Red Sea C-Skim 1800 Advanced Protein Skimmer There is one on ebay for $195 but does not come with a pump It says that it can be a "in-sump use or stand-alone installation". But not sure how it could be stand-alone without a tank of water? Since the output would need to go into a tank and be...

So I want one rated for a 150 to 200 gallons tank and an air draw or LPH of 800 to 1000? Notice some are rated as internal and external. Are the internal ones that sit in a tank (sump) under the tank and the externals hang on the side? Found this one but it is expensive ($803) Vertex Alpha...

So if I have 100 gal (dreaming of the future) I am looking for a sump rated for a 150 to 200 gallon tank. How do they rate "air draw"? What would I look for? Thanks

I have a Dual Bak Pak 2 but only one side is working. I thought one side was good enough for my 55 gal. I guess I should get the other side working again. Would that be a big enough protein skimmer for a 55 gal.? How many gallons would you change weekly on a 55 gal.? I've been doing 5...

No sump/fuge but I do have a protein skimmer. Would you go with a wet/dry filter?

What would be your perfect filter for a 100 gallon reef tank set up with hard/soft coral, sea anemones and just a few fish? (Try to keep it under $300) I have a Magnum 300 canister and I guess it might be contributing to my Algae problem. It is not the easiest thing to clean/change out. Also...

Coraline Algae I think it is Coraline algae the stuff that flat and hard comes in different colors and grows on rocks and on the glass.

Coraline Algae ALGAE! and its eating my calcium! Reminds me of the time I thought I had a beautiful sea anemone and was painstakingly feeding it. You can guess what it turned out to be. AIPTASIA I think I might have a little hard coral that kind of looks leathery on some of my rocks. Just...

GFO Just watch some YouTube videos on GFO/Carbon Reactors. So they are not filters they are an addition to a filter right? I was wondering do you think I could add a bag of GFO to my Magnum 350 filter? Maybe I should add 1/2 carbon 1/2 GFO to the magnum to prevent clumping of the GFO?

Otto Is that a saltwater fish?

Algae What is the difference between soft coral vs hard coral vs sea anemones? Sometimes I see pictures of what I think is a sea anemone and it is a soft coral. I thought since I had live rock there are corals (the colored purplish stuff that sometimes grows in spots on the glass) on it. So...

Problems with Algae and my plan (tank 1 year old with live rock stacked to the top) 1. Change to RO/DI water not tap water.(DOING) 2. Don't over fed (no fish yet just debris eaters) so that won't be hard 3. Keep lights on only 10 hours (is that to long?) 4. Improve water movement - stack...

My dream filter would be the Fluval 406 even though my tank doesn't need that big of one (55 gal). I thought I might get an 100 gal someday and would want to be prepared.

PH rising Added the salt to some of my RO/DI water and the PH was 8.2 YEAH Can't wait till the whole tank is up to 8.2 Thinking about a UV sterilizer to help with the algae problem also. Any thoughts?

Forgot to add, I am using the PH test where you put 5 drops of the testing agent in 5cc of water and compare the color.

I thought the RO/DI was supposed to help raise the PH? RO/DI is actually lower in PH then tap water? What is IMO? Raising PH is complicated I guess. So when I add the salt to the water it will raise the PH in the RO/DI water MORE then if I added it to just tap water because the tap water has...

I have a 55 gallon aquarium with live rock stacked to the top. It's been running for about a year but no fish yet just a few snails, crabs and a sea urchin and a brittle sea star. Specific gravity stable at 1.024. I have been having an algae problem and a PH problem. So I purchased a RO/DI...
