    Wanted: Coralline Algae

    Hello!

    My month-old 32 G tank is currently sprouting light green algae on the base rock & red/brown algae on the glass. As I understand, this is to be expected. My question is this: Is it possible for coralline algae to develop under relatively weak lights? The tank, a Hagen "Waterhome" starter kit, included a double fluorescent canopy. What factors dictate the presence of coralline algae; bulb strength or water chemistry?

    Thanks!

    Are calcium supplements a definite must? Does one have to "seed" the coralline or does it develop exclusive of the presence of other "mature" coralline? (AKA, does one have to introduce a rock with coralline on it so that it spreads throughout the tank...?)

    Thanks again!

    Not neccessary.. but certainly helpful (seeder rock)

    get jeff to give u one of his live rock with coralline growing on it... i don't remember if urs had an actinic light on, but jack up the calcium level... jeff has some calcium additives, if he doesn't i'll give u some when i get back...

    or make a stop at PC.. hehe hehehehe

    oh yea.. he said u don't like ur damsels and want to give them to me (except the velvet)?

    Hm, would actinic lighting help?

    I do love my damsels. Although, I do suppose I'd be willing to spare Ralph (the yellow-tailed fellow) if you want him (& promise to take good care of him). Maybe the three-stripe as well. I'll think about it. I should have invested in a bigger tank (or another tank!). There are so many amazing fish I'd like to call my own!

    When'll you be up next? I need Calcium & a Fluval. :biglaugh2

    You need both calcium and alkalinity in balance. Don't just test for one. Always support your tank with a balanced additive like kalk, Bionic, or a calcium reactor.

    That will help you grow coraline and also keep your Ph up above 8.3 to control nuisance algae.

    not too worried about akalinity, the crushed coral will balance it, kingston water is pretty hard too so no worries about hardness...

    i believe actinic does help... if nothing else it'll make ur tank look nice lol...

    uh i think i go up once midterms are over and if my sister is driving back, dunno when though

    jeff has like 5 fluvals.. steal one of his...

    Actually, crushed coral will do very litle to buffer your alkalinity.

    I would make sure you are balanced with a test rather then relying on your substrate.

    To answer OP question - calc/alk balance is key as Bvoss pointed out. Limit your nutrients to deter nuisance algae and suppliment/balance calc/alk as needed (both are critical).

    I find my coraline grows better under my PCs then my MH FWIW. I have red, pink and purple coraline covering my baserock after 8 months or so..
