I am kinda in a tough spot with my tank, I have no way to gauge my iron & phosphate levels. I am afraid that they maybe low. Is there any solid way to determine this without a test kit? My wife had pretty major surgery a few weeks ago, & hasnt worked in 2 months, that along with the time I have had to miss due to her surgery being out of state, has us in a financial bind, so the kits, no matter how cheap, arent really something I can pick up.
Any advice on what to look for?
