(i moved this topic to this forum to see if more ppl would respond)

hey all .. first off hello i finaly decided to register as i have found your site very helpfull in getting a real reef set up going.

I have had tanks for over 8 years now started off with brackish and quickly moved to salt. Tanks have grown and acumulated over time as expected in this hoby. But recently i decided to ditch most my tanks and focus on 1 main tank... it's a reef tank.. now i have been in the hoby for a while so not total noob. but i had some quick questions and wanted to get your thoughts on some of this stuff.

My first question has to do with Phytoplankton and zoo plankton.

from what i understand phyto is nothing more than baby algae and at this point in my reef experence i am producing a healthy amount of some form in my tank on it's own. I fed my rock live dt's for over 4 years now and every day i get a nice thin film i have to scrape off with my magnet and i was wondering if this is enough to suport my corals alone with out having to use dt's or other phytoplankton products?.. some of the film may be hair algae phyto but mostly what ever was in "live DT's phytoplankton" but for food would it mater? on the same note i am growing live brine shrip and wouldn't that replace my zoo's? I have found most frozen foods to be too large of portions for my tank and i got tired of having 2 chop frozen cubes so i went to live brine for the most part and actualy my fish go nuts over the live brine but would it work as a zoo's for the day 2 for the clams and other corals?? ( aprox baby shimp content per day over 200) after doing it for awhile i noticed a suprising similarity to baby brine shrimp and kents liquid zooplankton .
I would truly like to cut out any unnessasary food/ additives. at the moment i am randomly feeding oyster eggs, black powder, powder form phyo or zoo planton / liquid zoo or phyto (kent) and live dt's and the live brine. what i put in is random but i normaly do a zoo and a phyto a day. also i feed the fish krill or saltwater pack or fish food randomly. so you can see where i'm wanting to cut some of them out.


2nd. heaters... ok this is going to seem silly but here is the jist i have had horible luck with heaters... i have tried almost all brands and whats nots and my problems seems to be either voltege leaks or them turning on over temp.. aka my tanks 77 and heaters set at 69 and the dam things running... now i do run a halide and power compact set up (see specs below) so heat is a issue but not that bad but from the casing alone i think it's causing a false reading and kicking on early ... i have had rena / marinland / top fin and others and all of them have seem to have there own problems ... does anyone have a solid sugestion for a heater that wont kick on unless it is truly below 72 as every one i have tried my digital thermo says i'm mid 70's and the dam heaters on or they leak some voltage back in the aquarium.
don't know if any of you have had same experence but i don't have a extreamly large tank and don't want to buy a chiller atm as my tank temp curve is normaly 74- 78 with my light cycle but at night when lights are off is when i need the heater. So i am looking for a solid heater that only turns on/off when it is +/- 2 of target temp or right on

if you guys can give me your input on these things it would be such a help as atm there my bigest questions that i can't seem to answer.


tank setup.
now some of yall have amazing set ups and while this one is not very large and am very pleased with it.

49 bowfront reef
72-78°F; sg 1.023-1.025; pH 8.1-8.2; dKH 8-12 cal 370-400 amm0
nit/nit-0

xp4 canister on random timer about 15 hours of on time has 9w turbo twist inline but i only run that when i feel like it.

multi powerheads on random timers for wave efects
200+ lbs of live rock. (fiji/ tonga / lalo / texas)

Phytoplankton is not "baby algae". It's single celled microalgae. Very different. It doesn't "grow up" into bigger algae (macro-algae) in other words. Excess nutrients from over feeding of it can lead to growth of pest algaes, micro and macro.

I haven't read the rest as I had to stop there and post....I'll read the rest now:)
 
hmm intresting point and true.. what i'm dealing with is the live dt phyto it's covering my rocks and i have some hair algae but my blenny takes care of it pretty well so it's the green dt's that are reporducing i'm pretty sure
