Hi everyone, First post on Reef2Reef!! I have been using this site for information for years but finally got around to registering ha! For my RedSea Reefer 170, I have been dosing Reef Fusion Parts 1&2 to maintain my Alk/Calc/Mg into the small bubble trap baffle right before the return pump...

I've never much used them so I don't know what's good, but I'm looking for something that's good bang for your buck that I could potentially plumb on a manifold. I'd prefer to have one pump for the return and another pump for running all my equipment on this build if possible. Preferably...

Hi I recently set up a new tank. Should be total water volume of around 650 litres when you subtract sand and rock. I want to purchase a UV to help with parasite control as well as water clarity. I have had Ich, Dino’s and cyano in the past. I am in the UK and torn between 4 different UV...

Hey all, PLEASE HELP so I have a 20 gallon long tank and have had a BAD velvet problem. Only one fish surviving. I have dosed with copper but hate adding chemicals to water. Would a UV AA GKM 9watt help eradicate velvet with my copper?? I know this isn’t the greatest UV for parasites, but since...

How much UV is produced by the UV bulbs used for aquariums, specifically the lights that sit above the tank outside the water? I worry about skin cancer and know how dangerous tanning bulbs are so am curious how safe the lights used for fish tanks are. I recently sat next to a large fish tank...

Hello Reefers. I have a Red Sea 425 XL 112 gallons total. Finally decided that I’m going to install a UV sterilizer for the purpose of keeping bacteria and parasites on the lower sides. I was thinking about getting an Aquatop E18. Wattage is 18 and it endorses that it can handle up to about...

Does anyone run the GKM UV sterlizer in a biocube 16 or 32? Where did you put it? I want to run the one with its own pump not the powerhead one.

Does anyone know of a UV sterilizer that will work for a biocube 16? I have been using the coralife one and it’s a piece of ****. The one on my 32 gallon works fine. This one keeps blowing bulbs or just not lighting period. Coralife even sent me a new bulb and nothing.

Looking for an Aqua UV 25W. Let me know what you have.

I had a bacterial bloom and after a full week I couldn’t take it anymore. I bought a UV sterilizer and in less then 24 hrs I could see everything again. All I can say is wow. Figured I share in case someone else is wondering how to get rid of cloudy water.

So, i just got the Aqua UV 57 watt for my 140g total water volume. The main purpose of this is for water clarity and prevent fish diseases. My main return Pump is 1900 and I measured my manifold rated about 1G every 35s so come out about 102 gph, in other hand manufacturer recommended more than...
