Default NFT System

This is my 1st system, it's been great for working the kinks out, it's not very neat or efficient but I'm happy with the 1st setup.
I used a 100 gallon old livewell with a 90watt pump, my troughs are aluminum, 10' lenght, 1' width, 3" sides, I raised it up with lumber I had laying around.
I keep two separate 32 gallon rubbermaids with nutrients and use a hanna 98129 for PH and EC measurements. I seeded 32 tomatoe plants, 8 brocolli, basil and a some other herbs. I seeded on 3/15 and started picking fruit in June. I had some problems with blossom end rot, I doubled my calcium nitrate and it solved the problem.
I live in Florida keys and have been at war with the iguanas. I used 2 different tomatoe seeds, determinate, bushsteak and super tasty hybrid I got from Burpee. Both are great tasting and a 1000 times better than the grocery store fruit.
I've had problems keeping the nutrients below 88, it's affected yield. Our tap water is pumped in from Miami and very alkaline, 9.8 on my tester. I just use nutrients to lower PH. My daily measurements are PH, EC and temp.

Next week I'll be breaking down system and will re seed in middle of august. My system will look much different when I rebuild, I'll be going two tiers high and much more streamlined with sun shade. I've attached 3 photos, any feedback would be appreciated.
