Are you saying that Ushio DE 10K is now the same as the BLV 10K DE that Sanjay tested?

Having a hard time locating BLV bulbs. I'm specifically looking for the 250W DE 10,000 K. I see some places list Ushio/BLV bulbs, but the Ushio 10Ks are difference than the BLV 10Ks. thanks

I have a GRI 520 on a closed loop. I am considering having the pump turn on and off with my lights. Does anyone think this will cause damage or significantly shortent the life of the pump? Thanks in advance.

Louey, Thanks for the reply. Last night I spent ~1 hr looking through the online McMaster catalog. I found the gasket pages, but couldn't tell exactly what I was getting. I am like a kid, pretty pictures help and McMaster is a no frills website. I'll give it another try. Anyone else order...

Hello All. I don't post often, but I could really use some help. I am building a new calcium reactor and I would like to manufacture the bolt-on type flanges seen on most comercial units. Where can I buy the gaskets? Where can I buy "hand tight" type the Nylon screws? I have seen the hex...

This month's aquarium is my all time favorite. A man after my own heart. Does anyone know what a decanter is? I couldn't find Reference 1: Tout savoir sur la sédimentation Joffrey Dislaire Aquarium Récifal - 2001. Not that I understand French, but I figured I could decipher any schematics...

Another good reason to wait....I read once that excess dissolved CO2 can cause your sand to fuse together and form hard clumps. This is less likely to happen after the tank is established and the grains are thoroughly coated with bacteria, etc. I did not think to much of this warning and...

esmithii brings up some good points. In the absence of photosynthesis the O2 production decreases and consequently the pH drops. Less water movement could amplify the nightly pH swing. With a refugium illuminated at night, the pH swing is controlled and I doubt the decrease in closed loop...

A few thoughts: I have considered doing this also. I know for certain the reefs and beaches I have frequented are much less windy at night and in the early morning, but I am no oceanographer. Any surfer will tell you that wind contributes significantly to the wave action near shore. (a side...

golfish, thanks for the reply. I am not really concerned about there color of 65k's. I am one of those guys who actually likes it. I am more concered with the performance and longevity of the DE 10k. I would just like some conformation that Sanjays data is correct -- the 250 DE bulbs have...

No, I don't want to start another endless debate about the merits of DE vs SE…. but I fear I might. I have been a loyal 400w iwasaki user for some time, but my new smaller aquarium will incorporate one 250w supplemented with 28w PC's. I laboriously read most of the threads I could find on...

I am in search of the John Guest speedfit valves and stem connectors used on the EcoTech Marine Nielson reactor. These are very handy valves that snap right onto 1/4" OD vynl tubing. Let me know if you have any suggestions.

I am almost done building a very nice kalk reactor, and I need to decide on a dosing pump. I need quality, reliability, versitility, longevity, and all the other "ity's" you can think of. Thanks

Hello all, Does anyone dilute vinegar in their top-off water before it is fed into a nilsen reactor. I have been considering it, just looking for some feedback. thanks
