Hey Tom I just read an article about raising your ph to 8.5-8.6 for an extended time kills off briopsis algaes also raised mg to 1500. Do it over a couple days and skim heavily is what they said. Give it a try it may work on this as well. the article is on MD's forum
Thanks Husker. I have a couple more tricks up my sleeve before going that route but I will keep that in mind.
I'm giving an update on my water mov't from a "hint" from another thread...lvpd are you there??
I installed a Vortec about 3 weeks ago. To say the least very cool pumps. I thought I would give a pro/con report (my opinion only) on Vortec vs Tunze Stream pumps.
Vortec
pros:
nice wide gentle water mov't
low profile look inside the tank
low energy consumption
ability to move anywhere in the tank with the magnetic attchment
low heat added to the tank
speed controller is included
Cons
even though the water mov't is very wide it doesn't push water very far down the tank like a Tunze
Some mention that misaligning the prop and motor can cause vibration although I have not had this happen to me and I have moved the unit numerous times.
Tunze
pros
Moves water further down the tank.
larger models are available for larger tanks to move more than 3000 gph
cons
very large size to mount in the tank (as you all know a pet peave of mine)
heat added (although a small amount)
wires hanging in the tank
So you may ask what have I decided? Well I'm going to do both Vortec and Tunze in my tank. I am going to run 2 Vortecs and a couple Tunzes. I just ordered another Vortec and another Tunze. I'm going to place the Vortecs on the back wall and place the Tunze's to blow down the length of the tank. So far I roughly figure that I will have 16k gph of water mov't in the tank or about 38 times per hour. In time I hope to increase that even more as I get some coral growth if needed.
Hope this helps.
