I really liked the Red Sea Pro kit for Ca, Mg and Alk. The Algae Control test kit for NO3 and PO4 on the other hand, was less than acceptable. Ultimately I would recommend getting a Hanna checker for PO4. The NO3 kit would work, but there seemed to be a large amount of particulate matter in the...

Looks like cyano bacteria.

What size and type, i.e. side by side, top freezer, bottom freezer, etc.? I subscribe to Consumer Reports and can look up what they recommend. Budget?

Congratulations to the new board, and thanks to the previous for your work and dedication.

If there is a spiral look to them they are possibly Spirorbid worms. Nerite snail eggs obviously look like small white sesame seeds.

Does the refractometer have an auto temp correction, aka ATC? If so, let it sit for about 30 seconds before taking the reading. Although, considering these are hobby grade test equipment, and there is a certain margin of error, I think either reading is close enough for our purposes. Probes, and...

Either should work fine if properly calibrated. Just use your make up water @ 1.026 for your top off until you get your DT where you want it, and then go back to plain RO/DI.

What is the process to "harvest" the algae that has grown?

I used to use four old vingar gallon jugs for this purpose, two in use and two in waiting, and when I needed to refill them I just switched them out. I did, however have an issue with the sediment building up in my 5 gal. ATO bucket, and was working on a CO2 scrubber "breather" for the lid...

I continued using Kalk even when I started dosing two part. Like you, I would make the kalk the day before, allowing it to sit overnight, and pour the clear settle kalkwasser into my top off container the following day. I used two tsp. per gallon of Mrs. Wages Pickling Lime(I think it has fewer...

You might want to consider the sales cycle too, most sales people are driven by monthly and quarterly quota's, and as such are more inclined to be more flexible at the end of the month/quarter to make their number.

I would stick with one of the Bristletooth species for that size tank. http://reefkeeping.com/issues/2003-07/hcs3/index.php

I had a similar problem with the Jager heaters being too long for my sump, and went with the Hydor THEO's. I was able to go to a 400W heater, and save ~ 4" in length. I did, however replace them every couple years, and move them to my WC station where they took a beating, and never broke. I used...

There's been a lot of posts on RC regarding the Hanna Ca checker being problematic, and for that reason, I never used one. It might be prudent to get a second opinion on the Ca with a different test kit. However, I did use the Hanna Alk meter and was happy with its performance.

BRS sells the canisters.

Any 10" replacement cartridge will work, so typically BRS, Buckeye Hydro, Spectapure, AWI, etc. What is your raw water is like, i.e. well water, city using chlorine or chloramine? I would also suggest you go through the sterilization process here:

Cobalt's are on sale at BRS @ 15% off. Sorry if it's too late.

You might try Grainger, or Tractor Supply.
