New tanks can be frustrating! The CO2 level looks good - 19ppm or over, assuming KH=10 or higher. You didn't say what your nitrAte levels are, but with that much light & CO2, there's a good chance they're 0 or near it, which will cause algae. The Flourish Nitrate has a calculator on the label to tell you how much to add to get to a certain ppm of nitrate - figure out how much you need to add to get to 5-10 ppm nitrate. You'll need to pay a little extra attention to the tank until you get it balanced - 50% water changes weekly, and manually removing as much of the algae as possible. What does the algae look like? hope this helps, Rachel ----- Original Message ----- From: RUDY STA ANA<mailto:rsta_ana@yahoo.com> To: aga-member@thekrib.com<mailto:aga-member@thekrib.com> Sent: Monday, October 20, 2003 8:39 AM Subject: [AGA Member] HELP W/ 180 GAL PLANT TANK Hello, Everybody! I am a new member-1st post- and started planted aquarium when you had your convention here in Houston last year. I converted my 75 gal fish tank to planted and after 6 mos grew Ludwigia and Stargrass pretty good w/ Carbo Plus. I thought that I needed more space for both plant and fish and thereby invested in a 180 gal. I had mediocre results-a little daily pearling and respectable growth on plants using Seachem Flourish a lot cheaper than Dupla 24 drops). I had to tear it down due to problems w/ tank that is covered w/ warranty. I had the replacement running for about a month now and have algae problems and non-pearling. I know or I think at least that the algae were result of adding Seachem's nitrogen and phospate. Since then only used Flourish, Potassium, and Iron - 10 ml ea/wk with 40-50% weekly water change. I have 480 watts of PC and 60 of reg flourescent(total 540) and pumps about 2 bps of CO2 gas. My tank has 0 ppm NH3 & NO2. PH=7.2 and about 10-11 deg KH & GH, Temp= 82deg. I have 5 3.5 in Discus, 10 o-cats, 20 Cardina J.,and 10 hatchets and 7 Corydoras. Can you guys help me out as to which kind and brand of ferts to use. Is my temp to high? Any help from anybody will be greatly appreciated. I am just desperate to grow a nice healthy planted tank. __________________________________ Do you Yahoo!? The New Yahoo!
