My tank is 75 gallons with a 20 gal sump about 5 yrs old. I have cheato growing in sump with 2 x 4" socks. My skimmer (Omega 150) kept overflowing back into my tank so I don't use it. My return pump turns over the water 10 x per hour and I have a Vortech MP40 for circulation. My light is a powerful LED made for plants. It replaced my 2 Blue Aqua Illumination lights. I change 5 gallons every weekend and use reef crystals. I Kalk with top off and manually dose mag and strontium every few days.
