Seachem Purigen & Macro Algae

[chromakey]

I also treated the tank with Aiptasia-X for a few aiptasia. Do you think that would affect the macro algae?

Halimeda is a calciferous algae, so i would probably check your calcium level. the purigen shouldn't have done anything to it, nor should the aiptasia x. What are your other water parameters?

Hi:

I just did all my test with API test kit:

s.g.: 1.025
PH: 8.2
Ca: 420
Nitrite, nitrate, ammonia: 0
kH: 8
PO4: 0

I don't usually dose with any additives. I just do water changes every two weeks. I do have some older additives around so I added a bit for Ca & hardness buffer.

In my other tank the "grape" macro algae turned white and went mushy. I removed it all. I am not sure what causes this.

Thanks,
Michael

Is it NEW Purigen or old? I can see problems arise if bleach was still in the beads after a regeneration.

Hi:

It is brand new. This is the first time I am using Purigen.

I added one piece of dead rock last week. I soaked it for 4 or 5 days. I don't think should have done too much.

When it's time to regenerate, 50/50 water/bleach and then when it turns back to somewhat original color it's done. (or at most 12-24 hrs) After that rinse a few times in water and then use 2x dose for a dechlorinator. Swish often and leave until the bleach smell goes. (again 12-24 hrs) Don't use a declorinator that says 'added slime coat' type of thing as Seachem says this additive will clog the micro pores of Purigen.

I've used for a while so if you needed tips, glad to help.
