This is the one I picked. It's rated for up to 150 gallons, and can hang right on the back of the tank if there is room.

Have you ever checked the water you're getting from the LFS? It's been my experience that many LFS's aren't really giving you water that has been processed through DI resin. I also found out that the LFS I used at one time wasn't very diligent about replacing the filters either. Do you know someone nearby that has a good TDS meter, that would check the water you're getting from the LFS? I'd invest in a good RO/DI unit, and TDS meter. Considering the WC's you should be doing and the amount of top off you need, it would pay for itself in a relatively short period of time.
Alk in both tanks is extremely low.
simply its a nutrient issue. 5ppm and 2ppm phos is crazy high u needa to run GFO ASAP. also your nitrates in the big tank are high at 30ppm other tank at .5ppm is fine. as other have said run a gfo reactor and sume chaeto in a fuge or biopellets in a reactor will take care of both nitrates and phos. biopellets take a while to get going for now u need to run some gfo. as high as your phos are the gfo will get exhausted very fast and need to be changed in a few days- a week till you get them down to .02-.05 using a hanna checker preferably to test. after maintaining low nutrients the cyano will go away and wont return as long as you keep your params in check.
In the future what should I run after its all under control? Biopellets or BRS High Capacity GFO? Ive also been doing a 10 gallon water change every week.
ive never tested my LFS water but im about to now. What all should I test for? Wish I had someone close by, but the closet store is a hour away. The RO/DI unit I just bought from BRS has a built in TDS meter so that should help me. You want the closet to 100% on your TDS correct? Thats why I decided to buy one. Was spending $50 buxes almost every week on saltwater and ro water.
What should I do to raise my ALK up?
Here is an excerpt from the link I posted on page 1 of this thread:
"Antibiotic Control Cautionary Remarks
There are numerous products promoted as chemical controls of BGA, some erythromycin antibiotic based, others of copper, sugars, even pepper sauce… All should be avoided on two counts: Though they (the antibiotic based ones) may apparently work, the materials that make up the BGA frequently poison the system within minutes to days of their "dissolving". And, adding insult to injury, unless you change the circumstances/conditions in your system, the Cyanobacteria very often "reassemble" in a short while if chemically treated.", Bob Fenner.
