contact lens, once contaminated, will extend the contamination to a longer time than use of the chemical. These are both good points, but may not be something within your control, except to change lenses after lab. You might wish to read what you may find on the internet and then talk to the department chair. The last point I wish to make and I have no financial interest in, is the wearing of contact lenses. My wife had an eye exam and questioned whether her prescription may have changed. The optometrist questioned whether she should have lasik eye surgery. The point he was making was that lasik eye surgery had become safer than wearing contact lenses. The putting in and taking out contacts subjects you to eye infections and other injuries. He argued that in the long run, lasik was a wiser choice. I cannot recommend what you should do, but perhaps you should also looking into alternatives as well.
Pump performance drops off sharply with increases in the Total Dynamic Head. TDH is the sum of the static head (height of discharge) and the dynamic head (resistance of pipe and fittings). Only small pumps are measured in GPH instead of GPM. 125 GPM (7500 GPH) is not a small pump. Their instructions call for a 18 dia. basin 30 deep. I would not go less than 24x36 for a basin on that size pump. If the basin is too small, the pump will short cycle, and even with internal temperature protection, it could burn out in a few days of short cycling. Be sure to put some holes into the bottom of the basin even if you are filling it from a drainage pipe from the side, as water pressure from the ground will float the basin up out of the hole. The weight of the pump is not enough to hold it down, in most cases. Be sure to drill a 3/16 hole in the pipe between the pump and check valve, preferably just above the pump discharge outlet, to prevent an airlock from damaging the shaft seal. It also needs a dedicated 15 amp circuit, with nothing else plugged into it. Personally, I would go with a Zoeller model 292, for that application, but the price would be much higher for a pump of Zoeller quality. They also have excellent technical support.
