It's too early on a Sunday morning, so I'll leave you to do the math. At 1/10 the size of your tank, with basic EI dosing, you'd use 3/4 tsp KNO3, 3/16 tsp KH2PO4, and 3/16 tsp CSM+B, per week.

Don't buy a package deal - it doesn't make sense if you know the proportions you'll actually use, which is 4x more KNO3 than anything else. So, the ratios you'lre looking for would be:

4 KNO3
1 KH2PO4
1 CSM+B

And if you'll be using KSO4 and/or GH Booster (neither may be necessary, and using both together is definitely not necessary. It depends on your water):

1 KSO4
2 GH Booster

This is where you have to find out what your tank needs since all tanks are different. For instance, I found I need NO KNO3. Due to fish load, I get plenty. For the starting tank, I suggest going with a pound of each rather than loading up and finding you never need some of it.
A bit of a gamble either way if you have to have ferts shipped. Do you want to buy something you may not need or buy too little and have to reorder quicker and pay shipping again. As I waded in, I found there were other micros which I needed to order any way and combined the shipping.

Looking at prices between the dry and liquid, I feel the dry is so much cheaper, I can cover any miscalcualations on amounts and still come out ahead.

Buy 2 lbs.

1) Put it in smaller containers, 2 separate 1lb bags, or 4 x 0.5 lb bags. Less chance of spilling it all, getting it all wet, etc.
2) Label the bags/containers CLEARLY! Once they aren't marked, identifying most of them are going to be impossible. GLA uses finely ground ferts(last I saw) which is great as they dissolve fast, but they lack grain and texture like the agricultural stuff they are made from and thus harder to guess what they are. I see people take the stuff out of bags all the time and forget to label correct. If you put them in containers with lids, label the container AND the lid.....

3) if you find you don't need as much, you can sell it in the SnS easy peasy. Air tight, it'll last longer than you need it to, so no worries. Since shipping is a bulk of the price, silly to have to reorder in 8 months if you could have saved that 15 bucks up front.

1 lb of each may be enough with one tank. I have more ferts on hand, but I have about 2 dozen tanks, and fertilizer roughly 1000 gallons of water.
