Mike,
Sounds like what I have been doing albeit, not quite to the extreme that you took. I may have to though!
I have been pulling rocks one at a time to remove the algae. It is starting to cover the corals and I have to use a soft toothbrush to remove the algae from these.
Here is my Blog: Renman's Blog
Here is my setup:
225 gallon tank
100 gallon sump which has about 45 gallon refugium. (NOTE: Sump is algae FREE!)
Skimmer: Deltec 851
Water Movement: 2 -Eheim 1262 pumps to the tank.
1 Tunze Wavebox
1 Tunze Stream
1 SEIO 1500
1 SEIO 1100
Critters:
1 Sailfin Tang (5")
1 Swallowtail Angel (4")
1 Scooter Blenny
1 Oscellaris Clown
1 Pink Bar Goby
2 Blue Line Cleaner Wrasse
1 Tiger Pistol Shrimp
1 Gold Coral Banded Shrimp
3 Peppermint Shrimp
1 8" Black Serpent Star
20 Various Snails
20 Various Red and Blue Leg Hermits
Feeding: 1 standard frozen cube, shrimp/octopus/Brine Shrimp
Every other day, greens for the Tang.
Water:
Water parameters are good. Calcium is at 430, pH 8.4, Magnesium good, Phosphates=zero, I have to buffer quite a bit though...usually sitting at 6 DkH. Temp 78 degrees. Water changes have been every ten days at 65 gallons (~20 %).
Pat, I'm really curious about your methods? Sounds very interesting??? I would like to load the sump with more Mangrove plants for filtering.
My sump has lighting as I keep an overload of Gold Polyps Green Star Polyps and about 50 additional pounds of LR. The sump has lighting for about 8 hours a day and has great coraline growth! This is what is perplexing? No algae in the sump?
Here is a link to a reef care package that was suggested by John at Kingfish:
Reef Care Package - Reeftopia
I could host a meeting and get everyone's opinion on this? Besides, you have to see this killer tank with external overflow that Kingfish had built for me. It's plumbed through our dining room wall and all equipment is in the garage.
I could do this on Saturday the 24th at noon (have to work by 3pm) or Sunday the 25th?
