How many gallons do I have.

Ugh, even with my FC at shock level I'm getting all kinds of water bugs and, there is a slight yellow/brown tint to the water. I changed out the filter and the one that was only running for 24hrs looked like rust. Please tell me this is just dirt from set up. I have been having to scrub the sides and we do have red clay out here. Will try and keep it in shock level and will report back what the filter looks like tomorrow. If there is something else I should be doing before then please let me know. :O(

So, water clear finally this morning. FC- 13.4, pH-7.4, andTA- 150. Filter switched out and was rusty colored but a little lighter then yesterdays.
rechecked FC at 4pm and dropped down to 5.4. Adding 1lb Qiuck dissolving shock and will recheck in an hour.
