Sea Lab no 28 blocks - kilo

[Mr Cob]

Just started using the Sea-Lab #28 kilo blocks...I'm always looking for ways to easily dose and keep up with the tank but in ways that I can't "overkill" with my inability to measure accurately.

Only started using them this week and I haven't seen any noticeable changes other than calcium staying up...PH has not changed either....our systems maintain 8.3-8.4. I haven't checked anything else and only mentioned PH because it's on a probe - easy to read (I hate testing).

your experience?

Rob, I have tried them as well because of some of the "hoopla" made by the LFS. Made them out as the miracle block for your tank. They slowly disolve in your tank as it needs the elements. Like you the only thing they did was keep my calcium and PH levels up.

Always wondered about these.....

Me also... If they keep your calcium/alk/PH levels up, would they take the place and be a cheaper solution that 2 part?

Interested to follow this and also hear others comments or experiences. I am a skeptic under the impression if it seems too easy or good to be true it usually is.

I purchased them to replace 2 part / dosing to raise calcium. I was a big fan of Fiji Gold for calcium but that just wasn't keeping up with the demands of the MCC systems. Have Mike's old kalk reactor as well but I can't find a place for it and frankly it confuses the crud out of me.

I placed the entire kilo block in the sump intake where there is indirect moderate flow. Total water volume on this system is 380g. Kilo block was about $25.

It's supposed to dissolve to replenish depleted elements:

SeaLab Concentrations (ppm)
Aluminum 0.01
Boron 4.6
Calcium 400.0
Chromium 0.00005
Cobalt 0.0005
Copper 0.003
Fluorine 0.3
Iodine 0.06
Iron 0.01
Manganese 0.002
Molybdenum 0.01
Nickel 0.002
Selenium 0.004
Strontium 8.0
Tin 0.002
Vanadium 0.002
Zinc 0.014

Claims...you can't overdose. Old school product that I'm hoping will just keep calcium up.

tagging along. I'm finding that I have to add a lot more kalk than before.

Where did you put it, in the return area? What ppm does it keep your calcium at?

[allan]

oops...

[Mr Cob]

lots of forum posts out there saying it's garbage...reef central, but it might meet my needs, guess I'll see.

I don't suppose it will be this easy, but once your water levels reach 400ppm, does it stop disolving?
